Abstract
Functionalized block copolymers consisting of poly(ethylene glycol) (PEG) and polylactide (PLA) were studied and their construction of brush surface was investigated. A novel way of functionalizing PLA surfaces by transforming the acetal group at PEG-chain-end into aldehyde group, after the construction of PEG/PLA surface was also introduced. The surface characterization suggested the construction of PEG brush surface on PLA surface. Further, the presence of aldehyde group on PEG surface after the conversion of acetal end was confirmed by ESR measurements using TEMPO derivative.
