| Popis: | Chitosan-grafted-polyethylene (CS-g-PE) film was prepared using simultaneous radiation-inducing grafting technique. The copper ion (Cu2+) adsorptivity on the CS-g-PE film was determined. The CS-hydroxybenzyltriazole (CS-HOBt), CS-N-hydroxysuccinimide (CS-NHS), CS-acetic acid (CS-HOAc), and CS-glutathione (CS-GSH) were used as CS-salts in aqueous solutions. Among these grafting solution systems, the CS-g-PE film prepared from CS-HOBt solution showed the greatest grafting amount and highest Cu2+ adsorptivity, up to 30.2% (1.51 ppm, 7.56 µg cm−2). The effects of the CS-HOBt concentration and mixing solution on the grafting amount were also observed to clarify their efficacies to assist radiation-induced grafting reaction. SEM/EDS mapping, ICP and XRF were used to clarify the Cu2+ adsorption capacity of the CS-g-PE film and the stability of Cu2+ on the CS-g-PE complex film. The Cu2+ showed its stability on the CS-g-PE film at room temperature in neutral and basic solutions. The Cu2+---CS-g-PE complex film reduced pest snail breeding as high as 54%. The success of this observation is a new approach to modify PE surface with a functional biopolymer, CS containing Cu2+ complex for controlling pest snail breeding. © 2014 Wiley Periodicals, Inc. J.
