The effects of (NH4)2Sx treatment on the surface electronic properties of the thin indium tin oxide (ITO)-doped ZnO films have been examined in this study. Experimental results, found that the formation of S-metal bonds and the removal of oxygen vacancies near the (NH4)2Sxtreated ITO-doped ZnO surface could lead to an increase in the surface energy and the work function, meaning that (NH4)2Sx treatment might be more helpful to form the uniform deposition of the organic semiconductor on ITO-doped ZnO surfaces and improve the efficiency of ZnO-based organic devices.
In this paper, poly (vinylalcohol glycidyl ether) (PVAGE) was synthesized as a novel reactive stiffening agent to improve the stiffness of cotton fabric. Cotton fabric could be grafted with PVAGE under high temperature and the grafting rate would increase with the increase of PVAGE concentration. The cotton fabric grafted with PVAGE has excellent washing durability. The wearability of cotton fabric grafted with PVAGE was also studied. As the increase of grafting rate, the flexural stiffness increased dramaticly; tensile strength increased a little; cockle elastic decreased slightly; and air permeability and whiteness also decreased but were still in acceptable range.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
