ABS filament remains an important feeding material for fused deposition manufacturing (FDM). However, ABS tends to experience warping after printing. The current paper investigates the effect of hBN fill on rheology property and diameter of ABS extrudate. ABS filled hBN composite was prepared by a facile solution mixing method. Rheological characterisation by capillary rheometer shows that ABS filled 5 wt% hBN composite exhibited a higher shear viscosity than the pure ABS. hBN addition appears to increase the shear viscosity of ABS by 62% at the shear rate of 200 s-1, but the increase was reduced to 20% at 1000 s-1. ABS-hBN extrudate surface microstructure deteriorated lesser than ABS extrudate when the shear rate increased up to 1000s-1. SEM micrograph of ABS-hBN extrudate’s surface exhibited less sharkskin feature but its swell percentage is 5.4% higher than the ABS extrudate. The addition of hBN fillers resulted in higher shear viscosity and percentage of ABS die swell but exhibited less sharkfin feature (smoother surface) on extrudate surface than the pure ABS.

“…Biodegradable materials with balanced rigidity (modulus ~1.60 GPa), toughness (impact strength ~40 kJ·m −2 ), and thermal resistance (HDT ~67 °C) are successfully prepared by controlling the properties of polymers at the microscopic level through the concept of heat treatment. Although super-tough PLLA (impact strength > 53 kJ·m −2 or 530 J·m −1 as proposed by Wu) [ 39 ] could not be achieved in this study, the resulting impact is significant to substitute high-impact plastics such as acrylonitrile butadiene styrene (ABS) with the reported impact strengths around 16–21 kJ·m −2 [ 23 , 44 ]. In industry, PLLA and ABS are two of the most common materials used in FDM 3D printing technology.…”

Manipulating Crystallization for Simultaneous Improvement of Impact Strength and Heat Resistance of Plasticized Poly(l-lactic acid) and Poly(butylene succinate) Blends

Crystalline morphology and phase structure play a decisive role in determining the properties of polymer blends. In this research, biodegradable blends of poly(l-lactic acid) (PLLA) and poly(butylene succinate) (PBS) have been prepared by melt-extrusion and molded into specimens with rapid cooling. The crystalline morphology (e.g., crystallinity, crystal type and perfection) is manipulated by annealing the molded products from solid-state within a short time. This work emphasizes on the effects of annealing conditions on crystallization and properties of the blends, especially impact toughness and thermal stability. Phase-separation morphology with PBS dispersed particles smaller than 1 μm is created in the blends. The blend properties are successfully dictated by controlling the crystalline morphology. Increasing crystallinity alone does not ensure the enhancement of impact toughness. A great improvement of impact strength and heat resistance is achieved when the PLLA/PBS (80/20) blends are plasticized with 5% medium molecular-weight poly(ethylene glycol), and simultaneously heat-treated at a temperature close to the cold-crystallization of PLLA. The plasticized blend annealed at 92 °C for only 10 min exhibits ten-fold impact strength over the starting PLLA and slightly higher heat distortion temperature. The microscopic study demonstrates the fracture mechanism changes from crazing to shear yielding in this annealed sample.

“…Especially, poly(lactic acid) (PLA), chitosan, and polybutylene succinate (PBS) have been widely utilized to improve biodegradability of PET due to their good degradability . Many investigations have been reported on physical modification of PET with them via melting blend, such as PET/poly(3‐hydroxybutyrate) composites, PET/PBS composites, PET/PLA composites, and PET/chitosan composites . However, physical blending strategy has been demonstrated that it is not an effective method to address PET pollution issue, because the polymeric chains of PET in these composites are stable during biodegradable process.…”

In the current work, a series of biodegradable poly(ethylene terephthalate-co-ethylene succinate)s (P[ET-co-ES]s) were prepared via a traditional melting polycondensation method. First of all, the structures of prepared copolymers were characterized by nuclear magnetic resonance and Fourier transform infrared measurements. Meanwhile, the thermal properties of prepared samples were analyzed by differential scanning calorimetry and thermogravimetric analysis measurements, respectively. Subsequently, the mechanical properties of the P(ET-co-ES)s were evaluated, the tensile strength of P(ET-co-ES)s decreased with increasing of PES content in copolymer, however, corresponding P(ET-co-ES)s exhibited better elongation at break. Next, the biodegradability of P(ET-co-ES)s was evaluated using lipase as degrading enzyme. The results presented that the biodegradability of P(ET-co-ES)s improved with PES content, the corresponding results were supported by scanning electron microscopy test. Finally, the Mo's modified Avrami equation was employed to analyze the nonisothermal crystallization kinetics of prepared copolymers. The results showed the addition of the PES component improved the crystallization properties of the prepared P(ET-co-ES)s.
