Effect of dispersants on the hydroxyapatite‐filled natural rubber biocomposites with enhanced functional properties

The aim of this work was application of the hydroxyapatite (HAP) in various amounts by weight as a filler of natural rubber (NR) biocomposites. Silanes, i.e., (3-aminopropyl)-triethoxysilane (APTES) and bis[3-(triethoxysilyl)propyl] tetrasulfide (TESPTS), surfactant, i.e., cetyltrimethylammonium bromide (CTAB), and alkylimidazolium ionic liquids (ILs) with different anions, i.e., 1-butyl-3-methylimidazolium chloride (BmiCl) and 1-decyl-3-methylimidazolium bromide (DmiBr), were used to improve the dispersion of the HAP and curatives particles in the rubber matrix, and consequently the curing characteristics and properties of the NR biocomposites filled with HAP.
