A Sub-minute Curable Nanoadhesive with High Transparency, Strong Adhesion, and Excellent Flexibility

摘要: To achieve adhesion between two arbitrary substrates, a sub-minute curable dry nanoadhesive was devised in one-step manner. The adhesive is composed of copolymer film containing poly(glycidyl methacrylate) (pGMA) and poly(2-(dimethylamino)ethyl (pDMAEMA) segments, where the tertiary amine moiety pDMAEMA acts as an initiator that triggers ring-opening reaction epoxy ring pGMA, leading to self-cross-linking epoxide groups pGMA. Optimization curing condition resulted dramatic enhancement strength values exceeding 250 N/cm2 shear 32.5 N/25 mm peel strength. Also, strong bonds are observed various types substrate materials including glass, latex rubber, Si wafer, many polymeric films each other. Moreover, it maintained excellent against harsh mechanical, thermal, chemical stresses. copolymer-based developed this study will be highly advantageous for emerging flexible ...
