Cross-Linkable Polymeric Materials for Adhesion
Researchers at Purdue University have developed a new class of modifiable polymers that incorporate cross-linking groups. The polymers have varied properties, e.g., hardness, crystallinity, and varied degrees of incorporated cross-linking groups. The preparation of the polymers allows for cross-linking with various metals. By combining flexibility in polymer design along with flexibility in cross-linking reactions, we present a new and versatile family of materials, including water-soluble, UV-cure, and solvent applications. Consequently, the design of new materials can include various hardness, adhesive, electronic, and optical properties. These materials were tested for strength on a polished aluminum surface, a traditionally difficult surface for bonding, and showed strong adhesion up to 5 MPa (approximately 750 lb/in2). Bonding strength is on par with superglue without having been optimized. The polymer plus cross-link material is stable in boiling water for up to two hours.
