AI Technical Summary
In the preparation process of existing PVDF piezoelectric materials, it is difficult to increase the β-phase crystal content, and the post-processing process damages the function of the composite material, making it impossible to achieve thermal and electrical stimulation regulation in specific regions.
By mixing photothermal conversion materials with PVDF-based polymers and then performing laser irradiation and polarization treatment, regional crystallization is formed, achieving controllable regional distribution of surface potential and photothermal effect.
The crystallization content and ferroelectric properties of the PVDF piezoelectric phase were improved, enabling controllable thermal and electrical stimulation in specific regions, which is suitable for precise regulation of cell behavior in the biomedical field.
