This study aims to control the microstructure of Shirasu glass thin films for excellent anti-fogging properties by integrating experimental analysis with numerical simulations to elucidate the underlying physical processes.The scientific novelty is the first-time application of the 1958 Cahn-Hilliard equation in our lab to successfully simulate spinodal decomposition. Aided by an LLM, these simulations provided a physical explanation for a previously empirical process.The data revealed that the initial component concentration is the dominant parameter determining the final structure, while the equation's coefficients show that intrinsic material properties are also influential. This opens new avenues for predicting pore size based on a scientific understanding of sputtering and spinodal phenomena.This research establishes a pathway for physics-based process optimization, moving beyond trial-and-error, and serves as a practical example of applying LLMs in materials engineering.
