Abstract

Abstract:

A type of polyacrylic acid sodium/Phellinus igniarius section composite superabsorbent resin （PISSR） was synthesized through microwave irradiation. A single⁃factor experiment was conducted to investigate the variable ratio scheme and optimize the preparation processes. The as⁃synthesized materials were characterized by FTIR， TGA， SEM， and EDS. The results indicated that the neutralization degree of acrylic acid reached 85 % when the dosage of Phellinus igniarius， initiator， and crosslinking agent was 20 %， 0.60 %， and 0.15 % of acrylic acid， respectively. PISSR presented the highest liquid absorption rates of 652.6 g/g in distilled water and 61.1 g/g in 0.9 % NaCl solution at a microwave power of 500 W. Ion type and electrolyte concentration are two important factors affecting the liquid absorption performance of PISSR. The surface of PISSR is rough， porous， and rich in Na， K and Ca elements， indicating good water retention and re⁃swelling performance.

Key words: Phellinus igniarius segment, sodium polyacrylate, superabsorbent resin, liquid absorption rate, water retention capacity
