This work reports the engineering of the magnetic properties of composites based on acrylonitrile butadiene styrene (ABS) by the inclusion of different magnetic nanoparticles (MNP). ABS‐based composites with different MNP, including permalloy, Fe3O4, CoFe2O4, Ni, and Co‐carbon coated, with a 10 wt% content have been prepared and their morphological, electric, thermal, magnetic, and mechanical properties evaluated. Films were processed by solvent casting under two different processing conditions, no magnetic field applied during solvent evaporations, and an out‐of‐plane magnetic field application. It is shown that ABS‐based composites preserve the magnetic properties of the filler, providing a simple way to tune the magnetic behavior in the polymer. The inclusion of permalloy, Fe3O4, CoFe2O4, Ni, and Co‐carbon coated fillers, allow to obtain saturation magnetizations of 6.2, 4.1, 7.3, 3.7, 4.4, and 4.9 emu/g, respectively, and coercive fields of 88.5, 30.9, 128, 2529.8, 123.6, and 197.4 Oe, respectively. It was found that the mechanical properties of the composites depend on filler type and dimensions, maintaining the thermoplastic behavior of the matrix when the fillers are small (up to 40 nm) and losing it when the fillers are bigger (from 60 to 135 nm). Further, the breaking stress, elongation at break, and the Young's modulus are material dependent, showing higher values when the fillers are Fe3O4 and CoFe2O4 and lower values when the fillers are permalloy, Ni, and Co‐carbon; for example, these values are the highest in the case of the ABS‐Fe3O4 composite with values of 28.7 MPa, 4.1%, and 1266.9 MPa, respectively, while ABS‐Co composite shows the lowest breaking stress and elongation at break with 9.2 MPa and 1.5%, respectively. The ABS‐permalloy composite presents the lowest Young's modulus with 781.5 MPa. Also, the magnetic fillers do not change significantly the thermal, dielectric, and the electrical properties of the composites at this concentration (10 wt%). Overall, the present work demonstrates the feasibility of the modulation of the mechanical and the tuning of the magnetic properties of ABS‐based magnetic nanocomposites by changing the magnetic material and by applying a magnetic field during the processing of the composites, allowing their application in areas including sensors, actuators, and magnetic devices.Highlights Magnetic nanoparticles can engineer the magnetic properties in a composite. Nanoparticles (NP) can engineer mechanical properties depending on their material. NP can engineer mechanical properties depending on their dimensions. With this process, the thermal, electric, and dielectric properties are preserved. Applied magnetic fields during solvent evaporations affects the Young's modulus.

“…Thus, not only the physical properties but also robust adhesion strengths are necessary to secure the safety of passengers. 4,5,[18][19][20][21][22][23] Several theories such as mechanical interlocking, electrostatic, diffusion, adsorption, chemical bonding, and weak boundary layers are adopted to elucidate the adhesion of dissimilar materials, 24,25 and the adhesion between ABS and electroplated metal is relevant to the mechanical interlocking among other aspects. The adhesion strength of electroplated ABS is derived from the interfacial structures representing the anchoring effect.…”

Electroplating on acrylonitrile-butadiene-styrene (ABS) is a widely used decorative technique for achieving low cost and light weight. However, the lack of adhesion strength can be a threat to the passenger's safety in an emergency situation. Herein the morphology formation of injection molded ABS and the resultant adhesion behavior was investigated from the perspective of rheological analysis. The polybutadiene (PBD) rubbers and styrene-co-acrylonitrile (SAN) generated a strong internal structure, which became more strengthened at the low shear level of 0.1 rad/s. As shear rate increased, the deformation of PBD was dominant over the shear level of 10 rad/s. Injection molded specimen and door handle showed extremely oriented ellipsoidal morphology at the gate and squashed structure at the parting line. The etched surface morphology directly influenced the physically interlocked structure, and the deformed surface exhibited negative effect on the adhesion property. 8.11 N/cm of peel-off strength of electroplated ABS at the injection rate of 10 mm/s decreased to 4.27 N/cm at the injection rate of 50 mm/s. The decrease in peel-off strength was more noticeable at near gate than center region of the specimen.

“…Acrylonitrile butadiene styrene (ABS) resins have attracted considerable attention due to their superior mechanical properties [1], heat resistance [2], chemical resistance [3], recyclability [4][5][6] and ease of processing [7,8], and are widely used in telecommunications, automotive industry, consumer markets and business machines [9,10]. However, ABS is easily excited by the heat [11,12], light [13][14][15], oxygen [16,17] and other conditions during its processing [18,19], leading to aging degradations of the material. Because the presence of unstable carbon-carbon double bonds in the butadiene microstructure generates macromolecular-active radicals during processing, thermal degradation is promoted and results in a rapid yellowing and brittleness of ABS [20,21].…”

A stabilizer called 2-tert-butyl-6-(3-tert-butyl-2-hydroxy-5-methylbenzyl)-4-methylphenyl acrylate (GM) was mixed in acrylonitrile butadiene styrene (ABS) with the same amount of 9-bis(octadecyloxy)-2,4,8,10-tetraoxa-3,9-diphosphaspiro[5.5]undecane (DSPDP), octadecyl-3-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate (Irganox 1076) and tris(3,5-di-tert-butyl-4-hydroxybenzyl) isocyanurate (Irganox 3114) to investigate the influence of additives on the antiaging effect of ABS in oven aging or repeated extrusion aging. It was found that the ABS doped with the GM stabilizer showed a better yellowing resistance and thermal stability than the ABS doped with other antioxidants. Owing to the fact that the stabilizer can act on the free radicals before it has been peroxidized, it could trap the free radicals as a consequence of directly blocking the oxidation process of the active species, thus solving the problem of oxidative degradation of the materials from the source. This work provides guidance for improving thermal stability of ABS, indicating a promising potential for industrial application.Polymers 2020, 12, 46 2 of 10 the thermal stability of the ABS resin by adding carbon black (CB) to the ABS [24]. Yan's group enhanced the electrical conductivity and thermal conductivity of the ABS via the addition of reduced graphene oxide (rGO) in the ABS resin, because it can tightly wrap the rGO sheet on the surface of ABS microspheres [25]. In addition, Allen's group used other stabilizers to conduct a comprehensive study of K-resin by both thermal-aging degradation and photo-aging degradation [26]. However, the doping strategy also brings about changes in the color-phase morphology or other properties thereof. This dilemma makes it difficult to explore the improved thermal stability for the ABS resin [27].Here, we successfully obtained high thermal stability ABS through a doping strategy without affecting the properties of ABS itself.A systematic study was carried out to investigate effects of 2-tert-butyl-6-(3-tert-butyl-2-hydroxy-5-methylbenzyl)-4-methylphenyl acrylate (GM), 9-bis(octadecyloxy)-2,4,8,10-tetraoxa-3,9-diphosphaspiro[5.5]undecane (DSPDP), octadecyl-3-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate (Irganox 1076) and tris(3,5-ditert-butyl-4-hydroxybenzyl) isocyanurate (Irganox 3114) antioxidants on the thermal aging of ABS in two different thermal environments, a 100 • C convection oven and a 240 • C extruder simulating the extreme environment. It was found that the ABS doped with the GM stabilizer showed better yellowing resistance and thermal stability than the ABS doped with other antioxidants. Owing to the fact that the stabilizer can act on the free radicals before it has been peroxidized, it could trap the free radicals as a consequence of directly blocking the oxidation process of the active species, thus solving the problem of oxidative degradation of the materials from the source. Hence, the GM antioxidant can greatly improve thermal stability of the ABS in the convection oven or the extruder. This wo...
