this study was carried out to investigate the effect of esterification on the surface roughness of eastern cottonwood. eastern cottonwood was modified without using any catalyst and solvent at different temperatures and times with two linear chain carboxylic acid anhydrides (acetic anhydride or propionic anhydride). different weight percentage gains (wpgs) were obtained at different conditions....
low temperature plasma technology is well established in surface modification of polymer materials on industrial scale. this method modifies surface properties of polymers without chemicals, manual work and reducing chemicals and energy consumption. in this study, low pressure plasma treatment was used to develop hydrophilic properties of polyethylene terephthalate (pet) fabrics. it was found t...
