To achieve adhesion between substrates while maintaining the flexibility of the bonded substrates, an ultrathin but sub-minute curable dry adhesive was devised in a one-step initiated chemical vapor deposition (iCVD) process. The dry adhesive is composed of a copolymer film containing poly(glycidyl methacrylate) (pGMA) and poly(2-(dimethylamino)ethyl methacrylate) (pDMAEMA) segments, where the tertiary amine moiety in pDMAEMA acts as an initiator that triggers the ring opening reaction of the epoxy ring in pGMA, to lead a self-crosslinking of the epoxide groups in pGMA. Through optimization of the curing condition, the adhesion strength achieved in value of 250 N/cm2 of shear strength and 32.5 N/25 mm of peel strength. It showed outstanding mechanical flexibility, high optical transparency, and strong bond between various types of substrate materials including glass, latex rubber, Si wafer, and many polymeric films to each other, with strong chemical, mechanical stability. |
