| Summary: | 碩士 === 中原大學 === 化學研究所 === 100 === In this dissertation, three major topics have been thoroughly discussed. First topic is focused on the preparation of biomimetic room-temperature cured epoxy resin coating and study their potential application in corrosion protection. It should be noted that the coating with biomimetic structures was found to reveal effective corrosion protection performance as compared to that of coating without biomimetic structures based on a series of electrochemical Secondly, amine-capped aniline trimer (ACAT) was incorporated into the commercially polyurethane (PU) foam through chemical foaming process, leading the formation of reversibly dopable/de-dopable electroactive PU (EPU) foam. It should be noted that the incorporation of ACAT may effectively enhance the mechanical strength of neat PU foam based on the tests in tensile and compression mode. Moreover, the reversibly HCl-dopable properties were also found in as-prepared EPU foam. Upon HCl doping, the color of EPU was found to change from blue to green, which was similar to that of polyaniline. The third topic focused on the PU foam containing graphene sheets. First of all, graphite was modified through Friedel-Crafts acylation reaction to give graphene surface with amine functional groups, followed by introducing to the forming process of polyurethane foam reaction, to give formation of PU/graphene composite foam. Upon addition of graphene sheets, with the increase of graphene content, SEM can decrease the pore diameter of composite foams. it indicated that the crosslinking density of composite foams is increasing. Finally, upon addition of graphene sheets into composite foams, the mechanical strength in tensile- and compression- mode of composite foams indicated that the addition of graphene may effectively enhance the mechanical strength ~ 4 times.
