Stretchable and recoverable acrylate-based pressure sensitive adhesives with high adhesion performance, optical clarity, and metal corrosion resistance

In the era of Internet Things, digital displays play a critical role in human–machine interfaces. particular, applied to contemporary devices such as flexible smart watches and foldable/rollable electronics underline need for pertinent materials device technologies fulfill their designed functions. However, despite technical advancements electronic components stretchable/flexible electrodes backplanes, proper assembly remains challenge. Herein, we report compositional effect acrylic acid (AA) on physical properties as-synthesized pressure sensitive adhesives (PSAs), especially adhesion performance terms wettability peel adhesion. Accordingly, an empirical criterion intimate wetting is proposed based storage modulus PSAs. this study, PSA with best was evaluated its viscoelastic suitability specific applications. The results demonstrated strain-dependent conformational recovery adhesive; implementation prestrain strategy enables rapid strain reversibility at 25% total strain. Furthermore, AA-incorporated PSAs exhibited remarkable metal corrosion resistance well high optical clarity. Thus, fundamental study stretchable can provide useful guidance development advanced that be used wide range applications involving display devices.
