General description

Polyethylene glycol (PEG) is a synthetic, hydrophilic, biocompatible polymer that has a wide range of uses in PEGylation, surface conjugation, nanoparticle coating, and crosslinking for hydrogels. PEGs are made by polymerizing ethylene oxide via a ring-opening reaction to produce a wide range of molecular weights and molecular weight distributions (polydispersity).

Application

Polyethylene glycol 10000 can be used as a surfactant in the synthesis of Ni12P5 hollow microspheres via the hydrothermal method in the presence of hexamethylenetetramine (HMT). PEG 10000 significantly improves the formation of high-quality hollow microspheres, without this surfactant morphology is near-spherical particles.[1]
It can also be used as:
  • A reactant to synthesize N-PEGylated-thiazolium salt, which is used as an organocatalyst for the benzoin condensation.[2]
  • A nonionic dispersive agent in the preparation Nd2Si2O7 ceramic pigment by a co-precipitation method.[3]
