PINBOARD SUMMARY

Minimizing the primary petroleum products & developing sustainable tyres

My Ph.D. research program focusses on, namely the development of “Novel Green Tire Technology”. This research was evaluated by a tire industry with a business interest in reduction of automotive fuel consumption. Green tire research stint has enabled me to be appreciative of the importance of sustainability of the environment and the right application of technology in impacting the peaceful ecology on the earth. The primary goal of my research is minimizing the primary petroleum products & developing future high-performance tires. My contribution facilitated a novel avenue to develop the sustainable green tires with ultra-low CO2 emission for better fuel economy, superior abrasion resistance and advanced wet grip for the winter tires. More decisively, naturally occurring bio-resin has been used as a key material to accomplish the task. Our study reveals that the use of bio-resin brings future green tire in the perspective of the “Advanced Magic Triangle of Tire Technology”. A segment of research objective has been accomplished and the findings are novel.

Exploring a highly dispersible silica–elastomer composite for tire applications

Abstract: In this article, we provide an extensive analyses of various properties that are required for tire tread based on developed highly dispersible (HD) silica‐filled epoxidized natural rubber composites. Silica in an HD form has become a staple filler in tire tread applications because of its inherent advantages. In this study, epoxidized natural rubber with 25 mol % epoxide (ENR 25) and natural rubber were mixed with two different types of HD silica for superior reinforcement. A standard tire tread formulation was used as the base compound. The magic triangle properties were conspicuously influenced by the viscoelastic characteristics of the vulcanizates. The introduction of polar rubber (ENR 25) into the HD silica greatly improved rheological, physicomechanical, bound rubber content, and dynamic mechanical properties, and this led to a better, fuel‐efficient tire. We successfully achieved this, even in the absence of a silane coupling agent. ENR 25 played an imperative role in showing an extraordinary rubber–filler interactions and was primarily responsible for these observations. In this study, we explored the HD silica dispersion with transmission electron microscopy observations. Morphological studies revealed well‐dispersed HD silica with the formation of a rubber–filler network. © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 43531.

Biologically sustainable rubber resin and rubber-filler promoter: a precursor study

Abstract: Enthused by the ever growing demand for sustainable and green based materials in responding to applications based on macromolecules, an attempt was made in seeking a bio-resin (Terpene). Herein, we report the functionalization of bio-resin with natural rubber (NR) to produce new sustainable and greener functional polymer. Bio-resin functionalized NR was prepared by melt mixing using di(2-tert butyl peroxy isopropyl) benzene initiator. Structure elucidation of the bio-resin functionalized NR was established by proton nuclear magnetic resonance and Fourier transform infrared spectroscopy, respectively. Bio-resin functionalized NR facilitates the augmented interaction with highly dispersible silica. Amended state of highly dispersible silica dispersion has been achieved in the absence of toxic process oil, expensive silane coupling agent and conventionally used zinc oxide. Remarkable improvement in overall properties corroborated with various meticulous characterization including nanoindentation, rheological, physico-mechanical and small angle X-ray scattering using Becauge model, etc. The dynamic mechanical properties of the greener polymer demonstrated low rolling resistance coupled with high traction. More decisively, the macromolecule system toned up sparingly in the presence of the bio-resin. Our contribution facilitates a novel avenue to develop sustainable high-performance elastomeric macromolecule. Copyright © 2017 John Wiley & Sons, Ltd.
