Abstract
This chapter reviews the recent advances referring to the use of sol-gel processes and layer by layer (LbL) treatments for conferring multifunctional features to cellulosic fabrics (namely cotton and its blends with polyester). In fact, these two approaches, which have been successfully applied to both natural and synthetic fabrics, can be very effective in providing multifunctional features to the treated fabrics, through the formation of a ceramic - or polymer /ceramic-based coating (sol-gel ), or by depositing a nanostructured organic, inorganic or hybrid assembly (LbL) on the underlying textile. Sol-gel is based on a bottom-up strategy, starting from different precursors, from which it is possible to tailor the final surface properties of the treated substrates. Conversely, layer by layer exploits a top-down method, suitable for the design of very thin and, at the same time, performing coatings. Among the different possible multifunctional properties the two approaches can provide to cellulosic substrates, fire retardancy, hydrophobicity, wear resistance and anti-bacterial activity seem to fulfill the up-to-date needs coming from either the academic or industrial world. This work thoroughly reviews the development and the recent advances achieved by the two strategies, showing their potentialities and current limitations.Pubblicazioni consigliate
