Abstract：

Normal liquid paraffin, high boiling point Liquid paraffin and n-hexadecane were used as pore forming agent for the preparation of crosslinked polyethylene microporous membrane. The effects of pore forming agent on the membrane crosslinking and pore forming were investigated. The crosslinking degree was decreased with increasing content of pore forming agent. At the same content of pore forming agent, the crosslinking degree was basically identical. High boiling point pore forming agent can effectively avoid bubble defects on the membrane surface. The porosity of crosslinked membrane after extraction process was lower for n-hexadecane compared to high boiling point liquid paraffin. It was found that n-hexadecane was involved in the high temperature crosslinking reaction process by TG and DSC testing.
