Palygorskite@Fe₃O₄@polyperfluoroalkylsilane nanocomposites for superoleophobic coatings and magnetic liquid marbles

Abstract

Magnetic palygorskite@Fe3O4@polyperfluoroalkylsilane nanocomposites were prepared, which can be used for fabricating superoleophobic coatings and magnetic liquid marbles.

The Potential of Liquid Marbles for Biomedical Applications: A Critical Review

“…One of the most common means for manipulation of LM is the use of magnetic forces. Its popularity is owed to the simplicity of use and the remote control (no physical contact required) – Figure A . There is two means to confer magnetic response in LM: a magnetic coating or a magnetic content …”

“…For the coating, the used particles are hydrophobic nanoparticles of iron (Fe 3 O 4 ) or synthesized nano/microparticles combining iron and other materials . Some of these synthesized microparticles were produced using biocompatible materials which opens the possibility to use them in biomedical applications, being an example of the magnetic superhydrophobic cellulose‐based microspheres developed by Lin et al Fundamentally, the iron is used to confer superparamagnetic properties to the coating particles, making possible the LM manipulation by using an external magnetic field – Figure A.…”

Attapulgite: from clay minerals to functional materials

Rapid fabrication of robust, washable, self-healing superhydrophobic fabrics with non-iridescent structural color by facile spray coating

“…Hydrophobicity of the lm showed better improvement tendency as the treatment temperature reached 90 C. 62 Surface energy and surface roughness has synergetic effect on the improvement of hydrophobicity of the fabric surface. 63 We could see from the images obtained using atomic force microscopy (AFM) (Fig. S9 †) that the surface of the resulting ber had a root mean square (RMS) roughness as high as 40 nm since quasi-amorphous structures created by spray-coating enhanced the surface roughness of the coated fabrics.…”
