SURFACE MODIFICATION VIA REACTIVE POLYMER INTERLAYERS

The reaction of poly[(1-methylvinyl isocyanate)-alt-(maleic anhydride) ] (IAP) with amino-silanized glass and silicon oxide surfaces has been investigated. Different solvents and different adsorption conditions were compared to each other by FTIR spectroscopy and ellipsometry. A r eactive surface containing isocyanate and anhydride groups was formed after the adsorption of the polymer. The latter can be further functio nalized using different-compounds bearing hydroxyl and amino groups. M ixed layers can be established by the reaction of LAP with other polym ers, such as poly(ethylene glycol). Multilayers can be built up by ads orbing a second layer of IAP onto an already functionalized first laye r of IAP.
