Among these results, we suggested that the monomer structure play a important role between E-O performances and morphology. Monomer STD02 shows fastest response time, and monomer M3 exhibits slowest one. As a result for roughness, it's the same with response time. From SEM photograph, the beadlike morphology was obtained from monomers without spacers. On the other hand, the filberlike morphology was obtained from monomers with spacers. It's suggested that the more harder structure will lead to the former, and the more softer structure will lead to the latter.
发现 STD02 反应时间最快,而 M3 则是最慢,而粗糙度大小也是与反应时间相符合,最大的是 STD02 而最小的是 M3,在 SEM 下结果显示,各单体所呈现的型态皆为颗粒状且排列均匀,因无含烷链段关系导致形成的型态为颗粒状,论文里有提到另一种单体含烷链段其所形成的型态为纤维状,以结构上来看,越是刚硬之单体所形成的型态都较易为水滴或是米粒状,而结构上越是柔软,所形成的型态都较易为稻穗或是纤维状。
