Abstract

The main objective of this study was to develop improved functional textiles for marine leisure clothing. Neoprene fabrics we re coated with carbon nanofibers (CNFs)/ Poly(vinylidenefluoride-co-hexafluoropropylene) (PVDF-HFP) composite solution compris- ing 0�16 wt% CNF in 1�5 wt% PVDF-HFP via electrospinning. Electrospinning was carried out from 15 to 24 kV. Neoprene textiles coated with the CNF/PVDF-HFP composite with various applied voltages were characterized as follows: Morphology was examined using an image analyzer microscope system and a field emission scanning electron microscope (FE-SEM). The thermal storage property of these materials was also analyzed using a ther- mal imaging camera with a forward looking infrared (FLIR) system. The resultant samples that were laminated with a knitted fabric composed of 80% nylon and 20% polyurethane were subjected to a thermal insulation property test. The test and control specimens were irradiated for 60 min. The test specimen and the control specimen were analyzed by con- sidering the differences in temperature between both specimens on heating. Water pene- tration resistance of the laminated knitted fabric with the CNF/PVDF-HFP composite nanoweb-coated neoprene fabric was measured. The water repellent property test was conducted using a drop shape analyzer (DE/DSA 100, Kruse). The results indicated that an increase in the density of nanoweb-coated neoprene fabric surface correlated with improved thermal storage, thermal insulation, water penetration resistance, and water repellent properties. In addition, increasing amounts of CNFs in the CNFs/PVDF-HFP com- posite solution resulted in increased thermal storage, thermal insulation, and water repel- lent properties.
