Nanocellulose fibers bioengineered by bacteria are a high-performance three-dimensional cross-linked network which can confine a dispersed liquid medium such as water. The strong chemical and physical interactions of dispersed water molecules with the entangled cellulosic network allow these materials to be ideal substrates for effective liquid separation. This type of phenomenon can be characterized as green with no equivalent precedent; its performance and sustainability relative to other cellulose-based or synthetic membranes are shown herein to be superior. In this work, we demonstrated that the renewable bacterial nanocellulosic membrane can be used as a stable liquid-infused system for the development of soft surfaces with superwettability and special adhesion properties and thus address intractable issues normally encountered by solid surfaces.

细菌超疏油性纤维基质:自然发生的液体注入系统,用于油水分离

由细菌生物工程化的纳米纤维素纤维是一种高性能的三维交联网络,可以限制诸如水之类的分散液体介质。分散的水分子与纠缠的纤维素网络之间的强烈化学和物理相互作用使这些材料成为有效液体分离的理想基质。这种现象可被描述为绿色,没有同等的先例。相对于其他基于纤维素的膜或合成膜,其性能和可持续性在本文中显示是优越的。在这项工作中,
