enhancing the mechanical and electrical properties of adhesive coating materials by cu@sn core shell nanomaterials mixed with hybrid polymeric composite material

A new adhesive consisting of cu@sn core shell nanomaterials prepared through a series of chemical deposition reactions to preserve the copper nanoparticles from oxidation, where they were coated with tin. the ultimate goal of this process obtaining certain mechanical, physical and thermal properties. this mixture of cu@sn core shell nanomaterials was added at a weight ratio of 15 % to a polymeric composite material consisting of polyvinylpyrrolidone (pvp) and polyvinyl alcohol (pva) in equal proportions of the two polymer materials (pvp and pva). the mechanical, optical and thermal properties tests of the new adhesive bonding layer, the result which was characterized by a shear stress approximately (τ) 8 mpa and with electrical conductivity (σac) 15 ω cm-1 for cu@sn core shell nanomaterials. after mixing with polyvinylpyrrolidone (pvp) and polyvinyl alcohol (pva), the electrical conductivity was found to be 1.8×10-3 ω cm-1. in light of these results, the new adhesive material promises wide applications in the electronic, automotive, aerospace and medical devices industries due to the attractive properties of the material in addition to its friendliness.
