碩士 / 中原大學 / 化學研究所 / 104 / In this thesis, a series of polyaniline (PANI) derivatives were polymerized onto the melamine sponge, followed by applied in oil/water separation. First of all, the PANI and its derivative ware synthesized by conventional oxidative polymerization of corresponding monomer with ammonium persulfate as oxidant in 1.0 M HCl aqueous solution. The as-prepared melamine sponge modified with PANI, polyn-ethylaniline and polyfluoroaniline can be obtained and following by characterized by FTIR spectroscopy and SEM observation.
Upon the SEM observation, the pure melamine was found to reveal smooth surface. However, the melamine sponge modified with all three PANI derivatives were found to exhibit rough surface. The hydrophobic character of modified melamine sponge was determined by static contact angle of water droplets (CAWD). It should be noted that the melamine sponge modified with polyfluoroaniline was found to show the highest hydrophobic character as compared to its counterpart.
Finally, melamine sponge modified with PANI derivatives were used to apply in oil/water separation and adsorption of organic solvents. It should be noted that the polyfluoroaniline was found to display better oil/water separation and adsorption of organic solvent based on a series of systematically studies.
