Atmospheric Cold Plasma Assisted Preparation of Cellulose-based Janus Membrane for Biomedical Application

Cellulose-based Janus membrane with asymmetric wettability has broad applications in the fields of human sweat excretion, drug release, and hemostasis [1–3]. However, due to the significant difference in wettability between the two sides of Janus membrane, the fabrication process is relatively complicated and costly [4].
