Abstract

The invention relates to the technical field of high polymer materials, in particular to a liquid crystal polymer film vibrator and a preparation method thereof. The preparation method of the liquid crystal polymer film vibrator comprises the following steps: adding polydopamine nanoparticles into a reaction solution, and then injecting a reaction solution into a liquid crystal box, wherein one surface of the liquid crystal box is in parallel orientation, and the other surface of the liquid crystal box is in vertical orientation; injecting the reaction solution doped with the polydopamine nanoparticles when half of the liquid crystal box is filled, and then carrying out ultraviolet polymerization to obtain a liquid crystal polymer film; and cutting the liquid crystal polymer film to obtainthe liquid crystal polymer film vibrator. The liquid crystal polymer film vibrator disclosed by the invention can vibrate continuously and stably under excitation of fixed focused sunlight, and whensunlight with different focusing degrees is adopted for irradiating, vibration frequency of the vibrator is increased along with increase of the sunlight focusing degree.

Description

technical field

[0001] The invention relates to the technical field of polymer materials, in particular to a liquid crystal polymer film vibrator and a preparation method thereof. Background technique

[0002] The development and effective utilization of solar energy has always been a research hotspot in the field of energy. Solar energy is an inexhaustible, environmentally friendly and green energy. Realizing the transformation of solar energy into mechanical energy, thermal energy and electrical energy has great practical significance for solving current energy problems.

[0003] Photodeformable liquid crystal polymer material is a material that can deform under light, and it can directly convert light energy into mechanical energy of the material. Although many researches are currently devoted to using solar energy to achieve large deformation of liquid crystal polymer materials, the current main research results can only achieve temporary and single deformation of the m...
