Structure and Properties of Clay/PVDF Nanocomposites Produced by Electrospinning

摘要

In order to explore the feasibility of nanoclay and nanofibers for interior application in buildings and houses, such as shoji paper, wall paper and fusuma paper, two types of nanocomposites consisting of Cloisite 15A nanoclay reinforced PVDF — in film and fibrous forms — were investigated. These were produced using electrospinning and spin casting processes, resulting in nanofiber sheets and thin films. The diameters of the resultant nanofibers were compared before and after vacuum drying. The diameter of the nanofibers was found to depend on the concentration of nanoclay and the presence or absence of vacuum drying. It was found that as clay concentration increased, fiber diameter tended to decrease. The compression properties and thermal properties of these structures were examined using the Kawabata Evaluation System. The results showed that the nanofiber sheets have superior thermal insulation properties and are softer to the touch than thin films. The strength and stiffness of the films were found to be higher than those of the nanofiber sheets. The nanofiber sheets were found to be more flexible and conformable.
