| abstract | METHOD OF SUECRICALLY PRODUCTION OF XEROGELS AND HYBRID MONOLYTIC AIRCRAILS OF SILICA AND MODIFIED LATEX WITH ALCOXISSILAN GROUPS AND THEIR USE. A method of subcritical production of silica / latex hybrid monolithic xerogels and aerogels is described. Hybrid alkogels are synthesized in two steps with acid / basic catalysis of hydrolysis / polycondensation reactions of an excess water silicon alkoxide in an organic medium. A polybutyl methacrylate / polybutyl acrylate latex, modified with alkoxysilane groups, is synthesized and incorporated into the mixture either in the first step for co-hydrolysis with silicon alkoxide or in the second for co-condensation with pre-colloidal silica. hydrolyzed. The alcogels are aged, washed and dried under subcritical conditions. Hybrids containing 0.1 to 50% by mass of latex are obtained, with densities between 300 and 1300 kg.m3, porosities between 40 and 852-, surface areas between 400 and 900 m2g 'and average pore diameters between 2 and 12. nm. The materials are stable to atmospheric humidity, have improved mechanical properties compared to inorganic ones. |
