This study investigates the crystallization and self-assembly phenomena of polyacrylamide (PAM) solutions during evaporation. While traditional thin-film fabrication methods such as spin coating drop casting are commonly used, this utilizes a simple evaporation approach to gain insights into processes PAM solutions. We examined with varying concentrations (1%, 2%, 5%) observed resulting crystalline structures morphological changes Spectroscopic absorbance measurements were employed analyze concentration gradients patterns. The findings reveal that gradient significantly impacts behavior 2% solution exhibited clearest most regular patterns, whereas 1% 5% displayed more complex irregular morphologies. These observations provide new how influences crystallization, contributing better understanding polymer self-assembly. novelty lies in exploring through controlled evaporation, offering valuable for development films.
