Part of the Polymer Science and Technology book series (PST)


The chemical adhesion of poly(amic acid-imide), PAI, films upon silicon, silicon nitride, silicon dioxide and aluminum substrates was examined as a function of surface modification by γ-aminopropyltriethoxysilane, (γ-APS). In these systems it has been observed that curves describing the kinetics of PAI dissolution provide a useful means of discriminating differences in the solvent resistance of the PAI-substrate interphase, A ranking of the chemical adhesive interaction of PAI films on Y-APS modified substrates has been shown to go as AlxNy<Si<SiO2. This substrate effect has been shown to act in concert with an effect arising from the thickness of applied γ-APS layers. These two effects have been discussed in terms of coherence of the PAI-γ-APS-substrate interphase, short range γ-APS-substrate interactions, and the acid-base character of the substrate.
