shape controlled spherical 0d and rod like 1d silica nanoparticles in silica styrene butadiene Rubber nanocomposites role of the particle morphology on the filler reinforcing effect
Polymer, 2014Co-Authors: Roberto Scotti, Lucia Conzatti, Massimiliano Darienzo, Barbara Di Credico, Luca Giannini, T Hanel, Paola Stagnaro, Antonio Susanna, Luciano Tadiello, Franca MorazzoniAbstract:Abstract Silica/styrene butadiene Rubber (SBR) nanocomposites were prepared by blending method using shape-controlled spherical and rod-like nanoparticles with different aspect ratios as filler for the Rubber Reinforcement. The differently shaped silica particles were synthesized by sol–gel method using tetraethoxysilane (TEOS) and (3-mercaptopropyl) trimethoxysilane (MPTSM) as silica precursors, and cetyltrimethylammonium bromide (CTAB) as structure directing agent. This strategy allowed to study the influence of the particle morphology on the reinforcing effect independently of the silica surface chemistry and considering the aspect ratio as the only geometrical variance. Spherical and anisotropic rod-like particles, dispersed in the nanocomposites, formed a network of particles bridged by thin Rubber layers throughout the SBR matrix. Moreover, differently oriented domains of aligned rods are observed when the aspect ratio of particles increases and is ≥2. Dynamic-mechanical properties demonstrated that the rod-like particles with the higher aspect ratio provided stronger Reinforcement of the Rubber. This was related to the self-alignment of the anisotropic particles and to the consequent larger filler/polymer interface, compared to that of spherical ones.
