Anthraquinone dyes for superhydrophobic cotton.
Water-repellent, self-cleaning and stain resistant textiles are of interest for industrial applications. Anthraquinone reactive dyes were covalently grafted onto cotton fabric surfaces obtaining bright colors with good wash-fastness properties and giving rise to breathable superhydrophobic textiles with self-cleaning properties.
متن کاملPolymerization of novel methacrylated anthraquinone dyes
A new series of polymerizable methacrylated anthraquinone dyes has been synthesized by nucleophilic aromatic substitution reactions and subsequent methacrylation. Thereby, green 5,8-bis(4-(2-methacryloxyethyl)phenylamino)-1,4-dihydroxyanthraquinone (2), blue 1,4-bis(4-((2-methacryloxyethyl)oxy)phenylamino)anthraquinone (6) and red 1-((2-methacryloxy-1,1-dimethylethyl)amino)anthraquinone (12), a...
متن کاملDyes and stains: from molecular structure to histological application.
In the present review, the chemistry of dyes as well as the interaction mechanisms between tissue and dye has been detailed, and also some of the key factors affecting the selectivity of dyes by certain cellular structures have been mentioned. Moreover, due to the relevance that histological stains have acquired in biomedical research, some of the most common stains have been described, pointin...
متن کاملExperimental and molecular dynamics studies of anthraquinone dyes in a nematic liquid-crystal host: a rationale for observed alignment trends.
Five anthraquinone dyes with bis(4-propylphenyl) substituents, connected via sulfide or amine linking groups at the 1,5-positions or directly at the 2,6-positions, have been studied as guests in the nematic liquid crystal host, E7. Polarized UV-visible absorption spectra of aligned samples were used to obtain experimental dichroic order parameters, which exhibit values in the range 0.51-0.74. F...
متن کاملEffects of Bismuth Vandate and Anthraquinone Dye on the Photodegradation of Polycarbonate
Compostos orgânicos e inorgânicos, tais como óxidos, sais de metais, compostos policíclicos e azo, são freqüentemente usados como colorantes para polímeros. O pigmento vanadato de bismuto vem sendo usado como uma alternativa a pigmentos baseados em cádmio. Corantes baseados na antraquinona pertencem a classe de colorantes policíclicos amplamente usados em polímeros. Além de suas características...
