| 摘要 |
The present invention comprises: a step for heat-treating one or more biomasses selected from bamboo, Ravenna grass, oil palm, and straw, with superheated steam, to obtain biomass fibers; a step for using a multi-screw extruder to blend an aqueous polyvinyl alcohol solution, maleic anhydride-modified polypropylene, or low-molecular-weight polycaprolactone into the biomass fibers, and extruding the result while kneading the same to obtain biomass nanofibers; and a step for blending a polymer resin into the biomass nanofibers and extrusion-molding the result with the multi-screw extruder, thereby obtaining a polymer resin complex containing biomass nanofibers. |
