Summary
This study investigated water sorption and desorption in composite resins. Higher filler content reduced water absorption rates, aligning with mixture law predictions for sorption but not desorption.
Area of Science:
- Materials Science
- Polymer Chemistry
- Biomaterials
Context:
- Composite resins are widely used in dental and industrial applications.
- Understanding water interaction is crucial for material longevity and performance.
- Both chemically-cured and light-cured composites were analyzed.
Purpose:
- To investigate the influence of filler content on water sorption/desorption.
- To determine diffusion coefficients for water sorption and desorption.
- To compare experimental results with the law of mixtures predictions.
Summary:
- Water sorption and desorption rates decreased with increased filler content in composite resins.
- Filler content influenced water sorption diffusion coefficients according to the law of mixtures.
- Water desorption diffusion coefficients showed a different trend, exceeding sorption coefficients by over two times.
Impact:
- Provides insights into the water absorption behavior of composite resins.
- Informs material selection and design for applications requiring water resistance.
- Highlights differences in water sorption versus desorption mechanisms in composites.
