INFLUENCE OF ADDITIVES ON THE CHARACTERISTICS OF NANOPARTICLES
Journal Title: Annals of the University of Oradea. Fascicle of Textiles, Leatherwork - Year 2018, Vol 0, Issue 1
Abstract
Here the influence of additives on NPs in spray formulation used for textiles treatement is assessed. After oleofobization with Tubiguard textile materials from 100% cotton were spray-treated in a specialized chamber with Ag NP and CeO2 NP in 3 sizes ranges (<100nm, <200nm, 2-3μm) in a water – ethanol - based dispersions containing aditional additives. Electron microscopy analyzes by light field, high resolution and electron diffraction on selected area analyses highlighted the spherical and polyhedral form of the nanoparticle the homogeneitiy of the nanoparticles dispersion. Analysis of the uniformity, morphology and distribution of the nanoparticles on textile matrices were performed by using: the SEM (Scanning electron microscope) made on Quanta 200 FEY, the TEM (Transmission electron microscopy) and EDS (Energy-dispersive X-ray spectroscopy), IPC-MS Analyses (Inductively coupled plasma mass spectrometry). Analysis of the influence of the chemical auxiliaries on the shape and dimension of the nanoparticles were made for: solution of CeO2 and Tubiguard VCN-5g/l, Solution of nanoCeO2 and RucoDry(5 g/l) and RukoLink (1 g/l), solution of Ag NPs and Tubiguard VCN(5g/l), solution of nanoAg and RucoDry (5 g/l) and RukoLink (1 g/l).The TEM analysis reveals that dimensions and shape of the NPs did not change under the action of the chemical auxiliaries.
