AI Insight
Researchers at the National Institute for Materials Science have developed a new bonding technique that uses a porous layer created through simple coating and drying to join dissimilar materials. The method combines chemical adhesion to one material with physical interlocking through microscopic pores to bond with another material, achieving bond strengths exceeding 7 MPa even between materials that are typically difficult to join together. This approach functions as a "porous anchor" that bridges materials with different properties.
Why it matters
This technology could simplify manufacturing processes across multiple industries by enabling strong bonds between incompatible materials without complex preparation or specialized equipment. The simple coating and drying process makes it cost-effective and scalable for applications in electronics, automotive, aerospace, and medical devices where joining dissimilar materials is essential.
Understand the Science
The National Institute for Materials Science has developed a technology to strongly bond dissimilar materials by using a porous layer, formed by a solution-coating and drying process, as an anchor. The research team confirm that even materials that are normally difficult to bond together can be bonded with a strength exceeding 7 MPa by adopting a hybrid approach: adhering to one material through chemical affinity and bonding to another via physical interlocking using tiny pores.
