超高相对分子质量聚乙烯(UHMWPE)因具有极小的摩擦系数、较低的磨耗和极为优良的耐化学药品腐蚀、耐冲击、耐压等性能而备受关注。但是因它的相对分子质量极高,在加工过程中熔体流动性极差,致使临界剪切速率低,容易产生熔体破裂等,难以在常规的塑料加工机械上加工成型。聚乳酸(PLA)具有较为优良的生物相容性和生物惰性,产品可以生物降解,是理想的绿色高分子材料。另
Ultra-high molecular weight polyethylene (UHMWPE) attracts much attention due to its extremely low coefficient of friction, low wear and extremely good resistance to chemicals, shock, pressure and other properties. However, due to its extremely high molecular weight, the melt flow in the process is very poor, resulting in low critical shear rate, easy to produce melt fracture, it is difficult in the conventional plastic processing machinery molding. Polylactic acid (PLA) has a relatively good biocompatibility and bio-inertness, the product can be biodegradable, is the ideal green polymer materials. another
