Device and method for estimating the molecular chain aggregation

High accuracy estimation based on the electromagnetic wave propagation property

Overview

　Materials containing nanocellulose are known to have higher strength than the base material. However, the nanocellulose properties vary depending on the degree of its aggregation. The light scattering is known as a method to estimate the aggregation. However, when the scattered light from the molecular chain is weak, as in the case of materials containing nanocellulose, it is not possible to estimate the aggregation with high accuracy from this method.　
　This invention is able to provide a device and method that estimates the aggregation with high accuracy, and its material manufacturing method. This invention can estimate the aggregation for not only nanocellulose but also multiple molecular chains with structures containing water molecules. This invention is based on the feature that there is a strong correlation between the aggregation and the electromagnetic wave propagation property in order to have high accuracy estimation.
