Progress in microfluidics preparation technology of micro/nano cellulose materials

In order to gain in-depth understanding of the research status of micro/nano cellulose materials prepared by microfluidic technology, and to promote its application in various fields, the use of cellulose and nanocellulose as raw materials based on microfluidic technology was reviewed. The latest research progress was reviewed and discussed concentrating on the preparations of cellulose microspheres and microcapsules, nanocellulose microspheres and microcapsules, fiber filaments, films, microtubules, and hydrogels combined with rapid freezing method, in-situ interface complex method and other technologies. Aiming at the challenges in the preparation of micro/nano cellulose materials by microfluidic technology, a corresponding strategy is proposed to tackle material defects, to enhance the ability for micro-channel construction, and to explore technology combination solutions. Development prospects were also scrutinized to provide references for the preparation of micro/nano cellulose materials by microfluidic technology in the fields of material science, tissue engineering and regenerative medicine.
