Add-Ons
THFA (Tetrahydrofurfuryl Acrylate, >99.0%) (C8H12O3) is a specialized monofunctional acrylate monomer featuring a five-membered saturated cyclic ether (tetrahydrofuran ring) attached via a flexible methylene linkage to a reactive acrylate group. While multi-functional crosslinkers provide primary 3D network connectivity, THFA is utilized in advanced energy storage research as a high-polarity functional co-monomer and reactive diluent for Gel Polymer Electrolytes (GPEs) and solid-state polymer electrolyte systems. It combines low liquid viscosity with cyclic ether oxygen sites that actively assist in alkali metal ion solvation.
Its main features are: (1)Tetrahydrofurfuryl Ring Architecture: Features a cyclic ether moiety that provides localized oxygen lone pairs, creating a favorable local environment for Lewis acid-base interactions with lithium (Li+) or sodium (Na+) ions. (2) Low Liquid Viscosity & Reactive Dilution: Possesses very low room-temperature viscosity, enabling it to function as an efficient reactive diluent that dissolves readily in aprotic carbonate binary/ternary solvent blends (EC/DEC/DMC/PC) and thoroughly wets porous separator membranes (glass fiber, PE/PP, or Celgard) and dense electrode pores prior to curing. (3) Rapid Acrylate Polymerization Kinetics: As an acrylate derivative, THFA exhibits fast free-radical propagation rates under thermal or UV activation, ensuring efficient copolymerization into the growing polymer network.High Polar Miscibility: The polar cyclic ether structure prevents phase separation during in situ gelation, maintaining homogeneous distribution throughout the polymer-solvent-salt matrix.
