A method for nano-depth surface activation of a PTFE-based membrane and relates to the technical field of polymer composites is disclosed. The method comprises the following steps: covering a functional surface of a PTFE-based nano functional composite membrane, performing surface activation treatment on a single surface of the membrane to which a bonding adhesive is applied, and migrating and complexing a high-toughness cold bonding adhesive tape on the membrane surface, with an activated structure layer, of the PTFE-based nano functional composite membrane through a mechanical adhesive applying device to form an adhesive-membrane complex. An extremely strong affinity and a high-strength bonding performance are generated between the membrane and the adhesive, and the adhesive-membrane complex is formed. Integration of membrane/adhesive bonding complexing, membrane/membrane bonding complexing and membrane/adhesive layer bonding is realized.

Thermoplastic elastomer compositions comprising acrylic multigraft copolymers are described. The multigraft copolymers comprise a rubbery polyacrylate backbone and a plurality of randomly spaced glassy polyacrylate side chains. The multigraft copolymers can be prepared using a facile grafting through method that can provide copolymers with enhanced purity. The acrylic multigraft copolymers exhibit microphase separated morphologies and “superelastomeric” properties, including an elongation at break, stress at break, and/or strain recovery behavior that exceeds that of conventional triblock copolymer polyacrylate thermoplastic elastomers.
