Spontaneous Polymer Thin Film Assembly and Organization Using Mutually Immiscible Side Chains

Abstract: Polymer ultrathin film self-assembly and organization on solid substrates has been directed using grafted siloxane copolymers bearing mutually immiscible alkyl and perfluoroalkyl side chains. Polysiloxanes grafted with both alkyl disulfide and perfluoroalkyl side chains have been synthesized and characterized. These terpolymer systems assemble spontaneously on gold surfaces, forming bound polymeric monolayers organized by intramolecular phase separation. Interfacially bound polymer monolayer fabrication is dri… Show more

“…The higher the hydrophobicity of film surface is, the higher the contact angle is. As mentioned before, the fluorine-containing polymers have good hydrophobic property and fluorine atoms have a strong tendency to spread to and locate on the film surface during the film formation [12][13][14]. Hence, when cured to form films, it is expected that the fluorine-containing groups in the FPAER-SIPNs tend to move towards the film surface, and consequently impart the surface hydrophobic function to some extent (Fig.…”

“…In fact, a conventional commodity polymer with a thin layer of perfluorinated groups rich in surface might achieve excellent surface properties. It is well known that the fluorinated groups, especially the pendant -CF 3 end groups on the perfluoroalkyl groups, have the tendency to migrate toward and preferentially locate at the outermost layer of the polymer-air interface to minimize the interfacial energy [12][13][14]. Consequently, the incorporation of the fluorinated groups into a suitable organic medium can not only decrease the cost of manufacturing fluorinecontaining polymer, but also get a fluorinated surface on a cheaper bulk organic film with excellent surface properties.…”

“…[17][18][19][20][21][22] In particular, the covalent attachment for irreversible grafting can be accomplished by either "grafting-onto" [17][18][19] or "grafting-from" approach. [20][21][22][23] The grafting-from approach, surface-initiated polymerization, is a reliable method to achieve tunable and robust polymer brushes and to control their grafting density a͒ Author to whom correspondence should be addressed.…”
