Recent Progress in the Studies of Molecular and Microstructure of Interfaces in Composites, Coatings and Adhesive Joints

摘要: Recent progress in the studies of molecular and microstructure interfaces interphases composites, coatings adhesive joints is reviewed. Remarkable has been made elucidating structure silane coupling agents their function with respect to dry wet strengths multiphase systems. Amino-silanes attracted major effort past. It now understood that partially cured hydrolyzate complicated. When adsorbed from a natural pH solution dried air at room temperature, approximately half amine groups form bicarbonate salt CO2 air. The rest are either intra- intermolecularly hydrogen bonded neighboring silanol or free bonding. There exists chemical bonding glass/silane metal/ interfaces. surface characteristics, including acidity, topology homogeneity, influence agent. agent interphase shows gradient various properties.
