Cellulose-Based Biomimetics and Their Applications

Abstract

Nature has been producing cellulose since long before man walked the surface of the earth. Millions of years of natural design and testing have resulted in cellulose-based structures that are an inspiration for the production of synthetic materials based on cellulose with properties that can mimic natural designs, functions, and properties. Here, five sections describe cellulose-based materials with characteristics that are inspired by gratings that exist on the petals of the plants, structurally colored materials, helical filaments produced by plants, water-responsive materials in plants, and environmental stimuli-responsive tissues found in insects and plants. The synthetic cellulose-based materials described herein are in the form of fibers and films. Fascinating multifunctional materials are prepared from cellulose-based liquid crystals and from composite cellulosic materials that combine functionality with structural performance. Future and recent applications are outlined.

Cellulose and cellulose-based materials with properties that mimic natural designs and functions inspired by gratings, helical filaments, structurally colored water, and stimuli-responsive materials that exist in insects and plants are reviewed. The synthetic cellulose-based materials described are in the form of fibers and films. Future and recent applications are outlined.
