technical specification
CNF vs CNC technology
Having a fibre form with an aspect ratio of 1/100 or greater
Manufacturing process: Mechanical methods are used so that the fibres can be kept in their original state.
Characteristics: Maintains intact fibre structure with excellent reinforcing effect.
Has a crystal form with an aspect ratio of 1/50 or less
Manufacturing process: Manufactured by acid hydrolysis reaction (treatment with sulphuric acid, etc.)
Characteristics: High purity in the crystalline state region with unique optical properties
The reason for the difference in morphology between CNF and CNC is the manufacturing method. Since CNF is manufactured mechanically, the fibres are able to remain in their original form as a whole; whereas CNC is manufactured by acid hydrolysis reaction, and its crystal form is such that the amorphous regions are dissolved by strong acids, leaving only the crystalline regions. Although different scholars have different criteria for distinguishing between CNF and CNC, they are generally distinguished by shape and aspect ratio (diameter/length).
