| Outline of Final Research Achievements |
To improve the performance of cellulosic materials, surface silylation of cellulose using a silane coupling agent: methyltrimethoxysilane was investigated. Two methods for the surface coating have been developed, one was the liquid phase scheme and the other was vapor phase scheme. It should be emphasized that surface silylation yielded water repellency to cellulose by a very simple procedure without changing the aspect of cellulose materials in both schemes. Both coating schemes are applicable to various forms of cellulosic materials such as paper and transparent film.
