▪Porous materials are defined as the structures with a number of pores, and they are classified with nanoporous, mesoporous, and macroporous materials according to the size of the pores. In our laboratory, various porous materials are synthesized by chemical reaction, spray drying, and electrospinning to apply sound absorber, thermal insulator, catalytic supports, adsorbents, and superhydrophobic coatings

▪The extraction of source component like sodium silicate for porous materials is also underway from biowastes like rice husk.
