六元环缓蚀型天然气减阻剂分子自组装成膜过程分析 Analysis of Self-Assembly Mechanism forAnticorrosion Typed Gas Drag Reduction Agent Molecules with Hexatomic Ring Structure

对六元环缓蚀型天然气减阻剂进行了分子结构分析、溶液的小角X-射线散射分析、成膜表面的原子力显微镜分析。结果表明：六元环缓蚀型天然气减阻剂具有类似表面活性剂结构，分子堆积参数值为0.98，在溶液中自组装形成长约3800 nm、宽约900 nm的平行层状聚集体；经雾化喷涂在钢表面形成长约3800 nm、宽约900 nm的长层片状有序结构。本文总结了六元环缓蚀型天然气减阻剂分子自组装成膜机理。 Structure analysis of the molecular, small angle X-ray scattering analysis of the solution and atomic force microscopy test for the formed film was carried on upon the anticorrosion typed gas drag reduction agent (DRA) molecules with hexatomic ring structure. The results indicated that: the anticorrosion typed gas drag reduction agent molecules with hexatomic ring structure had a surfactant structure with a packing parameter of 0.98, and could self-assembly into parallel la-mellar aggregates with a length of about 3800 nm and a width of about 900 nm; anticorrosion typed gas DRA film was formed after the anticorrosion-DRA solution was coated upon steel surface by atomizing spraying, and the formed film surface had an arranged structure composed of long slices with a length of about 3800 nm and a width of about 900nm. The self-assembly mechanism of the anticorrosion typed gas drag reduction agent molecules with hexatomic ring structure was summarized.
