発明の名称 (英語) COMPOSITE MATERIAL, GAS ADSORBENT AND METHOD FOR PRODUCING COMPOSITE MATERIAL UPDATE 新技術説明会
発明の概要(英語) A composite material which comprises a porous coordination polymer compound (PCP) and a porous body that has pores inside, and which is characterized in that: the porous body has a network structure of Si-O bonds obtained by copolymerizing a dialkoxysilane and a trialkoxysilane; and the porous coordination polymer compound is supported within the pores of the porous body. A method for producing a composite material comprising a porous coordination polymer compound and a porous body that has pores inside, which is characterized in that: the porous body has a network structure of Si-O bonds obtained by copolymerizing a dialkoxysilane and a trialkoxysilane; and the porous coordination polymer compound is supported within the pores of the porous body by the intermediary of a solvent.
従来技術、競合技術の概要(英語) BACKGROUND ART
Porous coordination polymer compound (Porous Coordination Polymer: PCP) is, the metal ion and organic ligands coordinated to form a three-dimensional network porous body and having a nanopore, a regular pore structure and high specific surface area, such as a flexible structure comprising a variety of characteristics. Therefore, the PCP, designed as a highly functional material and it is expected that the role of, for example, gas adsorbent material such as gas storage and is currently under development to applications.
It is preferable for the practical implementation of the PCP, PCP shaping technique is essential. Conventional, PCP excipients as technology, several methods have been known. For example, in Non-Patent Document 1, the macro pores within the pores of the silica monolith having the PCP is obtained by synthesizing the complex is disclosed. PCP is in this document, 'Cu-BTC' (i.e., cu3 (BTC)2 (in this case, BTC is 1, 3, 5 - benzenetricarboxylic acid) ) have been used, the composite Cu-BTC-SiO2 monolith has been described.
In addition, in Non-Patent Document 2, the precursor solution of the silica aerogel was previously adjusted (Cu-BTC) is mixed with the PCP, gelation of the resulting composite is disclosed. PCP is in this document, in the same manner as the non-patent document 1 'Cu-BTC' have been used, the silica, tetraethyl orthosilicate (TEOS) can be synthesized from been described.
Further, in the non-patent document 3, and PCP and bentonite clay paste obtained by compaction molding the composite has been disclosed. PCP is in this document, 'MIL-101 (Cr) ' (that is, Cr3 O(OH) (-H2 O)2 (BDC)3, xH2 O(here, the BDC 1,4 - dicarboxylic acid) ) is used.
In addition, in Non-Patent Document 4, polytetrafluoroethylene (PTFE) as a binder containing 3wt % of nickel metal foam PCP suspension can be sprayed, coated with the nickel metal skeleton PCP disclosed composite materials. PCP is in this document, in the same manner as the non-patent document 3 '(Cr) MIL-101' is used.
On the other hand, conventionally, one or more of the functional group 2 and a copolymer of alkoxysilane, marshmallows called gel has been known a flexible material. For example, to Patent Document 1, an alkoxysilane compound having a specific partial structure of the copolymer and is disclosed, a metal ion chelate silica xerogel embodiment is used as the material removal has been described.
