Metallization of dielectrics a new physicochemical, mechanical and decorative properties is give to them 1-7. Depending on the type of dielectric material and on the aims to be coated, have been proposed various methods of metallization, among which was the largest use of chemical-electrolytic metallization 3,4. For create a conductive layer in this process the dielectric surface is activated by formation of a catalytic centers, which are then coated by chemical means. At that the active centers consisting of easily reduce metals atoms (copper, silver, palladium), through reduction of metal ions (adsorbed on the surface of dielectric material) by water-soluble or gaseous reducing agent are formed 1-7. As gaseous reducing agent most commonly used hydrogen, and the reduction reaction at high order of several hundred degrees temperature is carried out.

New thermosensitive hydrogels based on N-isopropyl acrylamide and 2-hydroxyethyl acrylate were prepared in the presence of ammonium persulfate as an initiator using a free-radical technique. The thermal stability as well as the physical and chemical properties of the obtained hydrogel were studied by thermogravimetric analysis, differential scanning calorimetry and scanning electron microscopy. The swelling of the hydrogels was investigated by the cathetometer method. In order to use thermosensitive hydrogels as a carrier of antibiotics (lincomycin and gentamicin), several biological tests were performed. All samples of thermosensitive poly(N-isopropyl acrylamide) and 2-hydroxyethyl acrylate hydrogels containing medical substances exhibited antibacterial activity. The antibacterial activity of temperature-sensitive hydrogels naturally increases with increasing concentration of antibiotics in the carrier. The results obtained indicate a large amount of drug was released from the hydrogels with full retention of antimicrobial properties. These copolymers can be used as an antibacterial material in the field of medicine.

Статья посвящена поверхностной модификации изотактического полипропилена путем радиационной прививки функциональных полярных групп с целью последующей металлизации полимерного материала. Представленные ИК-спектры, результаты измерения краевого угла смачивания модифицированного материала указывают на улучшение гидрофильности поверхности. Установлена степень прививки функциональных групп к поверхности изотактического полипропилена. Предложена схема поэтапного модифицирования поверхности полипропилена. Для получения токопроводящего слоя на поверхности модифицированного полипропилена использован низкотемпературный газо-фазный метод нанесения электропроводящих пленок фосфида меди. Приведены экспериментальные результаты, показывающие, что фосфид меди обладает электрической проводимостью и придает покрытию повышенную твердость.
