Area of Science:

• Materials Science
• Nanotechnology
• Electrochemistry

Background:

• Metal-organic frameworks (MOFs) offer tunable porosity and high surface area.
• Electrospun fibrous membranes provide flexible substrates for energy devices.
• Polyaniline (PANI) is a conductive polymer with potential in energy storage.

Purpose of the Study:

• To create a novel composite membrane for wearable energy-storage applications.
• To integrate UiO-66 MOF crystals and polyaniline (PANI) onto poly-cyclodextrin (poly-CD) fibrous membranes.
• To evaluate the performance of the PANI@UiO-66/poly-CD membranes as free-standing electrodes.

Main Methods:

• Growing UiO-66 MOF crystals on electrospun crosslinked poly-cyclodextrin (poly-CD) fibrous membranes.
• Confining polyaniline (PANI) within the UiO-66 MOF pores.
• Fabricating free-standing electrodes from the PANI@UiO-66/poly-CD composite membranes.

Main Results:

• Achieved ultrahigh coverage of UiO-66 crystals on the poly-CD fibrous membranes.
• Successfully confined PANI within the MOF pores, creating a PANI@UiO-66/poly-CD composite.
• Demonstrated the potential of the composite membranes as effective free-standing electrodes for wearable energy-storage devices.

Conclusions:

• The PANI@UiO-66/poly-CD composite membranes show promise for next-generation wearable electronics.
• The integration of MOFs and conductive polymers on fibrous membranes is a viable strategy for energy storage.
• This work advances the development of flexible and high-performance energy-storage solutions.
