Abstract
In order to develop a new way for utilizing Polyacrylonitril (PAN) fiber wastes, a super-absorbent resin was prepared using the waste of PAN fibers at alkaline hydrolysis condition with Al3+ as cross-linker. The molecular structure of the super-absorbent resin was confirmed by FTIR. The thermal degradation of super-absorbent resin consisted of one main weight loss step. Factors that can influence absorbencies of the super-absorbent resin were investigated, such as the amount of cross-linker. The super-absorbent resin has the water absorbency of 131g/g in distilled water. The super-absorbent resin can be used as a new material to water retention from the soil in agriculture.
