AI Technical Summary

Technical Problem

Existing technologies struggle to achieve precise control and directional reconstruction of the morphology of non-spherical micro/nanoparticles in pure liquid systems without chemical templates, and the resulting products exhibit low surface purity.

Method used

A synergistic control method combining laser irradiation and ultrasonic fields was employed to prepare a colloidal suspension of micro- and nano-particles through the coupling effect of pulsed laser and ultrasonic fields. By utilizing the spatial pressure difference and acoustic radiation force of the ultrasonic field in conjunction with laser thermal energy, multi-field synergistic control of micro- and nano-particles was achieved, breaking the natural spherical tendency of molten particles and realizing the directional reconstruction of non-spherical particles.

Benefits of technology

This technology enables precise control of the non-spherical morphology of micro and nanoparticles in a purely physical system. The resulting products have high surface purity and are applicable to a variety of materials, thus broadening their application prospects in precision optical detection, sensors, and biomedical fields.

Abstract

The application discloses a method for laser irradiation and ultrasonic field synergic regulation of micro-nanoparticle diversified morphology, and relates to the technical field of micro-nano material processing and manufacturing. The method comprises the following steps: grinding target micro-nanoparticles, ultrasonic dispersion in a solvent to prepare a micro-nanoparticle colloidal suspension; placing the micro-nanoparticle colloidal suspension in an ultrasonic field, and simultaneously performing pulsed laser irradiation to prepare a micro-nanoparticle colloidal solution with directional reconfiguration of morphology; then, centrifugation, washing and drying are performed to prepare micro-nanoparticles with target morphology or assembled configuration. The method effectively breaks the physical limitation of spontaneous formation of spherical structure of micro-nanoparticles in a liquid phase environment due to the interface energy minimization effect, not only realizes accurate regulation of non-spherical monomer morphology such as rod-shaped and fusiform-shaped, but also simultaneously realizes directional assembly and welding of complex configurations such as chain-shaped and skeleton-shaped between micro-nanoparticles. The application solves the problem of lack of physical regulation of non-spherical micro-nanoparticle morphology in the prior art.
