Synthesis and characterization of hemicellulose-based polymeric gel film from tea leaf brewing waste
In this study, hemicellulose-based polymeric gel films were synthesized using the free radical polymerization mechanism. Hemicellulose was obtained from tea leaf brewing waste by using delignification process. Polymeric gel films were produced in accordance with solution-casting technique. The effec...
