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 delignification process. Polymeric produced in accordance with solution-casting technique. The effects of synthesis parameters investigated on structure and properties films. For purpose, characterized analytical test. Experimental results indicated that hemicellulose- based absorbed moisture at rate maximum 1% 100% relative humidity environment. lowest water vapor permeability (WVP) value measured to be 5.88?10-10 g/(s Pa m), for film including chitosan. average solubility values varied between approximately 0.4 1.8%. It observed optical transparency changed about 45 65% opacity/thickness 0.0027 0.0011 ?m-1. As a result, it found physicochemical morphological are greatly influenced composition
