| Summary: | 碩士 === 南台科技大學 === 化學工程與材枓工程系 === 101 === In this study, We develop a new composite materials combined with PANi and chlorophyll by the chemical synthesis, chlorophyll can excite an electron from light absorption and transfers the generated electronic to the polyaniline. When the molar addition of APS is as high as 1.75-fold to that of aniline, chlorophyll characteristic absorption peaks vanished, which is observed both on UV-vis and FT-IR spectra. The low absorption of chlorophyll is due to the electromagnetic shielding effect by PANi. It is was not much difference by addition of initiator does not affect the patterns from FESEM surface morphology, but the pure polyaniline and chlorophyll / polyaniline are different of patterns significantly. When the initiator add more and more, we can get higher conductivity by the conductivity measurement.
MIPs concept chlorophyll to capture functional monomer methacrylic acid copolymer of aniline to join, the results can be learned not added aniline polymer in the UV-Vis spectra at 430nm and 660nm chlorophyll absorption peak planting, but with aniline add will find its peak significantly reduced, presumably the shell thickening leads to the relationship, it may be because polyaniline obscured the relationship between chlorophyll molecules is not easy to absorb photonsleaving the absorption reduced. The results of FT-IR can be seen leaving the number of functional groups are overlapping in judgment doubt, From SEM can know the chlorophyll be fixed with most of the spherical shape that chlorophyll polymer polymerized by adding a crosslinking agent. By UV-Vis and FT-IR, we can know that the coating amount increased with the concentration increase of chlorophyll, but by the SEM results can be seen with the TEM patterns unlike its complete spherical.
