The present technology relates to a method for manufacturing a polymer nanofoam material. The resulting material is light transmissive, impact resistant and ultra-insulating, and sound-insulating, lightweight foam. The dielectric properties of the foam are very special. If used in insulated glass in the future, only North America can save 20 billion US dollars in energy costs per year.

At the moment the most challenging problem of nanocellular foam is to produce a foam with cell size less than 100 nm and with a relative density less than 0.3.  We prepared a nanceolluar foam with a pore size of 30 ~ 40 nm and the relative density is around 0.25. The foamed material is translucent and the physical properties of the foam are very different.

According to the research of the Argonne National Laboratory, the use of transparent nanofoam will save 20 billion US dollars of energy and 110 million tons of carbon dioxide emissions per year. Nanocellular material also has great potential in other uses such as biomedical material, optoelectronic materials, and filtration, etc.
