A Simple Method for the Production of Hydrogels Based on Hemicellulose in Aqueous Solution1

摘要

A simple method of bamboo hemicellulose-based hydrogel with multiple responses properties was proposed employing glow discharge electrolysis plasma (GDEP). The network of hydrogels was characterized by Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The mechanical properties, swelling, and stimuli responses were also investigated. The results showed that swelling ratio of hydrogel under 570 V and 90 s was 903.6 g/g. Too long discharge time or high discharge voltage indicated high compression stress and modulus. The hydrogels exhibited excellent sensitivity to pH and salts, which indicated their widely application such as adsorption, separation, and drug release systems.
