Add-Ons
TEGDMA (Triethylene glycol dimethacrylate) (C14H22O6) is a bifunctional aliphatic methacrylate monomer featuring two reactive methacrylate groups bridged by a flexible, short oligo(ethylene glycol) ether spacer (-(CH2CH2O)3-). In advanced energy storage research, TEGDMA is utilized as an exceptional crosslinking agent for Gel Polymer Electrolytes (GPEs) and in situ polymerized solid/gel battery systems, providing a favorable balance between mechanical network stability and enhanced alkali metal ion solvation.
Its main features are: (1) Bifunctional Methacrylate Architecture: Features two terminal methacrylate (CH2=C(CH3)COO-) groups (f = 2) that undergo controlled free-radical polymerization to form a stable 3D polymer network. (2) PEO-Like Oligo-Ether Backbone: Unlike purely aliphatic hydrocarbon spacers (such as HDDA or HDDMA), TEGDMA contains recurring ether-oxygen atoms (-C-O-C-) that structurally mimic polyethylene oxide (PEO). This local chemical environment actively assists in ion coordination and salt dissociation. (3) Low Liquid Viscosity & Miscibility: Possesses moderate room-temperature viscosity and dissolves readily in aprotic carbonate binary/ternary solvent blends (EC/DEC/DMC/PC) and liquid monomer mixtures, ensuring thorough infiltration of porous separator membranes and electrode pores prior to curing. (4) Optimized Chain Flexibility: The flexible triethylene glycol chain provides higher conformational mobility than shorter dimethacrylates (like EGDMA), lowering the glass transition temperature (Tg) and preventing excessive network brittleness during cycling.
