Abstract

The present manuscript examines the dried patterns of sodium chloride (NaCl salt) crystals on the basis of a biopolymer complex fluid drop. The study focuses on the effects of varying relative humidity of the room on the crystal formation and stability. The findings reveal that the morphology of the crystal changes from a cross-crystal pattern to a dendritic pattern with changing humidity, even after initial crystal formation. The same observation was made for drops on a hydrophobic polymer surface. The study provides insight into the morphological changes of NaCl crystals with changing humidity and highlights the importance of considering humidity as a key factor in controlling crystal formation and stability. The findings have the potential to be applied in various fields such as material science, pharmaceuticals, and biomedicine, where controlling crystal formation and stability is essential.
