초록

본 연구에서는 에폭시/폴리썰폰 복합체를 경화온도와 조성비를 변화하며 제조하여 시간에 따른 상분리 과정, 모폴로지, 전환율, 그리고 T_g의 변화를 관찰하였다. 경화온도의 범위는 180-240℃까지 변화하였으며, 에폭시/폴리썰폰의 조성변화는 80/20-40/60의 범위에서 관찰하였다. 제조된 시료는 경화반응 전에는 전 조성에서 균일하고 투명하지만, 경화가 진행됨에 따라 에폭시의 분자량이 증가하여 상분리가 일어났다. 에폭시/폴리썰폰의 조성이 같은 경우에는 경화반응속도가 증가할수록 분리된 상의 크기가 증가하였고, 같은 경화온도에서는 에폭시의 함량이 증가할수록 분리된 상의 크기가 증가하였다. 위에 언급한 경화온도와 조성변화의 범위에서 조성변화가 분리된 상의 크기에 더 큰 변화를 주었다. 모든 경우 폴리썰폰이 매트릭스를 구성하였으며, 광산란 결과와 현미경에 의한 모폴로지 결과는 잘 일치하였다. 또한 에폭시 전환율과 T_g변화, 그리고 폴리썰폰의 분자량 변화에 관한 효과도 관찰하였다.

A series of high performance epoxy/polysulfone blends were prepared with varying curing temperature and composition. The phase separation process, morphology, conversion of epoxy, and T_g were observed for the sample prepared. The curing temperature range was 180-240℃ and she composition of epoxy/polysulfone was varied within 80/20-40/60. Before the curing reaction, the solution casting sample was homogeneous and transparent in all composition range. And the phase separation was occurred due to the molecular weight increase during curing reaction. At fixed epoxy/polysulfone composition, the size of phase separated domains increased with increasing curing temperature. And at fixed curing temperature, the size of domains increased with increasing epoxy composition. The composition variation was more effective to controlling the size of phase separated domains than the change of curing temperature within which was mentioned above. Polysulfone was a continuous matrix in all composition range. The scattering data agrees well with the morphology results by optical microscope and SEM. The relation of epoxy conversion and T_g, the effect of molecular weight of polysulfone were also observed.
