“…Although, most of the studies have focused on the temperature, flow rate, rpm, and number of recycle passes, the effect of compounding sequences on the composite properties has been less studied. The compounding sequence of the components in polymer composites can significantly change the final properties of the composites [35].…”

Three different blending sequences were used to prepare the peanut shell powder (PSP)‐filled polylactic acid (PLA)/thermoplastic corn starch (TPCS) biocomposites. The blending sequences can be summarized as (1) S1: PLA was added, followed by TPCS and PSP, (2) S2: PLA was added, followed by PSP and TPCS, and (3) S3: TPCS was added, followed by PLA and PSP. Various loadings of PSP filler were used from 0 to 40 wt%. The correlation between different blending sequences and PSP filler loading of PLA/TPCS biocomposites were discussed in terms of processing torque, tensile properties, surface morphology, and thermal degradation. Results showed that S1 system is the best blending sequence to prepare PLA/TPCS biocomposites compared to S2 and S3 systems. S1 system had established the low stabilization torque, better tensile strength, elongation at break, and thermal stability. Scanning electron microscopy (SEM) analysis of S1 system revealed better adhesion between filler and the matrix. Incorporation of PSP had influenced the properties of PLA/TPCS biocomposites. Increment of PSP loading increased stabilization torque and tensile modulus while decreasing tensile strength, elongation at break, and thermal stability of PLA/TPCS biocomposites. SEM analysis also managed to detect holes and cavities as the filler pulled out on the tensile fractured surface due to poor adhesion between filler and matrix.

Lightweighting of automotives is crucial for the decrease of fuel and energy consumption, as well as CO2 emission and environmental pollution. Polymer composites, especially the high strength glass fiber/polyamide (GF/PA) composites, have great potential in lightweight; however, they have not been universally accepted due to their insufficient performance. Here, a stearate‐ended hyperbranched polyester (HBP‐12‐n) is designed and high‐performance GF/PA6 composites with high GF content are prepared. The flowability of the composites can be further increased by combining carboxyl‐ended hyperbranched polymer (HyPer C181) with HBP‐12‐n. Compared with unmodified GF/PA6 composites, the melt flow index (MFI) can be increased remarkably to 587% by adding a 0.7 wt% mixture of HBP‐12‐75 and HyPer C181, and the strength and toughness remain competitive. The simultaneous improvement in MFI and impact strength of GF/PA6 composites is the first discovery of this kind, and a synergistic mechanism of amphiphilic bridging‐deformation slipping‐interfacial strengthening of hyperbranched polymers is proposed to account for this phenomenon. This work provides a simple strategy to fabricate GF/PA6 composites with the extensive application for automotive parts and has great prospects in making automotives lightweight and reduction of CO2 emissions.

Lightweighting of automotives is one of the efficient strategies to save energy and reduce CO2 emission and environmental pollution. Glass fiber reinforced polyamide composites (PA/GF) have accounted for about 20% of plastic composites for automotives, showing a large potential to replace metal materials. However, it is an imperative challenge to prepare high‐strength and rapid‐processing PA/GF composites due to poor compatibility between GF and PA. Here, we have synthesized amphiphilic hyperbranched polyesters (H24‐m) containing long aliphatic chains and hydroxyl groups by esterification between hydroxyl‐ended hyperbranched polyester (H24) and stearoyl chloride (SC), which are used to prepare high‐performance GF/PA6 composites. Influence factors on the mechanical properties and melt flow index (MFI) of PA6/GF composites have also been investigated, including GF content, H24‐50 content, esterification degree of H24, and the ratio of H24‐50 to carboxyl‐ended hyperbranched polymer (HyPer C100). The obtained C100/H24‐50/PA6/GF composites show simultaneously high strength, super toughness, high MFI, and high GF content of about 60 wt%. A dispersion‐bridging‐interfacial improvement mechanism has been discovered deeply by investigating crystal behavior, rheological behavior, hydrogen bond interaction, GF length variation, and the synergistic effect of amphiphilic hyperbranched polyester and HyPer C100. This work provides a simple approach to fabricating high‐performance GF/PA6 composites for extensive application in automotive parts, showing great prospects in the lightweight of automotives.
