Effect of Surface Modification on Equilibrium Kinetics under Nanopore-Confinement: Application of the Material Time Concept - research data

Description:
The glass-forming silicone liquid DC704 confined in anodic aluminum oxide (AAO) nanopores was used to investigate equilibrium kinetics under nanoscale confinement. To this end, a series of experiments were performed, including dielectric spectroscopy, differential scanning calorimetry (DSC), atomic force microscopy (AFM) measurements, and contact angle characterization. These measurements aimed to investigate the influence of pore size, surface modification (SiO₂ or Al₂O₃ ALD coatings), and thermal treatment on the equilibration dynamics of nanopore-confined DC704.
The dataset includes:
• Raw dielectric spectroscopy data, providing both temperature-dependent scans and time-dependent relaxation measurements of the complex permittivity (ε′ and ε″) for DC704 confined in AAO nanopores.
• Raw DSC temperature-scan data for DC704 in 50 nm and 100 nm AAO nanopores with different surface coatings.
• AFM adhesion measurements, providing insight into surface–liquid interactions.
• Contact angle measurements with water and glycerin to characterize wetting properties of modified and unmodified nanopores.
• Detailed procedural information on the preparation of nanopore-confined DC704 samples.
These data were used in the publication:
