Multivariate analysis of the 3D composites based on nickel microparticles

This paper presents multivariate analyses of the experimental parameters obtained in the scientific experiments on eightsample fabrics of 100% cotton with electrically conductive properties and electromagnetic achieved through traditionaltreatments such as padding with antistatic agents, and direct printing or scraping with a polymeric paste based on nickel(Ni). Textile printing was obtained using polymers such as polyethylene glycol (PEG), polyvinyl alcohol (PVA),polyacrylate, ammonium salt, carboxylic acid Copolymer polyester, and Ni microparticles. For the eight samples thathave been analyzed, the morphology of the surfaces using SEM (scanning electron microscope) with magnification2000–8000x and electronic magnification microscopy with 4x, assessed the resistance to wet rubbing and dry theresistance of the surface after treatment in the solution of alkaline and acid sweat. Also, the samples above referredhave been analyzed by spectrophotometry to evaluate the transmittance, and reflectance of the electromagnetic waves.It can specify that after treatments in acid or alkaline sweat solutions, the resistance of the surface has decreased by103–105. It has been observed that for samples treated with acid or alkaline sweat, the reflectance was increased incomparison with the reflectance obtained for the original samples. The multivariate analysis provided refers to the studyof some physic-chemical and optical parameters, of the samples collected, such as thickness, pH, reflectance, andtransmittance
