Abstract
The present disclosure relates to a polymer complex containing microcellulose fibers comprising nanofibrils and fine particles; and a polymer matrix comprising a polyester resin. According to the present disclosure, there is provided a polymer complex capable of exhibiting excellent mechanical properties while being environmentally friendly by including cellulose fibers as a reinforcing material.
Claims15
A polymer complex comprising microcellulose fibers;
- and a polymer matrix,
- wherein the microcellulose fibers comprise nanofibrils and fine particles, and the microcellulose fibers are fibrillated by growth of the fine particles on the microcellulose fibers,
- wherein the polymer matrix comprises a polyester resin,
- wherein the nanofibrils are bonded to a surface of the microcellulose fibers, and the fine particles are bonded to the nanofibrils or bonded to the surface or inside of the microcellulose fibers, and
- wherein the fine particles are particles with a minor axis diameter of 0.01 μm to 10 μm.
