Panoramica

Polyethylene glycol (PEG) is a biocompatible, inert synthetic polymer with repeating ether oxygen (-CH2-CH2-O-) units. It can be synthesized via anionic polymerization of ethylene oxide. Due to its non-immunogenicity and high water solubility, it is widely used in biological and medical applications.

Application：

PEG can be used to functionalize magnetite nanoparticles. PEG-coating magnetic cores provides good stability while preserving the magnetism of the nanoparticles.

It can be used for the surface modification of photocatalytic titanium dioxide nanoparticles for self-cleaning coatings. PEG-coated TiO2 nanoparticles can be prepared under mild conditions and exhibit excellent colloidal stability.

It can be used as a crosslinking agent to prepare thermosensitive injectable hydrogels based on poly(N-isopropylacrylamide). Adding PEG improves the chemical and mechanical properties of the hydrogel and prevents its dissolution in swelling media. Due to their biocompatibility and biodegradability, these hydrogels are widely used in biomedical applications.
