碩士 === 中原大學 === 化學工程研究所 === 100 === This work reports the synthesis of host-guest inclusion-complex using Ferrocene carboxylic acid (Fc-COOH) and -cyclodextrin (beta-CD). The guest polymer, poly(glycidyl methacrylate)-ferrocene (PGMA-Fc), was synthesized from reaction of epoxy group of PGMA and Fc-COOH, and the host molecule beta-CD-HDI-beta-CD contains two beta-CD groups. After the crosslinking reaction between the host and guest, the polymer is coated on copper foil or silica wafer. The electrochemical property of Fc-COOH allows desorption of the inclusion body by electrification, forming a reversible crosslink system, which can be applied in self-healing materials. The guest polymer grafted poly(tetrafluoroethylene) (PTFE), is also synthesized. After hydrogen plasma treatment on e-PTFE membrane, PGMA was grafted onto membrane through surface-initiated atom transfer radical polymerization (ATRP). Fc-COOH is then grafted through the ring-opening reaction of the e-PTFE-g-PGMA, forming a guest membrane, e-PTFE-g-PGMA-Fc. The membrane is then soaked into host aqueous solution to obtain the host-guest membrane, e-PTFE-g-PGMA-Fc/beta-CD-HDI-beta-CD. The structure and morphology of membrane surface after electrification induced desorption of inclusion body are investigated. This membrane is also applied in the study of protein desorption.
