微流控技术可控制备异形微颗粒功能材料的研究进展
Recent progress in controllable preparation of anisotropic microparticle functional materials based on microfluidics
摘要
Abstract
Shaped functional microparticles are widely used in industrial and clinical medicine due to their unique characteristics of scattering, rheology and condensation. Compared with other fabrication methods, microfluidics technology has the advantages of precise control, easy adjustment and continuous fabrication process. Moreover, the microscale materials prepared by microfluidics have uniform morphologies and diverse functions. Therefore, the preparation of anisotropic microparticle functional materials by using microfluidics has become a research hotspot. This paper reviews recent progress in fabrication of anisotropic polymer microparticle functional materials by microfluidics. The controllable fabrication of microparticles with polyhedral structures by combining the laminar flow produced in the PDMS microfluidics with controllable lithography, rod-like microparticles by combining the droplet microfluidics with confinement of microchannel or second manipulation, bullet-shaped microparticles by varying the flow rate of continuous fluid and the structure of microchannels, core-shell and multicompartment structure microparticles by surfactant-assisted dewetting of immiscible fluid droplets, helical microparticles by combining the microfluidics with rope coiling effects are highlighted. This review provides guidance for the further design and fabrication of anisotropic microparticle functional materials as well as their applications in industrial applications and clinical pathologies.关键词
