This invention demonstrates a strong bottlebrush pressure sensitive adhesives that is >6 times stronger than commercial VHB1000 tape and is capable of indefinite cycles of wet-dry-wet adhesion (tested up to 50 cycles, 1 month apart). The pressure sensitive adhesives were engineered using the defect-driven design philosophy (D3) where the number of defects in the system is maximized by purposely building large dangling defects into synthesized networks.
