摘要： The present invention relates to the field of pigments and pigments, more particularly to the field of particles with immobilized UV-responsive pigments and to the field of processes for the preparation of said particles. The essence of the invention is in the preparation of mesoporous reversible UV-responsive SiO 2 nanoparticles, which due to their specific surface area and porosity will allow the immobilization of large amounts (up to 30 wt.%) of a spiropyran pigment. The process for preparation of SiO 2 UV sensory particles, wherein the process is based on a sol-gel method, i.e. hydrolysis and polycondensation of tetraethoxysilane (TEOS) and/or phenyltrimethoxysilane (PhTriMOS) in the presence of a pigment selected in the family of spiropyrans, preferably 1,3,3-Trimethylindolino-6'-nitrobenzopyrylospyran.

摘要： The present invention belongs to the field of chemical and electrochemical processes for preparing conductive silver/polyaniline (Ag/PANI) nanostructures, more precisely to the field of processes for preparing conductive silver/polyaniline (Ag/PANI) nanocomposites with the use of functional alkoxysilanes as capping agents.
The essence of the process for synthesis of conductive silver/polyaniline (Ag/PANI) nanocomposites is that it includes high-temperature polyol synthesis based on organic colloidal solution of silver nanoparticles with the particle size distribution 70 ± 20 nm and the use of functional trialkoxysilane molecules as capping agent, followed by admixing the prepared colloidal silver solution into organic aniline solution and finally the polymerization of aniline monomers with potassium iodate at room temperature in an acidified aqueous medium with pH value 0.5 and aniline-to-potassium iodate molar ratio 1. Colloidal solutions of silver nanoparticles have such properties that as a dopant, they enable textiles treatment, which gain in quality. Improved are properties such as conductivity (conductivity can be close to the conductivity of metals), antistatic properties, antimicrobial properties, fire resistivity and depending on the type of the dopant, even mechanical properties. In this way they combine electrical properties of metal with advanced properties of the polymer, such as low weight, easier treatment, corrosion resistivity and low price.
