Polymeric blends based on polycarbonate (PC) and acrylonitrile-styrenebutadiene copolymer (ABS) are applied mainly in the electronic and automotive industries. Studies to improve the properties of PC/ABS blend have led to graphene nanoplates (GNP) addition, a carbon nanofiller derived from graphite that presents some of the promising properties of graphene. In this work, the effect of the addition of GNP (3 and 5 wt%) and maleic anhydride grafted ABS (ABS-g-MAH) were evaluated on the thermal, mechanical, rheological, and electromagnetic properties of PC/ABS blends (85/15), a different blend ratio of previous studies. It was verified that the GNP addition significantly increased the thermal stability of the blends. Furthermore, the mechanical tests showed that ABS-g-MAH acted as an efficient compatibilizer for the PC/ABS blends, and the GNP addition improved the Shore D hardness, the elastic modulus, and the maximum tensile strength of all compositions.Besides, it was observed an overlapping effect of the GNP and ABS-g-MAH addition on the mechanical properties of the blend. The addition of 3 wt% GNP to the PC/ABS (85/15) blend also doubled the elongation at break of the material. Furthermore, these contents resulted in a slight increase of the electromagnetic waves attenuation of 1-2 dB associated to electromagnetic waves reflection.

“…Ultrasonic welding is typically used for textile produced from man-made fibers. For PC/ABS (polycarbonate/crylonitrile butadiene styrene) blends, e.g., both materials of the blend showed different changes according to the vibrational heat during ultrasonic welding, but diffusion of ABS molecules even increased the integrity of the welded joints [ 30 ]. Besides pure thermoplastic materials, composites with carbon fibers and other materials have also been examined for ultrasonic welding [ 31 , 32 ].…”

Preliminary Study of Ultrasonic Welding as a Joining Process for Electrospun Nanofiber Mats

et al. 2018

Electrospinning can be used to create nanofiber mats for diverse applications, from wound dressings and tissue engineering to filters for medical and biotechnological applications. In most of these applications, it is necessary to fix the nanofiber mat on a macroscopic textile fabric, on another nanofiber mat or within a frame to keep it at the desired position. Due to their extremely low thickness and areal mass, however, nanofiber mats are easily destroyed by sewing, and in several situations glued bonds are too thick and not flexible enough. Here we report on ultrasonic welding of polyacrylonitrile nanofiber mats, suggesting this method as a joining process without destruction of the mat morphology for thermoplastic nanofiber mats. A variety of welding patterns results in different adhesion forces between both joined nanofiber mats and different failure mechanisms, with some welding patterns enabling bonding stronger than the mats themselves. Our findings show that ultrasonic welding is a possible joining method for polyacrylonitrile nanofiber mats.

Hybrid nanocomposites of graphene nanoplates (GNP) and multi‐wall carbons nanotubes (MWCNT) might balance the best properties of these nanofillers and proportion synergistic effects to some specific properties as the electromagnetic shielding efficiency (EMI SE). These nanocomposites are being studied in many polymer matrixes, and a promising one should be the blend of polycarbonate (PC) and acrylonitrile‐styrene‐butadiene copolymer (ABS) that are applied mainly in the electronics industry. In this work, the hybrid nanocomposites of GNP/MWCNT in a PC/ABS/ABS‐g‐MAH polymer blend matrix were prepared by melt mixing, using extrusion and injection molding. The rheological, electromagnetic, thermal, and mechanical properties were analyzed to clarify the effect of using individually and both fillers. The morphologies of the hybrid nanocomposites revealed that the fillers were close to each other at the polymer matrix, interacting and forming some hybrid agglomerates. The effect of these hybrids agglomerates was confirmed as a deviation to solid‐like behavior (G′ > G″) in the rheological analyses, and the electrical percolation threshold was only achieved for the hybrid nanocomposites with higher content of nanofillers, 5 wt% of GNP and 1 wt% of MWCNT with electrical resistivity of 106 Ω cm. The same composition had a synergetic effect on the EMI SE properties (11 dB at 8.4 GHz), with a higher attenuation by absorption component, also in the dynamical mechanical, thermal behavior, increasing the Storage modulus and the statical mechanical properties increasing the shore D hardness, the elastic modulus, and ultimate tensile strength. The hybrid nanocomposites of GNP/MWCNT were promising materials for electronic housing with EMI SE properties.
