Area of Science:

• Materials Science
• Nanotechnology
• Polymer Science

Background:

• Graphene exhibits superior properties, but commercial exploitation remains limited.
• Porous graphene (PG) shows potential for polymer composite fibers, yet its incorporation is challenging.
• Existing polymer-graphene composites often face low production rates and yields.

Purpose of the Study:

• To develop a high-yield method for incorporating porous graphene into polymer microfibres.
• To investigate the structural integrity and properties of porous graphene-polycaprolactone composites.
• To demonstrate the potential of these composite fibers for practical applications.

Main Methods:

• Fabrication of graphene-loaded polycaprolactone microfibres via a high-output manufacturing process.
• Characterization using scanning electron microscopy (SEM), Raman spectroscopy, FTIR, and X-ray diffraction (XRD).
• Analysis of fibre diameter and porous graphene content (3-5 wt%).

Main Results:

• Successfully produced microfibres with diameters ranging from 3-8 μm.
• Confirmed the presence of single-layer graphene structures within the polymer matrix using multiple analytical techniques.
• Demonstrated a high production rate and yield for the porous graphene-polymer composite fibres.

Conclusions:

• Porous graphene can be effectively integrated into polycaprolactone fibres through a scalable manufacturing process.
• The resulting composite fibres possess desirable structural characteristics for advanced applications.
• This work paves the way for the widespread use of porous graphene in electrical and ultrafiltration systems.
