Researchers develop nanowood that can be used as an insulator, according to a report published on March 13, 2018.
This insulator, developed by the research team who created see-through wood, is a cheaper and environmentally friendly insulator called as nanowood. When compared to Styrofoam and silica aerogels, nanowood insulates better. Tian Li, a researcher on the project said, “It is extremely promising to be used as energy efficient building materials.” Lignin and hemicellulose, two natural components of wood were removed to turn the wood to white color and reduce its ability to conduct heat.
In wood, conduction of heat can occur through the tubed structures through which water and nutrients are transported. However, heat does not properly conduct through those tube structures. After stripping away lignin and hemicellulose, lot of gaps are formed in the wood. Therefore, even less heat is conducted through the wood. Nanowood, apart from being an efficient insulator, is stronger and does not cause any lung irritations that are caused by fibers from glass wool insulators. According to the researchers, nanowood can be fabricated for US$ 7.44 per square meter.
It is biodegradable and will not contribute to landfill waste like other insulating materials. Liangbing Hu, an associate professor said, “We are reinventing ways to use wood that could be useful in constructing energy efficient and environmentally friendly homes.” This development is expected to increase the growth of Global High Performance Insulation Materials Market, as elaborated in the global high performance insulation materials market report published by Coherent Market Insights.
