Application

  • Superhydrophobic Surface Coating: Studies the application of hexamethyldisiloxane coatings on fabric masks via plasma treatment to achieve superhydrophobic properties, enhancing the masks′ resistance to moisture (M Prado et al., 2022).
  • PECVD for Thin Film Coatings: Describes the use of hexamethyldisiloxane in plasma-enhanced chemical vapor deposition to create thin film coatings, exploring the effects of using extremely asymmetric capacitive RF discharge (Ž Gosar et al., 2020).
  • QCM-Based VOC Sensors: Hexamethyldisiloxane thin films are used as sensitive coatings for quartz crystal microbalance sensors, enhancing their capability to detect various volatile organic compounds (M Boutamine et al., 2014).
  • Hydrophobic-Hydrophilic Films: Explores the polymerization of hexamethyldisiloxane using atmospheric pressure plasma jets to create films with tailored hydrophobic and hydrophilic properties (M Bashir, S Bashir, 2015).
