Evaluation of Modification Functional Groups of Monodisperse Cellulose Nanofiber (CNF)

Introduction

Cellulose is a type of polysaccharide which is the main component of plant cell walls. Cellulose with a fiber diameter of 4 nm to 100 nm, length of several μm, and aspect ratio of 100 or more is called cellulose nanofiber (CNF), and has attracted attention as a leading-edge biomass new material. CNF has a number of outstanding functions. In addition to light weight and high strength, it also has a high gas barrier property, adsorption, and transparency. Moreover, because CNF is a plant-derived material, environmental impacts associated with production and waste disposal are low. Future applications are expected to include automotive components, electronic materials, and packaging. Application News No. A579 introduced an evaluation of the modification functional groups of networked CNFs. This article introduces an example of evaluation of the modification functional groups of monodisperse CNF by using an IRSpirit^TM Fourier transform infrared spectrophotometer.
