摘要
This study proposed the preparation of light, thin insulating composite layers from potential biocompatible components such as highly porous silica cryogels and cellulose fibers. One of the novelties in this work is the application of cellulose fibers as matrix, and the silica cryogel particles provide the reinforcing phase. The synthesis of silica cryogel was carried out by means of sol-gel chemistry and freeze drying process. The function of additives (NaOH, carbamide, hydroxyethyl cellulose) was to create connections between the components in the composites. The study extended to the investigation of chemical compositions, the time of treatment, as well as the measurements of the dust loss, thermal conductivity, and the adhesion of composites to the various substrates. The bond system of composites was controlled by FTIR, the morphology by SEM. The composites can be characterised by excellent thermal insulation properties (0.048 W/(m⋅K), very low dust loss (0.01 w/w%), and good adhesion to various surfaces.
