Surface modification gamma-rays

The interface between plastic and wood fibres strongly influences the mechanical properties of a plastic/wood fibre composite. A means for evaluating the effectiveness of surface treatment on the wood fibres in the PVC/wood fibre composites is presented that investigated the adhesion between PVC and laminated wood veneers. Wood veneers were first treated with gamma-aminopropyltriethoxysilane, dichlorodiethylsilane, phthalic anhydride, and maleated PP for surface modification. The chemical modification made on the wood surfaces was then characterised by different complementary surface analytical techniques X-ray photoelectron spectroscopy and surface tension measurements. 63 refs. 

Grafting polymer by irradiation procedure has been used for the modification of biomaterial surfaces (Stannett, 1990). As irradiation sources, EB (Yamada et al 1990), plasma (Pan, Wesley, Luginbuhl, Denton, Ramer, 2001), gamma ray (Biazar et al., 2010), and ultraviolet (UV) (Biazar, Khorasani, Daliri, 2011 Morra Cassinelli, 1997) are often used for preparing TRCS. These irradiation procedures can be subcategorized into (1) mutual radiation (Pan et al., 2001 Yamada et al., 1990), (2) preirradiation (Biazar et al., 2010, 2011 Della Volpe et al., 1998), and (3) peroxide (Chen, Ito, Imanishi, 1997 Rayatpisheh, Li, Chan-Park, 2012) formation approaches. Mumal radiation includes grafting polymer by EB, plasma, and UV irradiation. In the...
