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.
  • Micro-nanostructured PEG-DA (PEG-diacrylates) hydrogels for biomedical applications.

It can also be used as:
  • A template to prepare micro/mesoporous structure of silica by sol-gel process.
  • A stabilizing agent in the synthesis of metal nanoparticles.
