Effect of fractional fluorination on the properties of ATRP surface-initiated poly(hydroxyethyl methacrylate) films

Article Abstract:

The conclusions regarding both the kinetics of film fluorination and the effect of fluorocarbon groups on film properties are developed by the dynamics of the acylation of poly(hydroxyethyl methacrylate) (PHEMA), with fluorinated acid chlorides. The methods for controlling the time of exposure for PHEMA films with the fluorinated acid chlorides are explained using these film propertie

Structure, wettability, and electrochemical barrier properties of self-assembled monolayers prepared from partially fluorinated hexadecanethiols

Article Abstract:

The preparation and characterization of self-assembled monolayers (SAMs) derived from the adsorption of partially fluorinated hexadecanethiols [CF3(CF2)(sub n-1)(CH2)(sub m)SH; n=2,4,6 and 8; n + m = 16)] onto the surface of gold is reported. The dielectric constants of the flurocarbon and hydrocarbon regions of these SAMs were quantified as ~1.7 and ~2.3 respectively.

Modification and stability of aromatic self-assembled monolayers upon irradiation with energetic particles

Article Abstract:

Ion and electron irradiation of self-assembled monolayers (SAMs) of 2-(4'-methyl-biphenyl-4yl)-ethanethiol, phenyl mercaptan (PEM), and 4'-methyl-biphenyl-4-thiol deposited on Au(111) substrates are studied. The results presented for the PEM/Au and BP2/Au systems show that the process is very sensitive to the structure of the SAM.
