Geometric Freezing of In-Situ Fibrillated PP/PA66 Composites via Low-Temperature Injection: Decoupling the Role of Draw Ratio and Compatibilization
Controlling fibril generation and retaining their morphology during secondary thermal processing remain critical challenges for in-situ microfibrillar composites. Herein, we propose a “melt blending–hot drawing–low-temperature injection” cascade strategy to fabricate polypropylene/polyamide 66 (PP/PA66) composites. By...
