AI Article Synopsis
- The study examined the properties of raw and alkali treated Coccinia Grandis L. Fibers (CGFs), highlighting significant changes post-treatment.
- Chemical analysis showed that alkali treatment increased cellulose content while reducing hemicelluloses, lignin, and wax, enhancing various physical properties.
- Key improvements included increased tensile strength, crystallinity, and thermal stability, suggesting alkali-treated CGFs are suitable for reinforcing polymer composites.
Article Abstract
The physical, chemical, tensile, crystalline, thermal, and surface morphological properties of raw and alkali treated Coccinia Grandis.L Fibers (CGFs) were characterized for the first time in this work. The results of the chemical analysis indicate that, after alkali treatment, the cellulose content of CGFs increased whereas hemicelluloses, lignin and wax contents decreased. This directly influenced the tensile strength, crystallinity index, thermal stability and the roughness of alkali-treated CGFs. The thermal stability and activation energy of the CGFs improved from 213.4 °C to 220.6 °C and 67.02 kJ/mol to 73.43 kJ/mol, respectively, due to alkali treatment. The statistical approach, Weibull distribution was adopted to analyze the tensile properties. The improved properties of the alkali treated CGF indicate that it could be an appropriate material for reinforcement in polymer composites.
