Aspects concerning the mathematical distribution of metal microparticles on the textile surfaces with electroconductive properties obtained by printing method

This paper presents the aspects concerning the mathematical distribution of metal microparticles on the textile surfaces to model the electroconductive properties of the textiles obtained by a printing method using electroconductive paste based on polyethylene glycol (PEG)/polyurethane (PU) and micro/nanoparticle (nickel, silver, and copper). A direct relationship between surface conductivity and surface pH and an inverse relation surface resistance and pH was observed. Besides this, in this paper, we analyzed the dependences between conductivity, pH and surface resistance by using covariance between two vectors (cov(pH, Rs), cov(C, pH), cov(C, Rs)). The purpose of this research is to define a particles distribution that could be useful in establishing the correct distribution of the microparticles for obtaining the surface with antistatic/dissipative, and conductive properties for sensors or electromagnetic shields.
