Adhesion Enhancement of Polymeric Films on Glass Surfaces by Silane Derivatives of Azobisisobutyronitrile
Abstract
Improved adhesion of polymethylmethacrylate (PMMA) and polystyrene (PS) films on glass is achieved by surface-initiated polymerization using a new bidentate free radical initiator obtained from the one-step reaction of 3-aminopropyltriethoxysilane (APTES) with azobiscyanovaleric acid. A THF solution of the initiator was applied (by spin- or dip-coating) on 2''x 2'' glass plates forming a ~300 nm thick xerogel-like film. Heating in the presence of methylmethacrylate or styrene results thick films showing excellent adhesion (5 B, according to ASTM-D3359), as opposed to simple painting PMMA or PS films on glass, which show practically no adhesion (0 B). These results are attributed to covalent bonding of the films with the substrate via the free radical initiator. Thus according to ASTM-D3359, covalently bonded films cannot be removed with a 3M Scotch tape, while simple PMMA or PS coatings are removed completely.
