Cotton fiber dissolution and regeneration and 3D printing of cellulose based conductive composites

A method for making a 3D printing cotton cellulose-based conductive composite, comprising:

• obtaining a core matrix comprising cotton cellulose fibers or cotton microcrystalline cellulose, wherein the cotton cellulose fibers comprise 1-20% of bleached cotton cellulose fiber with a Degree of Polymerization (DP) over 5,000, or the microcrystalline cellulose comprises 5-50% microcrystalline cellulose with a DP of 200-250;
• dissolving the cotton cellulose fibers or cotton microcrystalline cellulose in a solvent;
• adding a 3D printing process enhancer to stabilize the cotton cellulose fibers or cotton microcrystalline cellulose disrupted during a printing process;
• printing, layering or depositing the dissolved cotton cellulose fibers or cotton microcrystalline cellulose and a conductive material;
• and
• stabilizing the printed cotton cellulose fibers or cotton microcrystalline cellulose to form the 3D printing cotton cellulose-based conductive composite.
