Superfine particles from eggshell membrane blended with medical polyurethane created novel nanofibers. These collagen-rich, hydrophilic nanofibers show promise for applications in facial masks, wound dressings, and drug delivery.
Area of Science:
- Biomaterials Science
- Nanotechnology
- Polymer Science
Background:
- Eggshell membrane is a natural biomaterial rich in collagen, offering potential for tissue regeneration.
- Developing advanced materials from natural sources requires effective processing techniques like electrospinning.
- Medical grade polyurethane (MPU) is a biocompatible polymer suitable for biomedical applications.
Purpose of the Study:
- To create blend nanofibers from soluble eggshell membrane superfine particles (SP) and medical grade polyurethane (MPU).
- To regenerate the natural fiber-like structure of eggshell membrane using electrospun nanofibers.
- To evaluate the properties and potential applications of SP/MPU blend nanofibers.
Main Methods:
- Electrospinning of different blend ratios of SP/MPU suspensions.
- Characterization of nanofiber morphology, dispersion, and diameter.
- Assessment of mechanical properties (tensile strength, tensile resilience) and surface properties (hydrophilicity, water contact angle).
Main Results:
- SP were randomly dispersed in MPU nanofibers without agglomeration for SP content < 20 wt%.
- Blend nanofibers exhibited excellent tensile strength and resilience comparable to pure MPU nanofibers.
- Blend nanofibers became fully hydrophilic with a water contact angle of 0°.
Conclusions:
- SP/MPU blend nanofibers successfully regenerated a natural fiber-like structure.
- The blend nanofibers possess desirable mechanical and hydrophilic properties.
- These nanofibers are suitable for applications in facial masks, wound dressings, and pharmaceutical carriers due to their collagen content and hydrophilicity.
