Abstract: | The hydrophilic nature of cellulose fibers often results in poor compatibility with hydrophobic polymer matrices. Therefore,
it becomes necessary to modify the surface of natural fiber for better binding between fiber and matrix. Chemicals are commonly
used for the modification of cellulosic materials but large amount of solvents are usually involved. Microwave radiation induced
grafting is one of the promising methods for the surface modification of natural fibers. In the present paper, we have reported
the microwave radiations induced grafting onto sisal fibers (Agave sisalana) using methyl methacrylate monomer, which has been compared to the surface modification of sisal fibers using bacterial cellulase.
The effects of these treatments on the properties of sisal fibers are discussed in the present paper. The modified fibers
were characterized by scanning electron microscopy, X-ray diffraction, and thermogravimetric analysis/differential thermal
analysis techniques to determine their morphology, crystallinity and thermal stability. |
