UV-curable, highly transparent and flexible PUA nanocomposite films with an effective reinforcement of polyketone nanofibers |
| 초록 |
This study deals with the fabrication of a novel, highly transparent and flexible nanocomposite film based on casting, electrospinning and UV-curing processes. The outstanding characteristics of polymer nanofibers and their excellent mechanical performance offer the use of nanofibers as reinforcement in making nanocomposites. This method allowed the significant enhancement of the mechanical properties using a very small amount (approximately 3.5 gsm) of polyketone nanofiber. The yield strength and Young's modulus of the nanocomposite were improved by up to 61% and 60%, respectively, compared to a UV-cured polyurethane acrylate film. The reinforcing effect of nanofibers was accomplished without sacrificing the transparency and flexibility of polyurethane acrylate. The morphologies of the nanofibers and fiber–resin interface as well as the characteristics of the nanocomposite films were also studied. |
