설명

애플리케이션

Polyethylene glycol 35000 (PEG 35000) is a hydrophilic polyether compound that can be used to synthesize:

• Hierarchically structured silica monoliths for the fabrication of micro-bioreactors.[1]
• Micro-nanostructured PEG-DA (PEG-diacrylates) hydrogels for biomedical applications.[2]

It can also be used as:

• A template to prepare micro/mesoporous structure of silica by sol-gel process.[3]
• A stabilizing agent in the synthesis of metal nanoparticles.[4]
