PREPARATION OF PNIPAAm GRAFTED COTTON AND ITS THERMAL SENSITIVITY
棉纤维的N-异丙基丙烯酰胺接枝共聚及产物的温敏性研究

The thermal sensitive cotton-g-PNIPAAm was prepared through free radical grafting reaction initiated by different initiators including ammonium ceric nitrate(CAN),potassium persulfate(KPS) and hydrogen peroxide/ascorbic acid(H_2O_2/H_2A system).The degrees of grafting(G) achieved by different initiators could be sorted into descent order as following: G(H_2O_2/H_2A)>G(KPS)>G(CAN).The other factors affecting the degree of grafting,such as the concentration of initiator,reaction time,temperature and the conce...
