Abstract:
A composite of a vulcanized silicone rubber member formed by a vulcanization of an unvulcanized silicone rubber, and a resin member comprising a thermoplastic resin and directly bonded to the rubber member, wherein the resin member bonds directly to the vulcanized silicone rubber member vulcanized or crosslinked with a radical-generating agent without an adhesive treatment of the resin member, and the thermoplastic resin is a thermoplastic resin having at least 2 atoms, as average, selected from a hydrogen atom and a sulfur atom per molecule, each atom having an orbital interaction energy coefficient S of not less than 0.006,wherein the orbital interaction energy coefficient S is represented by the following formula (1): S=(CHOMO,n)2/|Ecâˆ’EHOMO,n|+(CLUMO,n)2/|Ecâˆ’ELUMO,n|â€ƒâ€ƒ(1) in the formula (1), each of Ec, CHOMO,n, EHOMO,n, CLUMO,n, and ELUMO,n represents a value calculated by a semiempirical molecular orbital method MOPACPM3, Ec representing an orbital energy (eV) of a radical of the radical-generating agent, CHOMO,n representing a molecular-orbital coefficient of a highest occupied molecular orbital (HOMO) of an n-th hydrogen or sulfur atom in a constitutive unit of the thermoplastic resin, EHOMO,n representing an orbital energy (eV) of the HOMO, CLUMO,n representing a molecular-orbital coefficient of a lowest unoccupied molecular orbital (LUMO) of the n-th hydrogen or sulfur atom in the constitutive unit of the thermoplastic resin, and ELUMO,n representing an orbital energy (eV) of the LUMO.
