Outline of Final Research Achievements |
Ultra-high molecular weight polyethylene (UHMW-PE) contains a huge amount of entanglements. Such molecular entanglements can transmit the applied stress, thus drawing from the molten state is possible for UHMW-PE. When the melt-drawing is uniaxially induced, the desirable extended-chain crystals are firstly formed, and conventional folded-chain crystals are subsequently formed during cooling after melt-drawing. In this study, a series of UHMW-PE having different MWs were biaxially melt-drawn under various conditions. Observed drawing behaviors were compared each other, and entanglement characteristics were discussed. Unique structures and properties of such biaxially melt-drawn membranes were analyzed. Nano-pore formation from the biaxially melt-drawn membranes was achieved by combination of melt-shrinking and biaxial redrawing in the solid state.
