Summary
This study presents a novel, eco-friendly method for creating polymer-metal composite materials using plant-synthesized silver nanoparticles and electrospun polymer fibers. The resulting material shows promise for various biomedical applications due to its unique structure and properties.
Area of Science:
- Materials Science
- Nanotechnology
- Biomedical Engineering
Background:
- Polymer-metal composites with 3D structures are valuable for biomedical applications.
- Developing efficient and environmentally friendly methods for creating these materials is crucial.
Purpose of the Study:
- To develop a novel composite material using phytosynthesized silver nanoparticles (NPs) and electrospun polymer fibers.
- To evaluate the feasibility of using this composite for biomedical applications.
Main Methods:
- Silver nanoparticles (NPs) were synthesized using Tilia sp. leachate (phytosynthesis).
- These NPs were incorporated into poly(vinyl alcohol) (PVA) fibers via electrospinning.
- Material characterization included TEM, XRD, SEM with EDX, and ICP-AES.
Main Results:
- Crystalline silver NPs (14±9 nm) were successfully formed, stabilized, and encapsulated with minimal aggregation.
- Uniform electrospun PVA fibers (221±24 nm) containing silver NPs were achieved.
- Consistent silver concentration (approx. 0.28-0.30 wt.%) was confirmed across the material.
Conclusions:
- A simple, eco-friendly method for preparing polymer-metal composites with biomedical potential was established.
- The material's structure and the controlled release of silver NPs from the water-soluble PVA matrix highlight its effectiveness.
