摘要

The aim of this study is the development of the UV-curable polyurethane acrylate-based transparent nanocomposite by using electrospun nylon 6 nanofibers as reinforcement. To accomplish the perfect embedment of nylon 6 nanofibers, over-coating is the leading advantage on account of the ultrafast wetting and chemical interaction with the UV-curable PUA matrix system. The remarkable properties of nylon 6 nanofibers offer the use of a very tiny amount of nanofibers as reinforcement in developing nanocomposites, which allowed a significant improvement of the mechanical properties. We developed optically transparent and flexible nanocomposite films and coatings based on casting, electrospinning, and UV-curing. The reinforcement of nanofibers in the nanocomposites maintains 89%-93% optical transmittance in the visible light range with remarkable enhancement of the tensile strength by 85% for 240 min nanofiber deposition in nanocomposite films. The annexed results generated much consideration and proved that the embedment of nylon 6 nanofibers leads to a wide range of applications for pre-coated metals. The morphologies of the nanofibers and properties of the thin film composites were also investigated. The potential utilization of nanofibers as a reinforcement and the fabrication of a nanocomposite along with its characterization comparably to the UV-cured polyurethane acrylate film are also discussed.
