A Self-Healable Elastic Coating Material With Excellent Optical Properties and Surface Hardness for Flexible Displays |
| 초록 |
A self-healable elastic coating material with excellent optical properties and surface hardness is prepared and the optical and mechanical properties are examined in this study. A dihydroxy fluorinated imide moiety (DHFI) is synthesized by thermal imidization between 4,4'-(hexafluoroisopropylidene)diphthalic anhydride and 2-aminoethanol. A mixture of DHFI and a polyol is reacted with a cross-linker containing multiple isocyanate groups to form a self-healable elastic coating material (ShEC), whereas a polyol is reacted with a crosslinker to obtain a conventional elastic coating material (CEC). In comparison to CEC, ShEC exhibits significantly enhanced surface hardness and self-healing properties. These properties are ascribed to the unique supramolecular structure resulting from the strong hydrogen bonding between the imide groups in DHFI and urethane groups in the matrix. |
