Embodiment 1

[0083] (1) p -Nafluorobutylaniline

[0084] Add 3.44 g of p-bromoaniline, 5 g of copper powder (catalyst) and 100 ml of dimethyl sulfoxide (DMSO) into a 250 ml three-necked flask equipped with a magnetic stirring bar, a thermometer and a condenser, and heat to 60 °C with stirring. Then 9 g of nonafluoroiodobutane was dissolved in 25 ml of DMSO and added to a constant pressure dropping funnel, and slowly dropped into a three-necked flask. After the nonafluoroiodobutane solution was added dropwise, the reaction system was heated to 120 °C and refluxed for 24 h. The reaction system was cooled to room temperature, and the reaction was poured into a 500 ml beaker, and 100 ml of deionized water and 200 ml of anhydrous ether were added at the same time, the layers were stirred, and the copper powder was filtered off. Pour the filtrate into a 500 ml separatory funnel to separate the organic layer and wash it with deionized water (30 ml x 3 times), dry over anhydrous magnesium sulfat...

Abstract

The invention discloses an intelligent textile finishing agent with convertible surface hydrophilicity and hydrophobicity and a method for preparing the intelligent textile finishing agent. The intelligent textile finishing agent comprises effective components which are perfluoroalkyl group azobenzene acrylic ester copolymers. The method includes carrying out esterification reaction on perfluoroalkyl group azophenol and acryloyl chloride to obtain acrylic ester monomers with perfluoroalkyl group azobenzene; polymerizing the acrylic ester monomers, hydroxyethyl methacrylate and butyl acrylate by the aid of emulsion to obtain acrylic ester copolymer emulsion with the perfluoroalkyl group azobenzene. The perfluoroalkyl group azophenol is used as an initial raw material. The intelligent textile finishing agent and the method have the advantages that the usage of initiators is increased during emulsion polymerization, obtained copolymers are low in polymerization degree and have short molecular main chains, and molecular chains are low in twining degree, accordingly, side group azobenzene is high in molecular isomerism capacity, and the surface hydrophilicity and hydrophobicity can be advantageously converted; reaction conditions for preparing the intelligent textile finishing agent which is an intelligent water repellent finishing agent are mild, processes for preparing the intelligent textile finishing agent are simple and convenient, and accordingly the intelligent textile finishing agent and the method are suitable for industrial production.

Description

technical field [0001] The invention relates to a fabric surface finishing agent, in particular to an intelligent fabric finishing agent with switchable surface affinity and hydrophobicity and a preparation method thereof, belonging to the fields of polymer synthesis and textile chemical auxiliary agents. Background technique [0002] The azobenzene polymer mainly introduces the azobenzene structural unit into the polymer chain through chemical bond connection. So far, researchers have synthesized a large number of azobenzene polymers, which are mainly divided into the following four types: terminal azobenzene polymers, side chain azobenzene polymers, and main chain azobenzene polymers. Benzene polymers and doped azobenzene polymers. The azophenyl group has two isomer configurations: the rod-like trans configuration (trans) and the crooked cis configuration (cis), the trans configuration is planar, and the cis configuration is spherical structure. From the perspective of ...
