Abstract
The extraction of cellulose was obtained from the bamboo plant Yushania alpina, a native species of Ethiopia, and synthesizing of hydrogel from carboxymethyl cellulose, and cross-linked polyethylene glycol with different concentrations for medical application in chronic wound dressings. New cellulose was prepared from a bamboo plant in different mesh sizes powder. Optimization of cellulose has been done by using different techniques like double and single string alkalization treatment recovering 45.5% of cellulose. Carboxymethylcellulose was synthesized from cellulose and monochloroacetic acid by the process called carboxymethylation or etherification. Prepared carboxymethylcellulose is water-soluble, unlike native cellulose. Fourier transformed infrared spectroscopy (FT-IR), and x-ray diffraction (XRD) characterization techniques were employed to investigate the functional group and structure of processed cellulose. Additionally, the moisture content of cellulose was analyzed by using a moisture analyzer and porosity test has been implemented. The hydrogel was synthesized from carboxymethyl cellulose (CMC) and with different concentrations of cross-linker polyethylene glycol (PEG). 15 and 20 ml of polyethylene glycol were used to enhance the properties of the hydrogel. Hydrogel has been characterized by FT-IR and XRD techniques. The water absorption capacity of hydrogel was also investigated.
