What is Electrospraying?
TiO2 particles are used industrially in pigments, catalyst supports, electronic devices, mechanical materials, etc. TiO2 nanoparticles less than 100 nm in diameter, especially, possess interesting optical, dielectric, and photocatalytic properties. Therefore, TiO2 nanoparticles with controlled size, shape, and porosity can be used in thin films, ceramics, composites, and catalysts.
To find a feasible alternative solution for simultaneous preparation and application of titania nano-particles using a one step electrospraying process. This novel technique involves in-situ preparation of titania nano-particles thereby removing any agglomeration problem.
1. K/S study showed a reduction up to 60% in the yellowness of the stained samples treated with titania finish on exposing to sunlight for around 10 hours.
2. The self cleaning activity results of the washed samples confirmed the adherence of finish to the cotton which was further proved by stain repellency phenomenon shown by the washed samples.
