Investigation of different particle sizes on superhydrophobic surfaces made by rapid expansion of supercritical solution with in situ laser diffraction (RESS-LD)
In situ laser diffraction, scanning electron microscopy (SEM) imaging, and thermography have been used to investigate particle formation and particle size distribution of alkyl ketene dimer (AKD) produced by rapid expansion of supercritical solution (RESS). The investigated RESS process is based on an earlier reported method to prepare superhydrophobic coatings. Spray distance, pre-expansion tempe
