Abstract
We have studied the structure of γ-methacryloxy-propyltrimethoxysilane (γ-MPS) interphase as well as the glass/γ-MPS interface using FT-IR. Multilayer formation of γ-MPS on the surface of E-glass fibers was reconfirmed and the results are in good agreement with the work using 14C-labeled γ-MPS. The amount of γ-MPS adsorbed increases linearly with concentration in solution. There is a sudden change in the amount of adsorbed γ-MPS at around 0.4% by weight. This transition is associated with the onset of incomplete dispersion of the coupling agent in the solution. There is a significant amount of γ-MPS in the outermost layers that can be washed away by organic solvents. The more tightly bound layers of γ-MPS undergo, in addition to the siloxane reaction, surface induced homopolymerization of acrylic polymer and loss of most of the organofunctionality. The surface induced homopolymerization arises due to the surface catalytic effect of the acid centers that strongly interact with the carbonyl groups of the γ-MPS. The area occupied by a single γ-MPS molecule at the surface is experimentally determined to be 48Å2 which is in fair agreement with the expected size of the molecule.
