水环境下等离子体处理聚乙烯木塑复合材料表面性质的演变
Evolution of Surface Properties for Plasma Treated Wood/Polyethylene Composites Under Water Soaking
摘要
Abstract
The surface of wood/polyethylene (PE) composites was treated by low-pressure glow discharge of air plasma to improve its adhesion properties. To explore the failure mechanism in the condition of water for the bonding joint, the ATR-FTIR and XPS were employed in the soaking experiment to investigate the effect of water on the surface properties of plasma treated wood/PE composites. The ATR-FTIR analysis results showed that the polar groups such as -OH, C - O and C=O were formed on the surface of the composites after plasma treatment. And the number of -OH, C-O and C = O groups on the surface of plasma treated wood/PE composites decreased firstly and then increased with the soaking time extended. The XPS analysis results indicated that the content of oxygen element in the composition of surface element for Wood/PE composites increased after plasma treatment. And the content of carbon element in the treated wood/PE composites surface increased firstly and then decreased and the oxygen element decreased firstly and then increased with the soaking time and the value of O/C descended firstly and then increased. The changes for the surface chemical groups and chemical elements of the plasma treated wood/PE composites would have a considerable effect on the durability of the bonding joint under water soaking.关键词
