本實驗主要可分為兩個部分,第一部分為苯胺四聚體/聚胺酯之共聚物合成,利用氯化鐵作為二苯胺的氧化劑,藉由氧化還原的方式合成出苯胺四聚體,再以預聚合法的方式,以醚型聚氧四亞甲基二醇(PTMO)分子量2900作為軟鏈段,二苯甲基二異氰酸鹽(MDI)作為硬鏈段,反應生成有-NCO官能基的PU預聚物,在其頭尾接上帶有-NH2官能基之苯胺四聚體,最後形成具有尿素基之共聚物(Copolymer)。
第二部分為磁流變彈性體之製備,將苯胺四聚體/聚胺酯之共聚物作為磁流變彈性體的基體,以溶劑DMF溶解後加入酸摻雜劑,使苯胺四聚體形態轉變為鹽式半氧化還原態(Emeraldine salt),具有導電性質,再加入磁性粒子羰基鐵粒子(Carbonyl iron)在磁場下使鐵粒子產生排列,固化後形成具導電性磁流變彈性複合材料。
儀器量測使用FTIR、質譜儀作為共聚物之結構鑑定,使用SEM來看複合材料的剖面形態,再藉由TGA、DMA、SQUID、四點探針等儀器來探討複合材料之物性,最後使用雙平版流變儀測試其磁流變效應。


This study is divided into two parts. In the first part, the study is based on tetraaniline synthesized by using dianline as monomer and FeCl3 as an oxidant. The prepolymer was reacted with the soft segment of ether-type poly(tetramethyleneglycol), and hard segments of 4,4-diphenylmethane diisocyanate. Then the tetraaniline could connected end to end in two short of the prepolymer to form copolymers.
In the second part of the study, MREs are prepared so that the copolymers of tetraaniline/ polyurethane belong to the MRE matrix. Then, after dissolving the DMF, Acid dopant was added so that tetraaniline formation transforms to emeraldine salt (which has conductive properties). Next, the magnetic carbonyl iron was added, forming a magnetic field to ensure that iron particles were arranged in rows. Upon solidification, a conductive of MRE composite material is synthesized.
The structures of copolymer were investigated by FTIR spectra and MS. The analysis of microstructure was by SEM, while physical properties of composites were investigated by TGA, DMA, SQUID, and the Four-point probe. Finally, the rheometer test was used to study the Magnetorheological effect.
