Abstract: A heat insulating material includes an aerogel that has macro-pores and meso-pores. A method for manufacturing a heat insulating material, including: a sol preparation step of adding a gelling agent into sodium silicate such that a molar ratio of the gelling agent relative to NaO2 is 0.1 to 0.75, and adjusting a sol into which macro-pores are introduced by leaving unreacted Na and non-cross-linked oxygen in a siloxane skeleton; an impregnating and gelling step of impregnating a nonwoven fabric fiber structure with the sol to form a composite of hydrogel-nonwoven fabric fiber; a hydrophobizating step of mixing the formed composite of hydrogel-nonwoven fabric fiber with a silylating agent to modify a surface thereof; and a drying step of removing a liquid contained in the surface modified composite of hydrogel-nonwoven fabric fiber by drying under a temperature and pressure lower than respective critical values.

Abstract: The invention uses a dispersion (303) of suspended single-layer graphene (201), multilayer graphene (202), and graphite (203), and applies a magnetic field to the dispersion (303) to separate the single-layer graphene (201) from the dispersion (303). In the magnetic field applying step of the graphene producing method, the single-layer graphene (201), the multilayer graphene (202), and the graphite (203) are situated at different locations in solvent by using the difference in the diamagnetism strengths of the single-layer graphene (201), the multilayer graphene (202), and the graphite (203).

Abstract: A dispersion of suspended single-layer graphene, multilayer graphene, and graphite is used. A magnetic field is applied to the dispersion to separate the single-layer graphene from the dispersion. By applying the magnetic field, the single-layer graphene, the multilayer graphene, and the graphite are situated at different locations in solvent by the difference in the diamagnetism strengths of the single-layer graphene, the multilayer graphene, and the graphite.
