Data on Applied Surface Science Reported by Researchers at Singapore National University (Hydrophobic to superhydrophobic surface modification using impacting particulate sprays)

By a News Reporter-Staff News Editor at Science Letter -- Investigators discuss new findings in Science. According to news reporting from Singapore, Singapore, by NewsRx journalists, research stated, "The roughening or structuring of inherently hydrophobic surfaces to possess microscopic and nanoscopic features can transform them to exhibit superhydrophobicity. The use of impacting particulate sprays here eschews specialized reagents and equipments; is simple, inexpensive, and rapid to implement; creates highly repeatable outcomes; and permits selective region transformation via simple masking."

The news correspondents obtained a quote from the research from Singapore National University, "With PTFE, the contact angle transforms from 90 degrees to 150 degrees, in which SEM examination reveals erosive wear mechanisms that are dependent on the impingement angle. The process tends to cause the sample to bulge upwards from the treated surface due to elongation there, and can be mitigated by using lower impingement angles in the particulate spray. A finite element model created enables this characteristic to be related to the action of locked-in surface traction forces. The use of adhesive bonding to a rigid base is shown to be an alternative method to reduce the bulging. A second finite model developed allows knowledge of the right adhesive needed for this."

According to the news reporters, the research concluded: "In developing substrates for biochemical analysis, the approach offers very small possibilities for unintended synergistic interactions."
