Extensive research has been conducted on template-based method, particularly those using cylindrical channels (e.g., anodized aluminum oxide (AAO) template) to create nanorods since their first introduction in the 1990s. While this approach offers many advantages, it also presents significant practical challenges. One major issue is the tendency of nanorods to aggregate, which negates their individual properties. To preserve these unique properties, nanorods must remain stably dispersed in solution. In a previous study (J. Korean Phys. Soc. 85 (2024) 360-370), nanorods with a diameter of 45 nm, produced using a template with an interpore distance (IPD) of 110 nm, were successfully dispersed under conditions predicted by DLVO (Derjaguin-Landau-Verwey-Overbeek) theory. In this paper, we extend the investigation by exploring a broader range of IPD and diameter values. Our findings show that the nanorod diameter should be approximately 30% of the IPD for stable dispersion.
