Abstract
Fluororesin, which exhibits high wear resistance as well as high strength and fracture toughness, can be applied to artificial blood vessel. However, the fluororesin is difficult to glue. To laminate the fluororesin and different polymers of polydimethylsiloxane (PDMS) and polyethylene (PE), the new treatment of hot-press after homogeneous low voltage electron beam irradiation (HLEBI) was innovated without glue. The adhesive force (^oF_p) of peeling resistance of laminated sheets of fluororesin and different polymers of PDMS and PE was evaluated. In order to evaluate the influence of the hot- pressing after HLEBI on ^oF_p, electron spin resonance (ESR) signals related to dangling bonds were observed. When HLEBI cut the chemical bonds and generated dangling bonds with nonbonding electrons at terminated atoms in monomers of fluororesin, PDMS and PE, the nonbonding electrons induced not only the intermolecular attractive force but also chemical bonding. Therefore, the hot- pressing after HLEBI was a useful tool for quick lamination of fluororesin and different polymers of PDMS and PE without glue.
