Cellulose-based filaments, films and 3d objects and methods of manufacture thereof

Abstract

We provide cellulose-based filaments comprising a negatively charged cellulose derivative bearing anionic functional groups as well as bubble-free films and 3D objects comprising partially decarboxylated carboxymethyl cellulose, wherein these cellulose derivatives have a charge content of less than or equal to about 1.4 mEq/g of cellulose. The filaments have a diameter of between about 1 μm and about 50 μm. Method of producing these filaments and bubble-free films and 3D objects are also provides. These methods comprise extrusion or immersion into a coagulation bath. Films can be overlaid or bent to form 3D objects.
