“…13 Therefore, a major research direction is to research coating materials, which not only have better efficacy in slow release of nutrients but also have a low cost and are environment-friendly. 14,15 Degradable water-soluble high molecular weight polymer and natural product are good choices for coating materials, such as cellulose, 16 chitosan, [17][18][19] starch, [20][21][22] polyvinyl alcohol, [23][24][25] polyacrylamide, 26 sodium alginate, 27 lignin. 28,29 These coating materials are environmentally friendly and have a low cost, but their slow release effects are affected by their high water absorbing quality.…”

In order to improve the slow‐release effectiveness of waterborne polymer coated fertilizers, an environment‐friendly coated urea was developed by zeolite and waterborne polymer of starch soluble, polyvinyl alcohol, sodium carboxymethyl cellulose, and chitosan. The properties of different mesh and content of zeolite on the membranes and the slow‐release property of coated urea were investigated. Zeolite decreased water vapor, ammonium permeability and porosity of waterborne polymer with an increased ammonium adsorption, and contributed to improve the slow‐release effectiveness of coated urea. In particular, zeolite‐modified waterborne polymer of 200 mesh and 3% content had best effect with 10.8%, 16.5%, and 59.8% decrease of water absorption capacity, water vapor permeability and ammonium permeability, 17.7% increase of water contact angles. Zeolite‐modified waterborne polymer coated urea for the coating contents of 7% had the best effect on the nutrient accumulate release rate. Therefore, zeolite‐modified waterborne polymers have potential to improve the slow‐release effectiveness of coated urea.

“…[13,14]. A series of PVA -based products have been widely used in biomedicine, food packaging, fabric processing, construction and other fields [15][16][17][18]. Due to the large number of hydroxyl groups on the PVA molecular chain, and the oxygen atoms on the hydroxyl group with unpaired electrons, coordination bonds can be formed with the empty orbital coordination of heavy metal ions to remove heavy metal ions in wastewater [19].…”

In recent years, the treatment of water pollution has been a challenging and far-reaching topic. In order to improve the adsorption performance of polyvinyl alcohol nanofibers, a new nano-adsorbent graphene oxide was introduced into them in this work. The introduction of GO greatly increases the adsorption of Cu 2+ , Methylene blue (MB) and Congo Red (CR). The adsorption kinetics and isotherm analysis of the PVA/GO nanofiber film during the adsorption process showed that the adsorption of Cu 2+ and MB by PVA/GO nanofiber film was mainly chemical adsorption, while the adsorption of CR was mainly physical adsorption. The adsorption process of PVA/GO nanofiber film on Cu 2+ was in line with the Langmuir isothermal adsorption model, that is, single molecular layer adsorption, the distribution of adsorption active sites was relatively uniform, and the increasing temperature was more conducive to the adsorption of Cu 2+ .
