Abstract: Provided are a composition for swelling pretreatment of a cured thermosetting resin material before decomposition, including a surfactant and an acidic material, and a method for swelling pretreatment of a cured thermosetting resin material before decomposition by using the same. When carrying out swelling pretreatment of a cured thermosetting resin material before decomposition by using the composition, it is possible to accelerate infiltration of the acidic material into the cured thermosetting resin material and swelling of the cured thermosetting resin material by virtue of the surfactant, and thus to increase the decomposition reactive surface area. Therefore, it is possible to increase reaction efficiency during the subsequent decomposition process, and to increase the decomposition ratio during the same period of time.

Abstract: Prepared is a halogenated carbon material, which reduces a carbon material having an oxygen-based functional group by introducing a halogen gas or a mixed gas of a halogen gas and an inert gas into the carbon material having an oxygen-based functional group, and dopes a halogen into the carbon material. The resulting halogenated carbon material includes one or more selected from a group consisting of C—Y2 and C—Y3, and may be suitably for an energy device such as a fuel cell, a lithium ion battery, and a solar cell.

Abstract: For depolymerization of a cured epoxy resin material, used is a composition including a transition metal salt or a transition metal oxide containing a transition metal element (metal element that belongs to Groups 3-12 in the Periodic Table). In the reaction solvent, an oxidation occurs by the medium of the transition metal element so that the cured epoxy resin material may be depolymerized and decomposed. In this manner, it is possible to carry out depolymerization of a cured epoxy resin material at a temperature of 200° C., specifically 100° C. or lower very simply and rapidly, and to reduce the processing cost and energy requirement.

Abstract: A cured epoxy resin material is depolymerized by using a composition including a compound represented by the chemical formula of XOmYn (wherein X is hydrogen, alkali metal or alkaline earth metal, Y is halogen, m is a number satisfying 1≤m≤8 and n is a number satisfying 1≤n≤6), and a reaction solvent, wherein X is capable of being dissociated from XOmYn and Y radical is capable of being produced from XOmYn in the reaction solvent. It is possible to carry out depolymerization of a cured epoxy resin material, for example, at a temperature of 200° C., specifically 100° C. or lower, and to reduce processing cost and energy requirement. It is also possible to substitute for a reaction system using an organic solvent as main solvent, so that the contamination problems caused by the organic solvent functioning as separate contamination source may be solved and environmental contamination or pollution may be minimized.

Abstract: Provided is an aerogel-containing heat insulation composite obtained by providing a volatile material to the pores of the aerogel, blending the aerogel with a polymer resin, particularly a flexible polymer resin, to form a composite, and removing the volatile material. Thus, it is possible to prevent a decline of the porosity of the aerogel caused by infiltration and impregnation of the pores of the aerogel with the resin. As a result, the aerogel-containing heat insulation composite, particularly containing a high content of aerogel, may retain the heat insulation property of the aerogel as well as the flexibility of the plastic material.

Abstract: A cured epoxy resin material is depolymerized by using a composition including a compound represented by the chemical formula of XOmYn (wherein X is hydrogen, alkali metal or alkaline earth metal, Y is halogen, m is a number satisfying 1≦m≦8 and n is a number satisfying 1≦n≦6), and a reaction solvent, wherein X is capable of being dissociated from XOmYn and Y radical is capable of being produced from XOmYn in the reaction solvent. It is possible to carry out depolymerization of a cured epoxy resin material, for example, at 200° C., specifically 100° C. or lower, and to reduce a processing cost and an energy requirement. It is also possible to substitute for a reaction system using an organic solvent as main solvent, so that the contamination problems caused by the organic solvent functioning as separate contamination source may be solved and environmental contamination or pollution may be minimized.
Abstract translation: 固化的环氧树脂材料通过使用包含由化学式XOmYn表示的化合物的组合物（其中X是氢，碱金属或碱土金属，Y是卤素，m是满足1≤m≤8且n 是满足1≤n≤6的数），并且其中X能够从XOmYn和Y自由基解离的反应溶剂能够在反应溶剂中由XOmYn产生。 例如可以在200℃，特别是100℃以下进行固化环氧树脂材料的解聚，降低加工成本和能量需求。 也可以用有机溶剂作为主要溶剂代替反应体系，从而可以解决有机溶剂作为单独的污染源发挥的污染问题，并且可以使环境污染或污染最小化。
