In the ever-evolving world of materials science, a groundbreaking study has emerged that could significantly impact the energy and automotive sectors. Theertha Prasad Pramod, a researcher from the Department of Mechanical Engineering at Kalasalingam Academy of Research and Education, has delved into the realm of polypropylene-based microencapsulated nanocomposites, uncovering their potential to enhance thermal and wear properties.
The study, published in the journal *Discover Materials* (which translates to *Discover Materials* in English), focuses on the synergistic effects between thermal and tribological properties, striking a balance between cost, performance, and eco-friendliness. Pramod and his team prepared nanocomposites using microencapsulated additives, functionalized multiwalled carbon nanotubes, and maleic anhydride as a compatibilizer.
The research revealed that the average percentage of char yield in the nanocomposites increased from 2.1% to 5.5% as the additive content varied from 10% to 30%, thanks to microencapsulation. This is a significant finding, as higher char yield indicates better thermal stability and flame resistance. “The enhanced thermal stability of these nanocomposites makes them ideal candidates for applications where heat resistance is crucial,” Pramod explained.
Moreover, the study found that as the load varied from 20 N to 60 N, the nanocomposites loaded with microencapsulated additives showed a reduction in wear by more than 47% compared to their non-microencapsulated counterparts. This improvement in wear resistance is a game-changer for industries that require durable materials, such as automotive and infrastructure sectors.
The wear damage morphology of the nanocomposites was assessed using Scanning Electron Microscopy, providing a detailed understanding of the material’s behavior under stress. The developed nanocomposites can be upscaled for use in brake discs, wheel housing, and insulating power cables, among other applications.
The implications of this research are far-reaching. As the world shifts towards more sustainable and efficient energy solutions, the need for materials that can withstand extreme conditions becomes paramount. The enhanced thermal and tribological properties of these nanocomposites could pave the way for more robust and long-lasting components in various industries.
Pramod’s work is a testament to the power of innovation in materials science. As he puts it, “This research opens up new avenues for developing high-performance, eco-friendly materials that can meet the demands of modern industries.” The future of materials science is indeed bright, and this study is a significant step forward in that journey.
