제목 Nano-fibrillation effect via silylation with wet ball mill method on cellulose and impact on mechanical properties of silicone foam
초록 The aim of this work is the synthesis of silicone foam (SF) containing silylated cellulose for improving the mechanical properties of SF. Cellulose has some drawbacks such as lower thermal stability, moisture absorption, and lower compatibility between matrix and cellulose. To overcome these disadvantages, a tremendous hydroxyl group of cellulose uses as reaction sites for silylation. Moreover, expecting the nano-fibrillation behavior of cellulose by reducing the hydroxyl group and its hydrogen bonds. After silylation reaction, the specific area of cellulose increases at least 10 times, and the compatibility with SF is also enhancing due to the high specific surface area and hydrophobicity. As a result, the tensile strength of SF and silylated cellulose containing SF, extremely increase 9 to 397 kPa.
