Summary
A robust superamphiphobic sponge was created using a single initiated chemical vapor deposition (i-CVD) process. This durable material exhibits both superhydrophobicity and superoleophobicity for versatile applications.
Area of Science:
- Materials Science
- Surface Chemistry
- Nanotechnology
Background:
- Developing robust superamphiphobic surfaces is crucial for various applications.
- Existing methods often involve multiple steps or harsh conditions.
Purpose of the Study:
- To develop a robust superamphiphobic sponge (SA-sponge) using a facile single-step process.
- To investigate the properties and potential applications of the fabricated SA-sponge.
Main Methods:
- Utilized a single initiated chemical vapor deposition (i-CVD) process.
- Deposited poly(3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-heptadecafluorodecyl methacrylate) (PFDMA) onto a commercial sponge.
- Achieved conformal coating of PFDMA on both exterior and interior sponge surfaces.
Main Results:
- The fabricated SA-sponge exhibited both superhydrophobicity and superoleophobicity.
- The SA-sponge demonstrated robustness against physical and chemical damage.
- The material was successfully fabricated at nearly room temperature.
Conclusions:
- A facile and robust method for creating SA-sponges was established.
- The SA-sponge shows significant potential for multi-purpose applications, including gas-permeable liquid separation.
