Microstructures of Poly (9'9-Dihexylfluorene) Grown in the Non-Solvent Vapor

Abstract:

In this research, the microspheres of poly (99-dihexylfluorene) were fabricated with dichloromethane as a good solvent by self-assembly methods. The effects of poor solvent vapor, polymer concentration, and the temperature of environment on the formation of the sphere patterns were investigated. It was found that the microsphere could be easily prepared in the ethanol non-solvent vapor atmosphere. Besides, increasing the environment temperatures was advantageous to fabricate microspheres. Furthermore, the property of non-solvent vapor was a key role to the formation of the sphere.
