Abstract
The halloysite nanotubes (HNTs) were modified using γ-methacryloxypropyltrimethoxysilane (γ-MPS), which interacts with the silanol and aluminol groups of the HNTs. Melt mixing technique was used to formulate the polymer composites using phenyl methyl silicone rubber (PVMQ) and various weight percentages of modified HNTs (mHNTs). The crosslinking density increases as a result of the HNTs modification by γ-MPS, increasing the interfacial and intertubular contacts as well as the degree of dispersion of the mHNTs within the PVMQ matrix. The influence of mHNTs on the cure and mechanical parameters, rebound resilience, abrasion resistance, hardness, heat buildup, and oil and solvent resistance of PVMQ is examined in this work. The amount of mHNTs in the PVMQ increased the maximum, minimum, and delta torque values as well as the optimum cure times and scorch, while decreasing the cure rate index (CRI) values. When the amount of mHNTs is increased, the tensile strength and modulus at 100% elongation of PVMQ rubber nanocomposites rises until 6 phr, after which they fall. The presence of mHNTs was found to improve the mechanical characteristics of nanocomposites, including tensile modulus, tensile strength, and tear strength. Due to the extensive intertubular connection, the PVMQ/mHNTs nanocomposites also showed improved oil and swelling resistance.
