| Application | polyethylene glycol diacrylate (PEGDA) as a polyethylene glycol derivative, it is an important biocompatible and degradable environment-friendly polymer material, which can use a certain amount of initiator to initiate polymerization reaction under the condition of heat, light and radiation. PEGDA has been widely used in polymer coatings, flexible devices and biomedical fields. |
| preparation | S1, polyethylene glycol (PEG) was vacuum dried at 50 °c overnight, k2CO3 was triturated and dried overnight at 100 ° C. Under vacuum and cooled in vacuum; S2, 50g PEG was dissolved in mL of anhydrous dichloromethane in a three-necked flask at the added amount shown in Table 2, k2CO3 was added to disperse thoroughly with stirring; S3, acryloyl chloride was dissolved in anhydrous dichloromethane (1:10v/v) according to the addition amount shown in Table 2, and slowly added dropwise to a three-necked flask, the reaction was carried out at room temperature for 24h under the protection of nitrogen; S4, the mixture was filtered to remove solids, the supernatant was distilled at 37 ° C. To remove most of the solvent and then fully precipitated with ether, after washing with diethyl ether for 3-5 times, the product, polyethylene glycol diacrylate (PEGDA), was finally completely dried in vacuo. |
