Abstract
The disclosure relates to a composition of biocomposite based on natural rubber containing sol-bioglass, which is used and intended for insulating layers and pads in flexible antennas which can be worn in close vicinity with regard to the human body without adversely affecting it. According to the invention, the composition of the biocomposite intended and designed for insulating layers and pads in flexible antennas based on natural rubber is filled with sol-gel derived bioglass amounting to a quantitative range starting from 8 to 50 parts by weight with regard to 100 parts by weight rubber and having following list of remaining ingredients: zinc oxide from 2.5 to 3.5, stearic acid from 1 to 2.5, bis (triethoxysilylpropyl) tetrasulfide from 4 to 6, tertiary butyl-benzothiazolyl sulfenamide from 1 to 2.5, sulfur from 1 to 3 and isopropyl-phenyl-β-phenylene diamine from 0.5 to 1.5.
