摘要

研究发现，当5%的聚乙烯醇水溶液受到波长为172 nm的真空紫外线（VUV）辐射时，溶液结构发生变化，形成聚合物的交联片段，尽管VUV辐射渗透到溶液中的深度很小。

Processes of Structure Formation in Aqueous Poly(vinyl alcohol) Solutions Under Vacuum Ultraviolet Irradiation

It has been found that, when an aqueous 5% poly(vinyl alcohol) solution is subjected to vacuum ultraviolet (VUV) radiation at a wavelength of 172 nm, the solution structure changes to form crosslinked fragments of the polymer despite the fact that VUV radiation penetrates into the solution to a small depth.

期刊介绍： Colloid Journal (Kolloidnyi Zhurnal) is the only journal in Russia that publishes the results of research in the area of chemical science dealing with the disperse state of matter and surface phenomena in disperse systems. The journal covers experimental and theoretical works on a great variety of colloid and surface phenomena: the structure and properties of interfaces; adsorption phenomena and structure of adsorption layers of surfactants; capillary phenomena; wetting films; wetting and spreading; and detergency. The formation of colloid systems, their molecular-kinetic and optical properties, surface forces, interaction of colloidal particles, stabilization, and criteria of stability loss of different disperse systems (lyosols and aerosols, suspensions, emulsions, foams, and micellar systems) are also topics of the journal. Colloid Journal also includes the phenomena of electro- and diffusiophoresis, electro- and thermoosmosis, and capillary and reverse osmosis, i.e., phenomena dealing with the existence of diffusion layers of molecules and ions in the vicinity of the interface.
