Outline of Final Research Achievements

Flake-shaped cellulose particles(FSCPs) and cellulose nanofibers(CNFs) were prepared by mechanical ball milling and wet milling of fibrous cellulose. Biomass-rich and highly-functional rubber-based green composites were prepared by compounding these fillers with natural rubber(NR). Mechanical and functional properties of the composites were evaluated.
The damping and gas barrier properties of NR/FSCP composites were greatly improved by use of epoxidized NR as matrices. The tensile properties of NR/CNF composites were improved remarkably by the addition of chemical treating agents and affected significantly by the length of CNF.
