Synthesis of Tannic Acid-based Epoxy Resins for Improvement of Flame Retardancy |
| 초록 |
Epoxy resin, one of thermosetting polymers, has been applicable to various fields such as coatings, adhesives, and advanced composites. Recently, environmental issues being on the rise, researches for synthesizing epoxy resins using bioresources as precursors have been conducted. Among bioresources, tannic acid (TA) is a polyphenolic compound containing digalloyl ester groups conjugated to a glucose core, which would be a multifunctional epoxy hardener. In this study, TA as a hardener is reacted with the epoxy ring of commercially-available diglycidyl ether of bisphenol A (DGEBA). Optimal condition of the reaction is empirically demonstrated through dynamic scanning calorimetry (DSC) and Brillouin spectra. Mechanical and flame-retardant properties of TA-based thermosets are evaluated. The result is related to the distinct characteristic of TA such as existence of multiple hydrogen bonding sites in the molecular structure, charring effect, and radical quenching. |
