Polymers at interfaces : Using atom transfer radical polymerization in the controlled growth of homopolymers and block copolymers from silicon surfaces in the absence of untethered sacrificial initiator
Krzysztof Matyjaszewski,Peter J. Miller,Nisha Shukla,Boonchuan Immaraporn,Andrew Gelman,Barry B. Luokala,Tiberiu Mircea Siclovan,Guido Kickelbick,Thomas Vallant,Helmuth Hoffmann,Tadeusz Pakula +10 more
TL;DR: The atom transfer radical polymerization (ATRP) of styrene and acrylates from silicon wafers modified with an initiator layer composed of 2-bromoisobutyrate fragments is described in this paper.
Journal ArticleDOI
Formation of Self-Assembled Octadecylsiloxane Monolayers on Mica and Silicon Surfaces Studied by Atomic Force Microscopy and Infrared Spectroscopy
Thomas Vallant,H. Brunner,Ulrich Mayer,Helmuth Hoffmann,T. Leitner,R. Resch,Gernot Friedbacher +6 more
TL;DR: The formation and growth of octadecylsiloxane monolayers on native silicon and mica substrates have been studied using atomic force microscopy, ellipsometry, and infrared spectroscop...
Journal ArticleDOI
Investigation of the Formation and Structure of Self-assembled Alkylsiloxane Monolayers on Silicon Using In Situ Attenuated Total Reflection Infrared Spectroscopy
TL;DR: In this article, the formation of alkylsiloxane monolayers on native silicon (Si/SiO2) was studied by means of in situ internal reflection IR spectroscopy (ATR) at the interface between a Si ATR crystal and the precursor solution.
Journal ArticleDOI
Substrate Effects on the Formation of Alkylsiloxane Monolayers
H. Brunner,Thomas Vallant,Ulrich Mayer,Helmuth Hoffmann,Bernhard Basnar,M. Vallant,Gernot Friedbacher +6 more
TL;DR: In this article, the adsorption rate and the submonolayer island morphology as a function of the substrate composition were investigated and two types of substrate effects were observed: an abrupt change of the shape, size, and height distribution of the sub monolayer islands between mica and SiO2-coated mica or silicon substrates.
Journal ArticleDOI
Investigations of the Growth of Self-Assembled Octadecylsiloxane Monolayers with Atomic Force Microscopy
Thomas Leitner,Gernot Friedbacher,Thomas Vallant,Helmuth Brunner,Ulrich Mayer,Helmuth Hoffmann +5 more
TL;DR: In this article, self-assembled monolayers of octadecylsiloxane were prepared and characterized by atomic force microscopy and ellipsometry and parameters, like residual water concentration of the solvent and the solution age, that affect both the surface coverage and the order of the film were investigated.
