博士 === 國立臺灣科技大學 === 材料科學與工程系 === 100 === In this study, a series of polyethylene glycol copolymers were prepared by the reaction of combining polyethylene glycol (PEG), Vinyltriethoxy silane (VTES) and N-Vinylpyrrolidone (NVP). One of these polyethylene glycol copolymers is PEG/VTES copolymers, and the other is PEG/PVP copolymers. PEG/VTES copolymers exhibited excellent surface activities, wetting power, as well as low foaming. Consequently, the application of a series of PEG/VTES copolymers can make cotton fabrics stain-resistant. PEG/PVP copolymers are products of biodegradable material polymerizations. The addition of copolymers reduced the overall Zeta potential of the dye and increased the particle sizes. The series of polyethylene glycol copolymers and dyes interacted, as the copolymer enabled shifts of the dyesλmax of UV, reduces the absorbance, which proofs that polyethylene glycol copolymers and dyes can be interactive and foams complex with dye-decolorization function.
