BIFUNCTIONAL COMPOSITE MEMBRANE AND PREPARATION METHOD AND USE THEREOF, AND METHOD FOR REMOVING PLASTICIZER IN LIQUOR
The disclosure provides a bifunctional composite membrane, a preparation method and use thereof, and a method for removing a plasticizer in liquor. The bifunctional composite membrane includes a supporting membrane and a dense layer which covers a surface of the supporting membrane, wherein the supporting membrane includes a filtering membrane and an adsorbent, and the adsorbent is dispersed in a pore structure of the filtering membrane.
METAL ORGANIC FRAMEWORK, SEPARATION MEMBRANE, AND METHOD FOR PRODUCING METAL ORGANIC FRAMEWORK
The present invention provides a metal organic framework suitable for increasing a flux of a permeation fluid permeating through a separation membrane. The metal organic framework of the present invention includes a metal ion and an organic ligand. The organic ligand includes, besides a functional group to be coordinated with the metal ion, a first functional group and a second functional group different from the first functional group. The second functional group is a hydroxy group, a nitro group, or a carboxyl group. A ratio of the number of moles of the second functional group with respect to a total value of the number of moles of the first functional group and the number of moles of the second functional group is 30 mol % or less.
CARBON MATERIAL AND METHOD FOR PRODUCING CARBON MATERIAL
The present disclosure provides a carbon material including a carbon-containing layer having opening parts; and a solid body provided so as to cover the opening parts of the carbon-containing layer, in which the solid body has hole parts communicating with the opening parts.
Preparation of metallocene containing cationic polymers for anion exchange applications
Chemically inert, mechanically tough, cationic metallo-polyelectrolytes designed as durable anion-exchange membranes (AEMs) via ring-opening metathesis polymerization (ROMP) of cobaltocenium-containing cyclooctene with triazole as the only linker group, followed by backbone hydrogenation to provide a new class of AEMs with a polyethylene-like framework and alkaline-stable cobaltocenium cation for ion transport, which exhibit excellent thermal, chemical and mechanical stability, as well as high ion conductivity.
LIQUID METAL COMPLEX HAVING OXYGEN-ABSORBING ABILITY
To provide a liquid metal complex having an oxygen absorbing ability, containing a cobalt-acacen complex or a derivative thereof, and an ionic liquid in which an ionic ligand having an amine structure and a counter ion thereof are paired, in which the cobalt-acacen complex or the derivative thereof is expressed by general formula (1):
##STR00001##
and the liquid metal complex has a structure in which the amine structure of the ionic ligand is axially coordinated with a cobalt atom of the cobalt-acacen complex or the derivative thereof.
Carbon molecular sieve membranes containing a group 13 metal and method to make them
A carbon molecular sieve (CMS) membrane having improved separation characteristics for separating olefins from their corresponding paraffins is comprised of carbon with at most trace amounts of sulfur and a group 13 metal. The CMS membrane may be made by pyrolyzing a precursor polymer devoid of sulfur in which the precursor polymer has had a group 13 metal incorporated into it, wherein the metal is in a reduced state. The pyrolyzing for the precursor having the group 13 metal incorporated into it is performed in a nonoxidizing atmosphere and at a heating rate and temperature such that the metal in a reduced state (e.g., covalently bonded to carbon or nitrogen or in the metal state).
MIXED MATRIX MEMBRANE (MMM) AND METHOD OF USING MMM IN H2/CO2 GAS SEPARATION
M(SiF.sub.6)(pyz).sub.3 (M=Cu, Zn, Co, or Ni) has a pore size between a size of H.sub.2 and a size of CO.sub.2, and thus exhibits prominent screening performance for H.sub.2/CO.sub.2. A strong interaction between Cu(SiF.sub.6)(bpy).sub.2 and a CO.sub.2 molecule can hinder the transport of the CO.sub.2 molecule. The above two MOFs both can achieve the H.sub.2/CO.sub.2 separation. By preparing a dense MSiF.sub.6/polymer layer, MSiF.sub.6 is uniformly dispersed in the polymer and is fixed, and subsequently, MSiF.sub.6 is converted into M(SiF.sub.6)(pyz).sub.3 or Cu(SiF.sub.6)(bpy).sub.2 by interacting with an organic ligand. Through vapor-induced in-situ conversion, MOF particles can be well dispersed without interface defects between the MOF particles and the polymer. Even at a doping amount of 80%, the mechanical flexibility and stability of the MMM can still be retained.
Adsorption-enhanced and plasticization resistant composite membranes
The disclosure provides for polymer membranes which comprise metal organic frameworks, methods of making therein, and methods of use thereof, including in gas separation.
PREPARATION OF METALLOCENE CONTAINING CATIONIC POLYMERS FOR ANION EXCHANGE APPLICATIONS
Chemically inert, mechanically tough, cationic metallo-polyelectrolytes designed as durable anion-exchange membranes (AEMs) via ring-opening metathesis polymerization (ROMP) of cobaltocenium-containing cyclooctene with triazole as the only linker group, followed by backbone hydrogenation to provide a new class of AEMs with a polyethylene-like framework and alkaline-stable cobaltocenium cation for ion transport, which exhibit excellent thermal, chemical and mechanical stability, as well as high ion conductivity.
