本研究是以化學合成法將聚苯胺與葉綠素做結合開發新型複合材料,以葉綠素吸收光激發產生電子,再以聚苯胺當介質將電子導出。當過硫酸銨添加到1.75倍時由UV-Vis和FT-IR發現葉綠素的吸收峰值以及官能基明顯的降低,可能是因為隨著起過硫酸銨的增加造成殼層變厚且聚苯胺有電磁波遮蔽的效果而使葉綠素不易吸收波長而產生這樣的現象。由FE-SEM觀察表面型態並無太大差異,由此得知起始劑的添加不會影響型態,但純聚苯胺和葉綠素/聚苯胺其型態上有明顯的不同;由導電度的測量可以發現當起使劑的量越多時其導電度越高。
利用分子拓印的概念以功能性單體甲基丙烯酸來抓取葉綠素,再以共聚物的方式將苯胺加入其中,由結果可以得知未添加苯胺的聚合物在UV-Vis圖譜上於430nm和660nm有葉綠素主要的吸收峰植,但隨著苯胺的添加會發現其峰值明顯的降低,推測可能是殼層變厚導致這樣的關係,也可能是因為聚苯胺遮蔽的關係導致葉綠素分子不易吸收光子而使吸收度降低;FT-IR的結果可以看出許多官能基皆重疊而使判斷上有疑慮;SEM圖可以看出添加葉綠素所聚合出來的高分子藉由交聯劑的添加將葉綠素固定在聚合物當中而使之大部分為球型的形狀。隨著葉綠素濃度的增加由UV-Vis和FT-IR都可看出其包覆量增加,但由SEM跟TEM的結果可以看出其型態不像是完整的球狀。
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.
