Background Art
Background Art
[2] Most commercially important polymers today are entirely synthetic and produced in high volume on appropriately scaled organic synthetic techniques. Synthetic polymers today find application in nearly every industry and area of life. Polymers are widely used as matrix in sensing membrane and separation membrane in fuel cell. Polymers exhibit a wide range of mechanical properties, i.e., elasticity, hardness, brittleness, temperature stability, chemical resistance, and optical characteristics.
[3] The most common ion selective electrode construction requires an ion-selective
membrane of polymeric type containing ionophore for molecular recognition. The most commonly employed polymeric sensing matrix is poly(vinyl chloride) or PVC. However, there are reports on problems in fabricating solid-state sensors with this polymer. Apparently PVC exhibits poor adhesion towards ion-selective electrode. Moreover, PVC requires the use of plasticizer for the purpose of softening the polymer. Plasticizer leaching results in degradation of sensor performance and shortens the lifetime of the chemical sensor. The problem is more serious for in vivo applications, wherein the plasticizer molecules from leaching can cause inflammation and toxicity to the surrounding tissues.

Detailed description of the preferred embodiment
The present invention provides a method for preparation of bulk polymeric membrane that shows good characteristics as sensing material, as well as for other applications such as fuel cell. Different ratios of methyl methacrylate (1) and tetrahydrofurfuryl acrylate (2) monomers afford bulk polymeric membrane called MT membrane (3) under reflux condition in benzene or toluene in the presence of benzoyl peroxide. The proposed bulk membrane offers economic benefits of low costs of the monomers as well as and its ease of handling.
Other benefits of MT copolymer membrane include low impedance due to polar tetrahydrofurfuryl substituent, compatibility with sensor components, biocompatiblity and minimal health hazard.
An important characteristic of a polymer is its glass transition temperature, Tg. When a polymer is cooled below this temperature, it exists in solid form. Polymers like poly(methyl methacrylate) are hard and brittle having high glass transition temperatures, with Tg i.e. well above 100°C. On the contrary polymers like polytetrahydro- furfuryl acrylate are sticky liquid with glue characteristics and very low Tg. Mixing methyl methacrylate (1) and tetrahydrofurfuryl acrylate (2) with appropriate ratio of the monomers in bulk polymer process can result in copolymer with desired characteristics for sensor and fuel cell applications.
The copolymer membranes of the invention are fabricated from methyl methacrylate (1) and tetrahydrofurfuryl acrylate (2) monomers. The disclosed copolymer exhibits excellent properties as a sensing membrane that includes clear and colorless appearance, good flexibility, not sticky, and good adhesion onto surface. The polarity of these copolymer can be varied depending on the ratio of the methyl methacrylate (1) and tetrahydrofurfuryl acrylate (2) monomers , and thus can be used to fabricate sensing membrane with 'tailored polarity' .
The invention now being generally described, the same will be better understood by reference to the following detailed examples which are provided for purposes of illustration only and are not to be limiting of the invention unless so specified.
Examples
The present invention is further described in the following examples and the co- polymerization reaction is shown in Figure 3;
[39] Example 1
[40] Preparation of Bulk Co-polymer Methyl Methacrylate-Tetrahydrofurfuryl Acrylate (Bulk MT55)
[41] Put 5 mL methyl methacrylate (MMA)(1) and 5 mL tetrahydrofurfuryl acrylate
(THFA)(2) monomers into 50 mL three-neck round bottom flask. Add 15 mL benzene and 1 mg benzoyl peroxide as initiator into the mixture of monomers.. Start the reflux process with maintained at 95°C while stirring under nitrogen gas flow for 7 hours. After 7 hours the heating was discontinued and the mixture gradually cooled to room temperature. Then the viscous polymeric material was transferred to a 50 mL beaker, and the solid material becomes cloudy. The cloudy polymeric material was washed three times with 5 mL portions of petroleum ether (80°C-100°C) until it becomes clear. The bulk polymeric membrane was air dried at ambient condition over night. The final solid mass appears white and elastic as shown in Figure 4.
[42] Example 2
[43] Magnesium Sensor based on Bulk Methyl Methacrylate-Tetrahydrofurfuryl
Acrylate Copolymer Membrane (Bulk MT 55)
[44] 1. (i) Inner Layer Preparation D
[45] 1 g of 2-hydroxylethyl methacrylate (Hema) monomer is mixed with 0.016 g of pho- toinitiator 2,2-dimethoxyl-2-phenylacetopenone (DMPP) and dropped onto Ag/AgCl electrode surface . The mixture was photocured under UV radiation in UV-exposure unit under constant flow of nitrogen gas for 3 minutes. The polymer film formed was then hydrated with 0.1 M of Magnesium Chloride solution for 10 minutes to form the inner layer of the sensor.

The mixture was dissolved with 500 uL tetrahydrofuran (THF) and sonicated for 30 minutes. 10 uL part of the mixture was dropped on top of the freshly prepared and hydrated inner layer and dry under room temperature and open air. Further, the magnesium ion selective electrode was tested versus a commercial Ag/AgCl double junction reference electrode. The results were shown in Table 1 and Figure 5.
