摘要：
Microporous materials that include thermoplastic organic polyolefin polymer (e.g. ultrahigh molecular weight polyolefin such as polyethylene) particulate filler (e.g. precipitated silica) and a network of interconnecting pores are described. The microporous materials of the present invention possess controlled volatile material transfer properties. The microporous materials can have a density of at least 0.8 g/cm and a volatile material transfer rate from the volatile material contact surface to the vapor release surface of the microporous material of from 0.04 to 0.6 mg / (hour cm). In addition when volatile material is transferred from the volatile material contact surface to the vapor release surface the vapor release surface is substantially free of volatile material in liquid form.
