Background:

Liquid metal applications are hindered by polymer wetting on oxidized gallium-based liquid metals.
Developing non-wetting polymer surfaces is critical for advancing liquid metal technologies.

Purpose of the Study:

To investigate the effect of CF4/O2 plasma treatment on polymer surfaces for liquid metal applications.
To convert wetting polymer surfaces into non-wetting (lyophobic) surfaces for gallium-based liquid metals.

Main Methods:

Polymer surfaces (PDMS, SU8, S1813, polyimide) were treated with CF4/O2 plasma for 120 seconds.
Contact angle measurements (static, advancing, receding) were used to quantify wetting behavior.
X-ray photoelectron spectroscopy (XPS) and atomic force microscopy (AFM) analyzed surface chemistry and topography.

Main Results:

Plasma treatment resulted in contact angles >150° (static/advancing) and >140° (receding), indicating significant lyophobic behavior.
Surface analysis revealed simultaneous fluorination and a substantial increase in surface roughness (sub-micron scale).
The Cassie-Baxter state, driven primarily by roughness, was suggested as the mechanism for non-wetting properties.

Conclusions:

CF4/O2 plasma treatment effectively transforms wetting polymer surfaces into non-wetting ones for gallium-based liquid metals.
Surface roughness, augmented by plasma treatment, is the dominant factor in achieving lyophobic behavior.
This method offers a versatile approach to reduce surface free energy and enhance compatibility in liquid metal-polymer systems.
