摘　　要：高密度聚乙烯／超高分子量聚乙烯共混物高取向薄膜形态结构与力学性能的研究张伟广，赵勇，杨德才中国科学院长春应用化学研究所，高分子物理开放实验室，长春，１３００２２）关键词ＨＤＰＥ、ＵＨＭＷＰＥ、共混物、形态结构、力学性能如何提高高分子材料抗张强度和模量...he morphology and properties of highly oriented films of blends ofHDPE/ UHMWPE were investigated by electron microscope, DSC and mechnicalproperty measurements. The as-drawn films of HDPE consist of highly oriented lamellar structure.The lamellar growing direchon is vertical to the drawing direction. AddingUHMWPE into HDPE results in formation of fibrous crystals with their fibrousaxis directions parallel to the drawing direction. The number of the fibers in thefilms of the blends increases with the increase of the content of UHMWPE. Thepresence of ultra-high molecular weight component in as-drawn blendsfilms results in the increase of tensile modulus considerably.
