| Abstract: | 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. |
