Summary
The inclusion of biocidal compounds into modified silica matrices using the sol-gel technique offers new interesting prospects for antimicrobial coatings with controlled release effects. The coatings are well suited for the functionalisation of flexible supports such as paper, textiles and polymer foils as they exhibit good adhesion and improved mechanical properties. It is possible to combine and coimmobilise different biocidal components to expand the antimicrobial efficiency. In the simplest case, modified silica coatings with immobilised boric acid can be used for the protection of wood against biological degradation. Moreover, silica coatings with embedded nanoparticular silver combined with organic biocidal compounds efficiently decrease the survival rate of different bacteria on textiles and medical catheters. Finally, novel types of antimicrobial nanosol coatings with volatile biocidal compounds (VBCs) are presented.
