Title Incorporation of titania nanoparticles in elastomer matrix to develop highly reinforced multifunctional solution styrene butadiene rubber composites
Date 24.01.2019
Number 56196
Abstract Titania nanoparticles are introduced in situ into SSBR matrix (solution of styrene butadiene rubber) by solution sol-gel method under controlled reaction condition that shows outstanding reinforcing efficiency because of its favourable morphological features and enhanced polymer-filler interaction. Surface treatment of titania particles in reactive sol-gel system using an organosilane, TESPT (bis-(3-triethoxysilylpropyl)-tetrasulfide) further strengthens the reinforcement effect. Notably, more than 85% conversion of titania from its precursor (titanium n-butoxide, TNB) is achieved within 1·h reaction time without employing any catalyst. Additionally, controlled growth of titania particles inside rubber matrix imparts particular characteristics of the titania particles that enables them to deliver rich dielectric and antifungal properties to the composites. In-depth investigation of the composites including rheological, thermal, morphological, mechanical, dynamic mechanical, dielectric and antifungal studies have been carried out and structure-property relationship is established in respect to SSBR gum and externally titania filled composites prepared at similar condition.
