The crystalline structure changes of pp induced by pan - milling were characterized by x - ray diffraction and raman spectroscopy . xrd analyses show that when pp was co - milled with uhmwpe , crystal transformation of pp occurred , its crystallinity and crystallite size decreased , whereas , only slight reduction of crystallinity and crystallite size were observed and no crystal transformation was found when pp was co - milled with wtr chips , and amorphization of pp was strongly enhanced by co - milling pp with iron 采用x -射线衍射研究了聚丙烯碾磨粉碎过程微观结构变化, uhmwpe存在下pp发生晶型转变、结晶度降低和晶粒尺寸减小;弹性材料wtr抑制pp塑性变形,碾磨导致分子堆积有序区域膨胀,晶面间距增大,结晶度下降;刚性材料金属铁与pp产生强烈摩擦,加快晶粒细化,晶格破裂导致非晶化。
