聚丙烯醇做土壤改良剂研究:老化与作用力分析
PVA Used as a Soil Conditioner: Aging and Interaction Forces with Soils
摘要
Abstract
Polymers used as soil conditioners to enhance the capability for protection against erosion of soil are important topics in environmental study. Polymer soil conditioners can stabilize the aggregates of soils, increase the infiltration and reduce the runoff and erosion of soil. In this work polyvinyl alcohol (PVA) was used. Its degradation in soils and its intermolecular interaction force with soils were studied. Pure PVA film、PVA with silica and PVA with alumina oxide were heated or treated with ultra-visible light. FTIR was used to observe the aging of PVA. The surfaces of the specimens were observed with SEM and AFM (atomic force microscope). Interaction force between PVA and the tip was measured with AFM. The effects of soils on the aging of PVA were discussed according to the experimental results. Effects of treating methods on the interaction force between soils and PVA were also discussed in this study.关键词
