| titleOfInvention | A kind of purification method of quantum dots |
| abstract | The invention discloses a method for purifying quantum dots, comprising the steps of: providing a quantum dot solution containing long-chain fatty acids and long-chain fatty amines; mixing the quantum dot solution with a branched-chain carboxyl-containing polymer to make The carboxyl group and the long-chain fatty amine are subjected to amidation reaction and purification treatment to obtain a first treatment solution, and the first treatment solution is mixed with a branched-chain hydroxyl-containing polymer, so that the hydroxyl group on the branched chain and the long-chain chain are mixed. The fatty acid is esterified; or, the quantum dot solution is mixed with a branched polymer containing hydroxyl groups, and the hydroxyl groups on the branch are esterified with the long-chain fatty acid, and purified to obtain a second treatment solution , mixing the second treatment solution with a polymer containing a carboxyl group in a branched chain, and performing an amidation reaction between the carboxyl group on the branched chain and the long-chain aliphatic amine; and purifying to obtain quantum dots. The purification method can easily remove long-chain fatty acids and long-chain fatty amines; it is simple, effective, and easy to operate and control. |
