Nanodiamonds Revolutionize High-Tech Textiles for Enhanced Cooling

In a groundbreaking initiative, researchers at RMIT University are harnessing the potential of nanodiamonds to engineer advanced textiles capable of rapid cooling. Utilizing a technique known as electrospinning, the team has successfully coated cotton fabrics with nanodiamonds, showcasing a remarkable enhancement in cooling efficiency. Compared to conventional cotton, these high-tech textiles imbued with nanodiamonds exhibit a cooling effect of two to three degrees Celsius. This innovation holds immense promise for commercial applications, offering a viable solution for combating heat discomfort.




Renowned for their exceptional thermal conductivity, nanodiamonds facilitate the efficient dissipation of body heat from the fabric. Moreover, the incorporation of nanodiamonds enhances the UV protection of textiles, rendering them particularly suitable for warm climates and seasons. This advancement not only promises personal comfort benefits but also presents an opportunity for substantial energy conservation, potentially reducing air conditioning usage by up to 30 percent.




The application of nanodiamond-infused textiles extends beyond personal apparel, with implications for broader industries. Dr. Shadi Houshyar, the lead researcher, underscores the versatility of this technology, envisaging its integration into sportswear and protective clothing, including firefighter gear. Even a modest reduction of a few degrees can significantly impact comfort and health outcomes, presenting a compelling case for widespread adoption.


Furthermore, the biocompatibility of nanodiamonds opens doors to biomedical applications. Through a meticulous process involving adhesive coating and electrospinning, nanodiamond-infused nanofibers are seamlessly integrated with cotton fabric, ensuring direct skin contact for optimal heat absorption and dissipation. Dr. Aisha Rehman emphasizes the safety and potential of nanodiamonds in both textile and biomedical realms, signaling a paradigm shift in material innovation.


Led by experts in the Centre for Materials Innovation and Future Fashion (CMIFF), the research team emphasizes the accessibility and affordability of nanodiamonds. Dr. Houshyar dispels misconceptions, highlighting the distinction between nanodiamonds and gem-grade diamonds, along with their cost-effectiveness compared to alternative carbon materials. This pioneering endeavor not only revolutionizes textile engineering but also underscores the transformative potential of nanotechnology in addressing contemporary challenges.
