Abstract

The invention relates to a preparing method for micro-nano organic ferroelectric particles. The method includes the following steps: adding second solvents (water, acetone and ethanol) of appropriate amount in a methyl ethyl ketone solution of a ferroelectric polymer, and uniformly mixing; coating the surface of a clean substrate with the mixed solution; obtaining the micro-nano ferroelectric polymer particles after the solvents are evaporated. Through adjusting the mass concentration of the ferroelectric polymer solution and selecting the second solvents, the ferroelectric particles with different particle diameters can be obtained; according to the invention, the preparing technology is simple, the micro-nano ferroelectric polymer particles can be prepared through mixing the two kinds of solvents, and the particle diameter of the micro-nano ferroelectric polymer particles can be adjusted and controlled through adjusting the volume ratio of the two kinds of solvents and the mass concentration of the ferroelectric polymer particles.

Description

technical field

[0001] The invention relates to a method for preparing micro-nano-sized organic ferroelectric particles. Add an appropriate amount of the second solvent (water, acetone, ethanol) to the methyl ethyl ketone solution of the ferroelectric polymer and mix it evenly. The mixed solution is coated on the surface of the clean substrate. After the solvent evaporates, the micro-nano-sized iron can be obtained. Electropolymer particles. Background technique

[0002] Ferroelectric polymers have pyroelectric, piezoelectric and ferroelectric properties, and can be used to prepare micro-nano-scale infrared detectors, piezoelectric drivers, sensors, etc. However, since ferroelectric polymer materials are easily corroded by organic solvents such as acetone, it is generally difficult to realize the processing and preparation of micro-nanoscale ferroelectric polymer structures by photolithography in the microelectronics industry. Finding a simple and feasible preparation meth...
