At the University of Maryland (UMD), a team led by Po-Yen Chen, an associate professor in the Department of Chemical and Biomolecular Engineering, has made strides in advancing the development of materials for green technologies. They have achieved this by unveiling a novel method that accelerates the production of aerogel materials through the integration of machine learning and collaborative robotics. This method holds promise for use in wearable heating devices, and their findings have been published in the journal Nature Communications.
Aerogels, lightweight and porous materials, mimic the composition of water-based gels but are created using air instead, hence their unique mechanical strength and flexibility. These properties render aerogels excellent for thermal insulation and wearable applications. Traditionally, producing aerogels has been challenging due to the complexity and labor-intensiveness of the design and experimentation process.
To address these complexities, UMD engineers have combined robotics, machine learning algorithms, and material science expertise. This synergistic approach significantly speeds up the creation process of aerogels with programmable mechanical and electrical characteristics and boasts an impressive 95% accuracy in predicting sustainable product performance.
The research team has leveraged conductive titanium nanosheets and natural components such as cellulose and gelatin to produce sturdy and flexible aerogels. Po-Yen Chen highlights that the integration of robotics and machine learning not only improves the caliber and pace of data collection but also navigates the intricate design landscape more effectively.
Moreover, the team envisions the potential expansion of their tool for tackling various challenges, including environmental management and sustainable energy storage solutions like insulative windows. With plans to explore unique mechanical, thermal, and electrical properties for aerogels, university researchers like Eleonora Tubaldi aim to produce materials suited for demanding environmental conditions.
The upcoming research by Chen’s group will delve into understanding the microstructures responsible for the aerogels’ durability and flexibility, pushing the boundaries of material innovation for various applications in green technology.
