Polycarbonate (PC) nanofibers were produced using anodized aluminum oxide (AAO) template assisted nanomolding. The effects of temperature on the nanoflow were investigated. It was found that higher temperature apparently enhanced the polycarbonate nanoflow and resulted in longer nanofibers in the same duration. The surface wettabilities of the polycarbonate nanofiber coated substrates showed apparent dependency on the morphology of the surface. It was found that larger honeycomb patterns would result in higher hydrophobicity than smaller honeycomb patterns. POLYM. ENG. SCI., 2012. (C) 2012 Society of Plastics Engineers
