Assignee: WINBOND ELECTRONICS CORP.
Field: Macromolecular chemistry, polymers (Chemistry)
Classification: CPC C  B | IPC B  C

Claim 0:
1. A method of manufacturing a composite material, comprising:
providing a nanocellulose core;
modifying the nanocellulose core;
forming metal ions of metal seed generation points on a surface of the modified nanocellulose core;
performing a first reduction reaction to reduce the metal ions of the metal seed generation points to form metal seeds; and
performing a second reduction reaction to reduce the metal ions of the metal seed generation points at the metal seeds to form a metal shell covering the surface of the modified nanocellulose core,
wherein the step of modifying the nanocellulose core comprises performing a substitution reaction on hydroxyl groups on carbons of the nanocellulose core with a metal M to form a metal-substituted hydroxyl group —OM.
