| 제목 | Hydrophilic and Hydrophobic In-chain multi-Functionalized Azido Polyurethanes via Azide-alkyne Click Reaction |
| 초록 | Multi-azido functionalized thermoplastic polyurethanes(Azido-TPU) consisting of alternating sequences of hard and soft segments were synthesized using azido polyetherdiol/MDI/butandiol(BDO). Various alkynyl monomers were used for the azide-alkyne click reaction and introduced into azido-TPU without side reactions under mild reaction conditions. In this work, azido-TPU were functionalized with various alkynyl compounds, such as polyethyleneglycol acetylene(PEGA) and perfluoro octane acetylene(PFOA) via azide-alkyne click reaction with almost complete click yield. Hydrophilic(PEG) via and hydrophobic(PFOA) via functionalized TPU polymers exhibited well-defined unique surface properties such as contact angle. Their functionality and exact structure of multi-functionalized polymers were confirmed by using 1H-NMR, FT-IR, and SEC. |
