STRUCTURE AND MECHANICAL-PROPERTIES OF METHYLTRIMETHOXYSILANE-TREATEDTAENIOLITE FILMS

Lithium-taeniolite films (9-12 mu m) were soaked in methyltrimethoxysi lane (MTMS) for periods shorter than 48 h at room temperature. The MTM S was hydrolysed by water contained in the film, and the resulting pol ymer buried gaps in the film. The polymer existed also in the vicinity of the film surface. The taeniolite particles constructing the film s eem to be bound by the polymers. Mechanical properties of the films af ter the MTMS treatment showed five times larger modulus of tough ness than that of the untreated film. An impurity of fine LiF particles in the film lowered tensile strength and modulus of toughness.
