The adhesion energy between polymer thin films and self-assembled monolayers
نویسندگان
چکیده
A superlayer test has been adapted for the measurement of the fracture energy between epoxy thin films and self-assembled monolayers (SAM’s) on AuyTiySi substrates. The “arrest” mode of analysis has been shown to provide consistent results, particularly when relatively wide lines are used to encourage lateral decohesions. The fracture energy, Gi , of the interface between the monolayer and the epoxy is varied by adjusting the ratio of COOHyCH3 terminal groups. Connections among Gi, the surface energies, and the inelastic deformations occurring in the epoxy are explored upon comparison with interface crack growth simulations.

Wetting of Substrates with Phase-Separated Binary Polymer Mixtures
We investigate a wetting reversal transition in thin films of two-phase mixtures of poly(ethylenepropylene) (PEP) and its deuterated analog (dPEP) on substrates covered by self-assembled monolayers (SAM) whose surface energy, gSAM, is tuned by varying the SAM composition. As gSAM increases from 21 to 24 mJ m2, a transition from a dPEP PEP dPEP SAM to a dPEP PEP SAM structure occurs at increasin...
متن کاملProbing nanotribological and electrical properties of organic molecular films with atomic force microscopy.
Structural aspects of organic molecular films, such as disordering, packing density, molecular bending or tilts, and phase separation, influence electrical properties as well as friction and adhesion. This indicates a correlation between nanomechanical and charge transport properties of molecular films at the molecular scale. In this review, we highlight the recent studies on correlations betwe...
متن کاملSelf-assembled monolayers of polythiophene conductive polymers improve biocompatibility and electrical impedance of neural electrodes.
There is continued interest in the development of conductive polymer coatings to improve the electrical properties and biocompatibility of electrodes for neural prostheses. We present here a new type of coating, based on mixed self-assembled monolayers (SAMs) of thiolated poly(alkylthiophene)s and functionalized alkanethiols. When assembled as a SAM on electrodes designed for in vitro electroph...

The different methods of the nanopatterning of polymer layers, UV laser ablation, plasma depositing technique, electrochemical deposition and soft lithography are discussed as methods of surface patterning. The different surface functionalities are described, especially the effects of increased surface hydrophobicity/ superhydrophobicity created by coating substrates with low surface energy mat...
متن کاملSelf-assembled monolayers induced inter-conversion of crystal structure by vertical to lateral growth of aluminium doped zinc oxide thin films.
In this communication, we demonstrate the inter-conversion of crystal structure of aluminium doped zinc oxide (AZO) thin films from highly (002) plane oriented vertical growth to (103) plane oriented lateral growth by adjusting the polarity of the self-assembled monolayers (SAMs) on glass substrates at room temperature.
