The preliminary comparative analysis of different routes for tio2 nanoparticles synthesis and their deposition on textiles. The methyl-orange degradation and vx detoxication study

Abstract

The world-wide use of pesticides together with the possibility of chemical warfare agent's usage in military actions, terrorist attacks or in accidents, increased the risks of chemical contamination occurrence and consequently stipulated the need for the development of new protective materials and equipment with improved properties. Because of that, today in the world, research are directed toward design of the so-called "smart textiles", which are capable of "self-decontamination", i.e. decomposition of toxic chemicals. Therefore, we investigated two methods for the synthesis of TiO2 nanoparticles and their deposition on the standard military textiles (cotton/polyester 50%). Photocatalytic activity of such obtained textiles was tested by degradation of organic dye methyl orange (MeO) and chemical warfare agent O-ethyl S-(2-diisopropylamino)ethyl methylphosphonothiolate (VX), along with the evaluation of their mechanical properties, tearing strength, tensile strength and air permeability.
