- the metallosiloxane represented by Formula 2 can be prepared from any compound having a siloxyl group. Because the distance from the central metal to oxygen atoms is longer than usual covalent bonds, the binding force between them is relatively weak. Accordingly, the bond between the metal and oxygen is relatively easily dissociated by heat, and an acid or base, to give the metallosiloxane ion repressed by Formula 3 according to Scheme 1 below. [Scheme 1]
- the metallic oxide (M 2 0) is present in the form of particles.
- the process of Scheme 2 occurs at the surface of a metallic oxide (M 2 0) particle and the resultant metallosiloxane-metallic oxide compound has a structure shown in FIG. 1. Since the metallosiloxane-metallic oxide compound of the invention is present in the form of particles and is used in a powder form, a means to fix the particles or powders is required. In the present invention, woven or non-woven fabric may be used to fix the metallosiloxane-metallic oxide compound.
- the metallosiloxane-metallic oxide compound powder is coated on woven or non-woven fabric to a predetermined thickness and another woven or non-woven fabric is laminated thereon.
- a lamination membrane in which metallosiloxane-metallic oxide compound powder layer(s) is formed between the woven or non-woven fabric is obtained.
- the lamination membrane itself can be used as an oxygen enriching membrane. Also, it can be laminated along with other lamination membranes to be described later as oxygen enriching membranes.
- separation of a gaseous mixture through a porous membrane can be explained by the following four principles. First, Knudsen diffusion occurs when the pore size is smaller than the mean free path of a specific gas molecule. Second, surface diffusion occurs by interaction with the pore surface. Third, capillary diffusion occurs by condensation of a specific liquid.
- FIG. 2 is a schematic diagram for illustrating the pendant model. According to the pendant model, a plurality of metallosiloxane units protruding inside the pore move freely like cilia.
- the metallosiloxane units align almost vertically to the direction of the pore, as seen in FIG. 2 (a). If the pressure is relatively high, the metallosiloxane units align almost parallel to the direction of the pore, as seen in FIG. 2 (b).
- the oxygen enriching membrane of the present invention not only offers superior oxygen selectivity and permeability even with a low pressure difference, but also has good strength and is not easily torn thanks to the lamination membrane structure. Also, since it is prepared by fixing the metallosiloxai e-metallic oxide compound in the powder form on woven or non-woven fabric and laminating them repeatedly, membranes with uniform pore size can be produced in large amounts.
- the metallosiloxane unit moves freely, so that superior permeability and selectivity are obtained even at low pressure. Since the compound having 4 to 1000 siloxane units, the m and n values in Formula 1 , is suspended and fixed to the metallic oxide (M 2 0), it offers good oxygen enriching performance even with a low pressure difference by the pendant model. Besides laminating the metallosiloxane-metallic oxide compound powder, a method of dissolving the metallosiloxane compound in a polymerization monomer and polymerizing the monomer to obtain a membrane is practicable. The metallosiloxane represented by Formula 2 dissolves well in most monomers of matrix polymer resins.
- the metallosiloxane After dissolving the metallosiloxane in a monomer of a matrix polymer resin to an adequate concentration, it is stirred sufficiently and the monomer is polymerized. Then, a polymer is obtained in which the metallosiloxane is uniformly distributed in the matrix. The resultant matrix polymer is coated on woven or non-woven fabric to obtain a lamination membrane. The resultant lamination membrane can act as an oxygen enriching membrane. Also, it is possible to prepare a membrane using an air-permeable foaming agent. That is, the metallosiloxane is added to a polymer which has not yet solidified just after polymerization. The polymer is stirred so ⁇ that the metallosiloxane is dispersed uniformly.

Description
METALLOSILOXANE-METALLIC OXIDE COMPOUND, OXYGEN ENRICHING MEMBRANE COMPRISING METALLOSILOXANE, AND METHOD FOR PREPARING THE SAME
BACKGROUND OF THE INVENTION
(a) Field of the Invention The present invention relates to an oxygen enriching membrane which selectively increases oxygen content in the air, and a method for preparing the same, and more particularly to an oxygen enriching membrane having superior oxygen permeability and selectivity while maintaining superior mechanical strength, and a method for preparing the same.
(b) Description of the Related Art The air we breathe consists of about 20.9% of oxygen and about 78.1 % of nitrogen. A membrane that is selectively more permeable to oxygen than nitrogen in the air is called the oxygen enriching membrane. Air passing through the oxygen enriching membrane has a relatively higher oxygen content. Accordingly, the oxygen enriching membrane can improve fuel efficiency of internal combustion engines of vehicles, contributing to energy saving. Also, it can be widely used in the fields of medicine, oxidation processing, and environmental engineering which do not require high-level oxygen content. Also, since enriched nitrogen is simultaneously obtained accompanied with oxygen enrichment, the oxygen enriching membrane can i
be utilized in the fields requiring nitrogen-rich environment, e.g., fermentation processes. Using the oxygen enriching membrane, it is possible to separate gas with a simple apparatus. Thus, it is not limited in place or mobility. Since the 1980s, gas separation using membranes has undergone a lot of developments. Although membrane separation is inadequate for obtaining massive oxygen at a high concentration, compared with the freezing method it has drawn a lot of attention recently since it consumes less energy during the separation process. Since Kammermeyer first used silicone rubber for separation of gas in 1957 (K. Kammermeyer, Ind. Eng. Chem., 49, 1685, 1957), methyl-based polysiloxanes have been known to be superior to any other polymers in oxygen permeation properties until the advent of polytrimethylsilylpropyne (R. L. Riley et al., USP 4,243,701 ). However, if the membrane was made thin to improve oxygen permeability, it was torn easily. There was a need to solve this problem. The first commercially successful oxygen enriching membrane was one having improved membrane strength through copolymerization of siloxane and carbonate (see W. J. Ward III, J. Membrane Sci., 1 , 99, 1976). In this regard, research was performed using a graft copolymer of styrene and dimethylsiloxane, introducing an amide into the main chain using tetramethyldisiloxane and aliphatic dicarboxylate, substituting a variety of siloxanes at the para position of polystyrene, and so forth (see Y. Kawakami, J. Polym. Sci., Part A, 25, 1591 , 1987).
Fluorine-substituted derivatives were also used as oxygen enriching membranes. This was because the higher the content of fluorine atoms, the higher the solubility of gaseous oxygen. Yoshio et al. synthesized a poly(phenylacetylene) derivative having a trifluoromethyl in the benzene ring to prepare an oxygen enriching membrane having an oxygen selectivity over nitrogen of 2.1 (see Y. Hayakawa, M. Nishida, T. Aoki, and H. Muramatsu, J. Polym. Sci., Part A, 30, 873, 1992). Paul et al. synthesized tetra-halogenated polycarbonates in which four hydrogen atoms of bisphenol A were substituted with halogen atoms, such as chlorine and bromine, to prepare oxygen enriching membranes having an oxygen selectivity over nitrogen of 6.37 and 7.47 (see D. R. Paul, J. Membrane Sci., 34, 185, 1987). However, in spite of these efforts, oxygen permeability tends to decrease as oxygen selectivity over nitrogen increases. Oxygen permeability can be improved by increasing a pressure difference across the membrane, but then a lot of energy is required to separate the oxygen. Korean Patent Publication No. 2001-0018930 disclosed a cellulose-based oxygen enriching membrane which is not torn easily, sacrificing neither oxygen selectivity nor oxygen permeability. However, it is limited in oxygen selectivity and permeability because of the structural limit of cellulose. In addition, it is inadequate for mass production, since an activation process is necessary to loosen the cellulose structure. SUMMARY OF THE INVENTION It is an object of the present invention to provide a
metallosiloxane-metallic oxide compound for improving oxygen permeability and selectivity of an oxygen enriching membrane. It is another object of the invention to provide an oxygen enriching membrane having superior oxygen permeability and selectivity, and that is not torn easily and has good strength. It is still another object of the invention to provide a method for preparing the metallosiloxane-metallic oxide compound. It is further another object of the invention to provide a method for preparing the oxygen enriching membrane. To attain the objects, the present invention provides a metallosiloxane-metallic oxide compound represented by Formula 1 below. The invention also provides an oxygen enriching membrane comprising the metallosiloxane-metallic oxide compound, and a metallosiloxane compound represented by Formula 2 below or a mixture thereof.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereunder is given a more detailed description of the present invention. The metallosiloxane represented by Formula 2 can be prepared from any compound having a siloxyl group. Because the distance from the central metal to oxygen atoms is longer than usual covalent bonds, the binding force between them is relatively weak. Accordingly, the bond between the metal and oxygen is relatively easily dissociated by heat, and an acid or base, to give the metallosiloxane ion repressed by Formula 3 according to Scheme 1 below. [Scheme 1]
The metallosiloxane ion readily reacts with a metal oxide particle to give the metallosiloxane-metallic oxide compound represented by Formula 1 according to Scheme 2 below. [Scheme 2]
The metallic oxide (M20) is present in the form of particles. The process of Scheme 2 occurs at the surface of a metallic oxide (M20) particle and the resultant metallosiloxane-metallic oxide compound has a structure shown in FIG. 1. Since the metallosiloxane-metallic oxide compound of the invention is present in the form of particles and is used in a powder form, a means to fix the particles or powders is required. In the present invention, woven or non-woven fabric may be used to fix the metallosiloxane-metallic oxide compound. The metallosiloxane-metallic oxide compound powder is coated on woven or non-woven fabric to a predetermined thickness and another woven or non-woven fabric is laminated thereon. If this process is repeated at least once, a lamination membrane in which metallosiloxane-metallic oxide compound powder layer(s) is formed between the woven or non-woven fabric is obtained. The lamination membrane itself can be used as an oxygen enriching membrane. Also, it can be laminated along with other lamination membranes to be described later as oxygen enriching membranes. In general, separation of a gaseous mixture through a porous membrane can be explained by the following four principles. First, Knudsen diffusion occurs when the pore size is smaller than
the mean free path of a specific gas molecule. Second, surface diffusion occurs by interaction with the pore surface. Third, capillary diffusion occurs by condensation of a specific liquid. Fourth, in a molecular sieve, the pore acts as a sieve that passes only the molecules smaller than the pore size. In non-porous membranes, it can be explained by dissolution of gas at the membrane surface and penetration by diffusion. Here, solubility of oxygen to the membrane and degree of diffusion are important factors. Adding to these, the pendant model was proposed to explain the peculiar characteristics of the oxygen enriching membrane (Jaejin Hong, Research on gas separation of siloxylcellulose membrane, Dankook University, Thesis for doctorate, 1998). FIG. 2 is a schematic diagram for illustrating the pendant model. According to the pendant model, a plurality of metallosiloxane units protruding inside the pore move freely like cilia. When the pressure applied to the oxygen enriching membrane is relatively low, the metallosiloxane units align almost vertically to the direction of the pore, as seen in FIG. 2 (a). If the pressure is relatively high, the metallosiloxane units align almost parallel to the direction of the pore, as seen in FIG. 2 (b). The oxygen enriching membrane of the present invention not only offers superior oxygen selectivity and permeability even with a low pressure difference, but also has good strength and is not easily torn thanks to the lamination membrane structure. Also, since it is prepared by fixing the metallosiloxai e-metallic oxide compound in the powder form on woven or non-woven fabric and laminating them repeatedly, membranes with uniform
pore size can be produced in large amounts. Also, differently from cellulose, the metallosiloxane unit moves freely, so that superior permeability and selectivity are obtained even at low pressure. Since the compound having 4 to 1000 siloxane units, the m and n values in Formula 1 , is suspended and fixed to the metallic oxide (M20), it offers good oxygen enriching performance even with a low pressure difference by the pendant model. Besides laminating the metallosiloxane-metallic oxide compound powder, a method of dissolving the metallosiloxane compound in a polymerization monomer and polymerizing the monomer to obtain a membrane is practicable. The metallosiloxane represented by Formula 2 dissolves well in most monomers of matrix polymer resins. After dissolving the metallosiloxane in a monomer of a matrix polymer resin to an adequate concentration, it is stirred sufficiently and the monomer is polymerized. Then, a polymer is obtained in which the metallosiloxane is uniformly distributed in the matrix. The resultant matrix polymer is coated on woven or non-woven fabric to obtain a lamination membrane. The resultant lamination membrane can act as an oxygen enriching membrane. Also, it is possible to prepare a membrane using an air-permeable foaming agent. That is, the metallosiloxane is added to a polymer which has not yet solidified just after polymerization. The polymer is stirred so π
that the metallosiloxane is dispersed uniformly. Then, an air-permeable foaming agent is added to obtain a polymer foam having numerous micropores. If the polymer foam is processed into a membrane, it can act as an oxygen enriching membrane. Hereinafter, the present invention is described in further detail through examples. However, the following examples are only for the understanding of the invention and the invention is not limited to or by the following examples.
