Carbon Nanotube Pastes and Inks

Opportunity

Carbon nanotube (CNT) pastes and inks offer the promise of a vast range of beneficial properties in products for consumer electronics and many other applications.

Even as the cost of CNTs is decreasing as manufacturers ratchet up production, CNTs show numerous handling problems that prevent their full benefits from being realized.

 

Challenge

Fundamental issues currently prevent mass production of optimal CNT composite formulations and products:

• Poor dispersion and uneven distribution
• Restricted filler concentration/loading
• Adverse rheology and difficulty in processing
• Inadequate properties and performance
• Inadequate material shelf life due to instability

 

The NanoQuan Solution

Our breakthrough mixing-and-dispersion technology solves the problems of unwanted CNT agglomeration. It solves the problems of poor loading control and non-uniform dispersion and distribution of CNTs in a vast range of host matrix materials.

 

CNT Formulators And Product Developers Can Now Achieve:

 Uniform dispersion and distribution
• Greatly improved rheology
• Unsurpassed CNT concentration levels
• 
Greater stability for extended shelf life
