Abstract
Diplomová práce se zabývá problematikou přípravy anorganicko-organických vrstev metodou sol-gel na textilní materiály na bázi polyesteru a polypropylenu a enkapsulací dalších látek (barviva, nanočástice) do materiálu vrstev. Je rozdělena na část teoretickou a část experimentální. V teoretické části jsou vedle obecných zákonitostí přípravy materiálů metodou sol-gel shrnuty získané poznatky z literatury o přípravě anorganicko-organických materiálů metodou sol-gel a jejich aplikaci v textilním průmyslu. V rámci experimentální části práce byly připravovány anorganicko-organické materiály na bázi alkylalkoxysilanů s funkčními skupinami schopnými polymerace (vinyl a methakryl skupiny) a sledovány podmínky jejich přípravy radikálovou a tepelnou polymerací. Vrstvy připravené z 3-(trimethoxysilyl)propyl methakrylátu byly aplikovány na textilní materiály a byly sledovány jejich mechanické vlastnosti (tuhost v ohybu, koeficient tření). Do těchto vrstev byly úspěšně enkapsulovány i nanočástice oxidu titaničitého a textilní barviva. Na závěr je uvedeno zhodnocení výsledků z hlediska potenciální aplikace v textilním průmyslu.
Diploma Thesis deals with preparation of inorganic-organic coatings using sol-gel process for polyester and polypropylene based textile materials. It also talks about encapsulation of another substances (dye, nano-particles) into material of coatings. Diploma Thesis has theoretical part and experimental part. Besides general regularities of preparing materials by sol-gel process, the thesis includes comprehensive technical knowledge about preparation of inorganic-organic materials by sol-gel process, obtained from technical literature and applications of this method in textile industry. Experimental part deals with preparation of inorganic-organic materials based on alkylalkoxysilane with functional polymerizable units (vinyl and methacrylic units) and monitoring the conditions of it's preparation by radical and thermal polymerisation. Coatings prepared from 3-(trimethoxysilyl)propyl methacrylate were applied on textile materials in order to measure certain mechanical properties like bending rigidity and friction coefficient. Nano-particles of titanium dioxide and textile dyes were also successfully encapsulated into the coatings. The thesis is concluded with interpretation of results in term of potential application in textile industry.
