Method for producing dried solid, and dried solid

Abstract

Provided is a dried solid including a composite having heat-ray absorption properties, and a method for producing the dried solid, the dried solid allowing the composite to be redispersed in water, the redispersed composite to exhibit excellent heat-ray absorption properties. The method for producing a dried solid including a composite including a sulfated polysaccharide and polythiophene, includes: separating a solid phase from a dispersion of the composite including the sulfated polysaccharide and the polythiophene; and drying the solid phase to obtain the dried solid having a moisture content of 15 wt % or more.
