聚合物表面与界面会议于1996年10月20～23日在美国召开。有54人与会,分别来自大学、研究机构和企业。会议的主要内容有以下一些。 (1)聚合物表面及界面的基础理论研究。用模型聚合物的混合物来表征表面的浓度与润湿,润湿动力学、伸展速度与材料的化学结构及温度的关系,在聚合物相界面接枝链的动力学,润滑剂在固体表面形成薄膜的润湿和可动性等。 (2)表面与界面层厚度测量技术。用X射线与中子反射来测定超薄聚合物薄膜的厚度,还用测定厚度与温度的关系来测定聚合物薄膜的热膨胀系数。
Polymer surface and interface meeting was held in the United States from October 20 to 23, 1996. Fifty-four participants were from universities, research institutes and enterprises. The main contents of the meeting are the following. (1) The basic theory of polymer surface and interface. The mixture of model polymers is used to characterize the relationship between surface concentration and wetting, wetting kinetics, stretching speed and the chemical structure and temperature of the material, the kinetics of graft chains at the polymer phase interface, the formation of lubricants on the solid surface Film wetting and mobility and so on. (2) surface and interface layer thickness measurement techniques. The thickness of the ultrathin polymer film was measured by X-ray and neutron reflection. The thermal expansion coefficient of the polymer film was also measured by measuring the relationship between the thickness and the temperature.
