The present invention provides, for example, a silicone porous body having a porous structure with less cracks and a high proportion of void space as well as having a strength. The silicone porous body of the present invention includes silicon compound microporous particles, wherein the silicon compound microporous particles are chemically bonded by catalysis. For example, the abrasion resistance measured with BEMCOT is in the range from 60% to 100%, and the folding endurance measured by the MIT test is 100 times or more. The silicone porous body can be produced, for example, by forming the precursor of the silicone porous body using sol containing pulverized products of a gelled silicon compound and then chemically bonding the pulverized products contained in the precursor of the silicone porous body. The chemical bond among the pulverized products is preferably a chemical crosslinking bond among the pulverized products, for example.

Melamine Formaldehyde (MF) photonic cooling bulk is disclosed for covering outer surfaces of a building. The MF photonic cooling bulk comprises a mass of hydraulically pressed MF microparticles that has been thermally annealed to form a fire and corrosion-resistant, cross-linked photonic cooling bulk configured to reflect incident solar irradiation and radiate heat from the building to the outer space.

Polymer composite materials are disclosed containing one or more chemical scavengers. The polymer composites are porous and are configured to be contacted with a liquid for removing trace amounts of metals, proteins, polypeptides, polyphenols, other organic compounds, and the like. In order to produce the porous composite polymer product, one or more chemical scavengers are combined with thermoplastic polymer particles and sintered into a shape. The polymer particles act as a binder trapping or encasing the one or more chemical scavengers in the porous structure.
