Carbon-Bridge Incorporation in Organosilicate Coatings Using Oxidative Atmospheric Plasma Deposition
Carbon-bridges were successfully
incorporated into the molecular
structure of inorganic silicate films deposited onto polymer substrates
using an oxidative atmospheric plasma deposition process. Key process
parameters that include the precursor chemistry and delivery rate
are discussed in the context of a deposition model. The resulting
coating exhibited significantly improved adhesion and a 4-fold increase
in moisture resistance as determined from the threshold for debonding
in humid air compared to dense silica or commercial sol–gel
polysiloxane coatings. Other important parameters for obtaining highly
adhesive coating deposition on oxidation-sensitive polymer substrates
using atmospheric plasma were also investigated to fully activate
but not overoxidize the substrate. The resulting carbon molecular
bridged adhesive coating showed enhanced moisture resistance, important
for functional membrane applications
