Summary
Magnetic iron oxide nanoparticles enhance the thermal stability and shape memory properties of polymer nanocomposite films. These advanced PLA-PEG blend/MNP films also demonstrate antimicrobial activity against Candida albicans.
Area of Science:
- Materials Science
- Polymer Science
- Nanotechnology
Background:
- Magnetic nanoparticles (MNP) offer diverse applications.
- Shape memory polymers (SMPs) are advanced functional materials.
- Poly(lactic acid)-poly(ethylene glycol) (PLA-PEG) blends are widely studied SMPs.
Purpose of the Study:
- To investigate the impact of magnetic Fe3O4 nanoparticles (MNP) on PLA-PEG blend nanocomposite films.
- To evaluate the thermal stability, morphology, magnetic behavior, shape memory properties, and antimicrobial activity of these nanocomposites.
Main Methods:
- Nanocomposite films prepared via solution casting with varying MNP ratios.
- Characterization using ATR-IR, TGA, DSC, SEM, and VSM.
- Antimicrobial activity assessed using the disk diffusion method.
Main Results:
- MNP incorporation improved the thermal stability of PLA-PEG blend films.
- SEM and VSM confirmed successful MNP dispersion and magnetic properties.
- PLA-PEG blend/MNP nanocomposites exhibited enhanced shape memory properties and inhibited *C. albicans* growth.
Conclusions:
- Magnetic Fe3O4 nanoparticles effectively enhance the properties of PLA-PEG blend nanocomposites.
- These nanocomposites show potential for applications requiring thermal stability, magnetic responsiveness, and antimicrobial activity.
