Abstract

See full text

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.
