Nanocellulose (NC) Technology

 

Nanocellulose is a non-toxic, biodegradable cellulosic nanomaterial.  It has several noble properties including lightweight, mechanical strength, liquid crystalline phases, and biocompatibility.  Thus, nanocellulose has many potential applications in automotive, aerospace, food packagining, 3-D printing resins, and others.  However, current technologies of nanocellulose including cellulose nanocrystals (CNC) and cellulose nanofibrils (CNF) have several drawbacks:  high production cost, caustic and toxic processes, and poor adhesion to polymeric materials.

 

Innotech Materials has recently developed energy and cost-effective catalytic processes to produce oxidized nanocellulose derivatives through cellulose oxidation and cleavage.  The hygroscopic nanocellulose has been further processed to enhance adhesion to hydrophobic polymer such as polypropylene through esterification or amidation.  The process is environmentally friendly and produces inexpensive nanocellulose. 

 

Oxidzied cellulose and nanocellulose

 

Catalytic oxidation and cleavage of cellulose have been developed to produce  oxidized cellulose and nanocellulose with 87% and 90% crystallinity, respectively. These are ~15% solid content white hydrogels and insoluble to water and organic solvents. The SEM images shown above are in 500 micron scale for hardwood bleached pulp and oxidized cellulose and in 500 nm scale for oxidized nanocellulose.  Oxidized nanocellulose has been further processed to produce modified nanocelluloses incorporating carboxylic acids, amines, and amino acids.
