2. 1. Stabilizers in crosslinked polydimethylsiloxane

   Author : Kamyar Fateh-Alavi; KTH; []
   Keywords : Polymer; Material Science; Polydimethylsiloxane; Stabilizers;

   Abstract : The loss and recovery of the surface hydrophobicity areimportant phenomena when highvoltage insulators, with a shedmaterial composed of polydimethylsiloxane (PDMS), are used. Theloss of hydrophobicity is mostly due to the oxidativecrosslinking which takes place on the PDMS surface duringexposure to electrical discharges, e. g. corona discharges. READ MORE

7. 5. Properties of stabilizers in colloidal dispersions

   Author : Catherine Boissier; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; surfactants; conformation; polymers; NMR relaxometry; exchange dynamics; residence times; adsorption; polymer-surfactant interaction; NMR diffusometry;

   Abstract : Surfactants and polymers are frequently used as stabilizers in colloidal dispersions. Depending on their solubility and the interactions in their local environment, their tendency to remain adsorbed on a surface will differ. READ MORE
