摘要
Acrylic acid was grafted onto the surface of cotton fabric after being short time treated by corona-discharge inair in the presence of initiator.The means of gas-phaseSO<sub>2</sub> derivatization was used along with ESCA to deter-mine corona-discharge-induced-hydroperoxidegroups on the surface.The content of hydroperoxideshows a maxmium value at 15 sec.of corona-dischargetime.Effect of corona treatment time and various con-centration initlator on graft yield was studied.The addit-ion of initiator increases the graft yield.Acceleratedgraft with an increase in the concentration of Mohr’s saltshows that peroxide groups on the corona treated cottonfabric initiate graft copolymerization.
Acrylic acid was grafted onto the surface of cotton fabric after being short time treated by corona - discharge in air in the presence of initiator.The means of gas - phase SO2 derivatization was used along with ESCA to determine corona - discharge - induced - hydroperoxide groups on the surface. The content of hydroperoxide shows a maxmium value at 15 sec. of corona - discharge time. Effect of corona treatment time and various concentration initiator on graft yield was studied. The addition of initiator increases the graft yield. Accelerated graft with an increase in the concentration of Mohr's salt shows that peroxide groups on the corona treated cotton fabric initiate graft copolymerization.
