Embodiment 1
[0156] Example 1: Using cationic polymerization initiator 2,2'-azobis(2-(1,3-dimethyl-4,5-dihydro- Synthesis of 1H-imidazol-3-ium-2-yl)) propane trifluoromethanesulfonate (ADIP) in polystyrene
[0157]Styrene (11.5 mL, 100 mmol, purchased from Sigma Aldrich Company) was charged into the reaction tube. Next, the cationic polymerization initiator 2,2'-azobis(2-(1,3-dimethyl-4,5-dihydro-1H-imidazol-3-ium-2-yl))propane Trifluoromethanesulfonate (ADIP) (0.607g, 1mmol), purified water (1mL, using Merck Direct-Q UV3), and isopropanol (12mL) were mixed, and the mixed solution was added to a styrene-filled in the reaction tube. The reaction tube was closed with a rubber stopper, and stirred in an oil bath at a temperature of 40° C. for 3 hours to polymerize the reaction mixture. The reaction mixture after the polymerization reaction was reprecipitated with methanol (3 L), and the precipitated polymer was washed twice each with purified water and methanol. The washed precipitated...
Embodiment 2
[0158] Example 2: Production of Polystyrene Membrane Using Cationic Terminated Polystyrene (Cation PS)
[0159] Commercially available polystyrene (polystyrene, manufacturing number 430102, weight average molecular weight = about 192,000, available from Sigma Aldrich) was used as a mixed material for verifying the effectiveness of cationic-terminated polystyrene (cationic PS). Mix cationic-terminated polystyrene (cationic PS) and the above-mentioned commercially available polystyrene in a prescribed weight ratio (5:5, 3:7, or 0:10, that is, cationic-terminated polystyrene (cationic PS) ) content of 50% by mass, 30% by mass, or 0% by mass) were mixed, tetrahydrofuran (6 mL) was added to these mixtures, and the mixture was stirred at 300 rpm at 50° C. for about 2 hours. After stirring, these mixtures were poured onto polytetrafluoroethylene (PTFE) plates and dried at room temperature for about 12 hours. After drying, the obtained film was pulverized and vacuum-dried at 180° C...
Embodiment 3-1
[0167] Embodiment 3-1: Utilize the antimicrobial property test of the polystyrene film synthesized by ADIP
[0168] The antimicrobial property test of the polystyrene film was implemented in accordance with JIS Z 2801:2000 antimicrobial processed product-antimicrobial property test method. As the strains tested in the antimicrobial test, Staphylococcus aureus (Staphylococcus aureus subsp. aureus NBRC 12732) and Escherichia coli (Escherichia coli NBRC 3972) were used. As the polystyrene film to be tested, the polystyrene film and the cationic terminal polystyrene (cationic PS) prepared in Example 2 having a content rate of 50% by mass of cationic terminal polystyrene (cationic PS) were used. ) content rate of 0% by mass of polystyrene film. In addition, as a comparative control, a commercially available polyethylene film was used for the test. These polystyrene films or polyethylene films were cut out to a size of 5 cm square, and the antimicrobial property test was carried...
