Abstract:

This paper reviewed the research progress in in?situ fibrillation polymer blends in recent years and introduced the principle, influencing factors, and preparation methods of in?situ fibrillation for PP?based blends, including PP/PA6 and PP/PET in?situ fibrillation blends. The effects of blending ratios, viscosity ratios, and processing parameters such as drawing rate, screw rotation speed, and processing temperature on the morphology of PA or PET microfibers in PP were discussed. The mechanical properties and crystallization behavior of PP were also analyzed.

Key words: in?situ fibrillation, blend, influencing factor, fiber morphology, polypropylene, mechanical property
