DEVELOPMENT OF LIGHTWEIGHT FOAMED PLASTICS WITH HIGH MECHANICAL PROPERTIES BY USING HYDROPHOBIC MODIFIED CELLULOSE NANOFIBER AND CONTROLLING CELL MORPHOLOGIES

摘要

1) The addition of CNF decreased the bubble size of PA6 foams while keeping moldability. 2) The Acetylated CNF10%/PA6 foams exhibited 1.8 times the specific modulus of PA6 in a relative density of 0.7. 3) The addition of CNF to PA6 type thermoplastic elastomer was found to be effective in reducing cell size and increasing compressive stress while maintaining flexibility.
