Observing the CNF in the ink solid content of cellulose nanofiber ballpoint pens!
We would like to introduce our observation of cellulose nanofibers (CNF) using transmission electron microscopy (TEM). Utilizing the know-how we have developed in observing resin materials with TEM, we examined the CNF in the ink solids of commercially available cellulose nanofiber ballpoint pens. We observed CNF with a width of approximately 10 nm that appeared to be entangled with ink pigments, and it was found that the ink contains CNF with varying degrees of fibrillation. [Observation Results] - CNF with a width of approximately 10 nm that appeared to be entangled with ink pigments was observed. - Submicron-width CNF was also observed. - Several thin microfibrils, around a few nanometers in diameter, bundle together to form fibers approximately 100 nm thick. - The ink contains CNF with varying degrees of fibrillation. *For more details, please refer to the related links or feel free to contact us.
