ABSTRACT: Currently there has been a growing interest in substituting traditional
synthetic polymers with biobased renewable polymers for adhesive applications.
However, biobased renewable polymers such as starch suffer from few draw-backs
like poor water resistance and mechanical strength. To become important potential
alternatives of synthetic polymers, starch must have comparable physical,
chemical, thermal and mechanical properties to that of synthetic polymers. To
achieve this, starch has been modified by a series of crosslinkers like boric acid, citric acid, glyoxal, gluteraldehyde, etc. and silane modification. Silane modification by chloropropyl trimethoxysilane, γ-Methacryloxypropyl trimethoxy silane
and vinyl trimethoxy silane is a suitable method to improve the performance in
terms of mechanical and thermally. Silane forms covalent bonds with starch
during starch modification resulted in enhanced shear strength and storage
stability. A new research on
biodegradable, renewable, environmentally friendly silane modification of
starch-based wood adhesive that was prepared by
reacting with various silanes. This paper, we reviewed silane as a modifying agent for starch-based wood adhesive.
