Studies on synthesis of dyes having fluoroalkyl groups and water-repellent dying

Dyes有一个荧光团作为水和油补给剂发挥作用，并有硬报告说它们已经消耗到合成的各种各样的东西。在这项工作中，一种新颖的氟烷基化苯胺通过（1）全氟烷基过氧化物与乙酰苯胺的反应，或（2）全氟烷基碘二胺和碘二胺结合。通过二氮偶联反应、酸和直接染料在芳香环上容易地准备了荧光团基团。我选择了酸染料、应用于尼龙的老化，并基本上从无表面能源、接触角和ESCA表面分析的视点研究了一种新颖的水反应死亡系统。在染料exhaustion的相同数量。water contact angles increased in the order of R-D2f-D2 = CF-D23-D2 < C-D26-D2F-D213-D2（approximately equal）C-D28-D2F-D217-D2， in the latter two cases，尼龙表面可能会明显地改变到水的表面。基于ESCA测量，在F-D21 s-D2到N-D2-D2-D2-D2被视为表面上的荧光融合的新测量。Those FイD21sイD2/NイD21sイD2 peak ratios were highly correlated to the water contact angles。The difference that was observed depending on R2f-D2 could be interpreted in terms of the diffusion of dyes into the bulk。

Dyes having fluoroalkyl groups to function as water- and oil repellent agents have hardly reported owing to the difficulties of syntheses. In this work, novel fluoroalkylated anilines were synthesized by (1) the reaction of perfluoroalkanoyl peroxides with acetoanilide, or (2) the coupling of perfluoroalkyl iodide and iodoaniline. By the diazo-coupling reaction, acid and direct dyes having fluoroalkyl group on the aromatic ring were easily prepared.I selected the acid dyes, applied to the dyeing of nylon, and basically studied the novel water-repellent dying system from the viewpoint of surface free energies, contact angles, and ESCA surface analysis.At the same amount of dye exhaustion, water contact angles increased in the order of RィイD2fィエD2 = CFィイD23ィエD2 < CィイD23ィエD2FィイD27ィエD2 << CィイD26ィエD2FィイD213ィエD2 【approximately equal】 CィイD28ィエD2FィイD217ィエD2, in the latter two cases, nylon surface could be changed apparently to water-repelled. Based on the ESCA measurements, the peak area ratio on FィイD21sィエD2 to NィイD2lsィエD2 was taken as a new measure of fluorine concentration at the surface. Those FィイD21sィエD2/NィイD21sィエD2 peak ratios were highly correlated to the water contact angles. The difference that was observed depending on RィイD2fィエD2 could be interpreted in terms of the diffusion of dyes into the bulk.
