Highlights
Many industrial products involve drying of suspensions of small particles
We study the samples of colloidal particle suspension with and without cellulose nanofibers (CNFs)
Suspended particles of sample A aggregated on the periphery of the droplet and clear scarcity can be recognized inside the circular domain (Figure 2(a))
Summary
Pigment inks are typical examples, where particles with specified colors are dispersed in liquid. The drying of the dispersant liquid of the inks discharged from the nozzles of inkjet printers leaves thin films of accumulated particles on a solid surface, such as paper. One of the related intensive research areas is the fabrication of colloidal photonic crystal, which is the assembled structure of colloidal particles typically in regular lattice patterns. They may find applications in pH sensors [5] and laser sources with variable wavelength [6]. Drying of particle dispersion is widely exploited in scientific research and industry
