Özet
In the development of polymer-based sorbents for the removal of organic and oil group pollutants, determining the interaction between surface chemistry and bulk structure is crucial. In this study, the effects of 3-aminopropyltriethoxysilane (APTES) and polydimethylsiloxane (PDMS) modifications on the adsorption behavior of the film in different pollutant environments were investigated. To explain the effect of surface functionalization and the diffusion pathways of the films on solvent, PVB films were produced at different thicknesses (0.2, 0.5, and 1.00 mm). While the sorption capacity increased with increasing thickness of PDMS-modified PVB surfaces, the opposite trend was observed in APTES-modified films. Both modification types showed higher sorption capacity compared to the unmodified PVB film, suggesting a relationship between interface chemistry and film properties. In the engine oil-water contaminant group, the highest sorption capacity was observed in the 1 mm thick PDMS-modified sample, reaching approximately 50 mg/cm2. The low-surface-energy wrinkled morphology created by the PDMS surface coating forms a compatible interface with non-polar contaminants, such as n-hexane, toluene, and engine oil. This study presents the properties of structures obtained through various modifications and provides an adjustable platform for the design of next-generation polymer-based sorbents optimized for selective solvent/oil adsorption.
