Beschreibung

Allgemeine Beschreibung

Neopentyl glycol diglycidyl ether (NGDE) is a low-toxic epoxy molecule with two epoxy pendant groups at the end of the long chain. It has excellent reactivity, low viscosity, and cross-linking properties. It facilitates the resin with high strength and impact resistance. It is used as a precursor to synthesize hydrogels for drug delivery, dental materials, coating, and adhesives for medical devices and tissue engineering. It is also used as a solid matrix to fabricate light-emitting devices like OLEDs.

Anwendung

Neopentyl glycol diglycidyl ether can be used,

• As a cross-linking agent to prepare Pullulan/polydopamine hydrogels for selective adsorption of pollutant cationic dyes.
• As a monomer to synthesize gel polymer electrolytes for Li-ion batteries via cationic ring-open polymerization.
• As a precursor for the synthesis of hybrid epoxy methacrylate resins cationic and free-radical photopolymerization. These epoxy resins can be used as anti-corrosion and decorative coatings.
• To synthesize epoxy nanocomposites for fabrication of light-emitting devices.
