高吸盐水羧甲基纤维素基凝胶织物的制备及其性能
Preparation and performance of carboxymethyl cellulose-based gel fabric with high salt water absorption capacity
摘要
Abstract
To solve the problem of long preparation time and limited saline absorption capacity of existing water absorption materials the liquid metal/choline chloride(LM/PDES)system was in-troduced in the polymerization process of carboxymethyl cellulose(CMC),acrylic acid(AA)and 2-acrylamide-2-methylpropanesulfonic acid(AMPS).CMC-P(AA-AMPS)/LM/PDES gel was deposited and polymerized on the surface of high temperature alkali treated polyester fabric by grafting and crosslinking copolymerization and freeze-drying.FTIR and SEM indicate chemical cross-linking between CMC,PAA and PAMPS,coordination between the Ga3+ion in the LM/PDES system and the carboxyl group(—COOH),and the gel structure showed typical macro-porous properties.The hydrophilic and electrostatic interaction of the CMC-P(AA-AMPS)/LM/PDES gel structure and the anionic groups(—COOH,—HSO3),provide the driving force and space for the absorption of liquid in the gel fabric.The absorption capacity of CMC-P(AA-AMPS)/LM/PDES gel fabric for deionized water,normal saline(0.9％)and synthetic urine can reach 460,60 and 55 respectively;in addition,the gel fabric shows excellent air permeability to ensure wearing comfort for the human body.This paper provides a theoretical reference for im-proving the absorption capacity of water bent materials to aqueous solutions.关键词
