| Abstract |
The present work aims developing a versatile Greensilica (R) vector/carrier, able to bind to a wide range of textile matrices of carbohydrate polymers and susceptible of being loaded with chemicals/drugs/therapeutic molecules, to create a green tailor-made (multi)functional high-tech textile. A green, eco-friendly, ammonia-free, easily scalable, time-saving sol-gel process was established for the production of those silica-based colloidal particles (SiO2, amine-SiO2, diamine-SiO2, and epoxy-SiO2). Two different textile matrices (cotton, polyester) were functionalized, through the impregnation of Greensilica (R) particles. The impregnation was performed with and without cure. Diamine-SiO2 colloidal particles exhibited the higher bonding efficiency in cured textile matrices (both cotton and polyester), while with no cure the best adherence to cotton and polyester textile matrices was achieved with diamine-SiO2 and amine-SiO2, respectively. Use once and throw away and continued use applications were envisaged and screened through washing tests. The efficiency of the textiles impregnation was confirmed by SEM, and quantified by ICP.
