Muroi, Riku published the artcileSelf-healing thiol-ene networks based on cyclodextrin-adamantane host-guest interactions, COA of Formula: C17H28O8S4, the main research area is thiol ene cyclodextrin adamantane host guest interaction.
The reactions of β-cyclodextrin, pentaerythritol propoxylate and 1-adamantanecarboxylic acid with allyl bromide in the presence of basic salts generated their allylated products (ACD, APEP and AAd, resp.). The thiol-ene photopolymerizations of these allylated compounds and pentaerythritol tetrakis(3-mercaptopropionate) (S4P) produced thiol-ene network films (ACD-S4P, ACD-APEP-S4P, ACD-AAd-S4P, APEP-AAd-S4P and ACD-APEP-AAd-S4P). The FT-IR and gel fraction measurements of the photo-cured films revealed that almost all the thiol and allyl groups were consumed, and polymer networks were certainly formed. Glass transition temperatures (0.5 and 0.3 °C) of ACD-S4P and ACD-AAd-S4P were higher than those (-9 to -15 °C) of other films incorporating APEP. The tensile strength and modulus of ACD-S4P were much higher than those of the films incorporating APEP or AAd. Only the films incorporating both ACD and AAd possessed the self-healing property. ACD-AAd-S4P showed a higher tensile strength and modulus than ACD-APEP-AAd-S4P did. ACD-AAd-S4P was healed twice at 80 °C and only once at room temperature ACD-APEP-AAd-S4P was healed only once at 80 °C. The maximum healing efficiency was 85% for tensile modulus of ACD-AAd-S4P.
