| titleOfInvention | Preparation method of triblock nonionic polyurethane fluorine-containing short-chain surfactant |
| abstract | The invention discloses a triblock nonionic polyurethane fluorine-containing short-chain surfactant and a preparation method thereof. The triblock nonionic fluorine-containing short-chain surfactant is obtained by reacting polyethylene glycol with diisocyanate according to a certain proportion under the catalysis of organic bismuth to obtain a prepolymer with two ends being isocyanate groups, and then carrying out coupling reaction on the prepolymer and short-chain fluoroalcohol. The triblock nonionic fluorine-containing short-chain surfactant has the characteristics of excellent self-assembly performance and high surface activity in an aqueous solution, simple preparation method, easily obtained starting materials which are general reagents, no organic solvent in the synthesis process, good biocompatibility and biodegradability due to the short fluorocarbon chain and polyurethane structure, application to drug transportation, simulation of biological membranes and the like, and wide application prospect. |
