Summary

The fundamental technology to improve the heat resistance of lignocellulose nanofibers and dispersibility of lignocellulose nanofibers in the matrix resins such as Polyamide 6 (PA6), polyacetal (POM), polylactic acid (PLA), polyethylene (PE), and polypropylene (PP) has been developed in order to use cellulose nanofibers to reinforce automotive and housing plastic parts.
The project consists of four parts as follows: 1) development of the technology for the isolation of ligno pulps/cellulose nanofibers from plant resources such as wood; 2) development of the technology for the chemical modification of lignocellulose nanofibers suitable for plastic reinforcement; 3) development of the continual production process of lignocellulose nanofibers reinforced composites; 4) development of the technology for the evaluation of cellulose nanofibers (CNF) size distribution and surface chemical reactivity. In parallel, lignocellulose nanofibers reinforced plastic compounds were prepared to supply to automotive companies as well as housing company, who joined in this project as advisers and supplied their evaluations. The results were as follows.

1. The technology for the isolation of ligno pulps/CNF from wood and rice straw was studied and the improvement of heat resistance was attained.
2. The chemical modification of ligno CNF suitable for thermoplastic reinforcement was studied. The reinforcement using chemically modified 10wt% cellulose nanofibers was found to increase Young’s modulus and bending strength of PA6, PLA, POM, HDPE and PP by 1.5-2.5 times.
3. The continual production process of ligno CNF reinforced plastics was developed and the test plant (producing capacity: 1 ton/year based on 10% CNF content) starting from wood was constructed at RISH, Kyoto University.
4. The development of the production process of ligno CNF reinforced composites with high lignin and hemicellulose content was studied. A combination of structural control of lignin and chemical modification of hemicellulose resulted in high Young’s modulus and low thermal expansion material by compression molding.
5. The micro-foaming of chemically treated CNF reinforced PA6 was tried using super critical N2 method.
