Probing polymer/polymer interfaces.

چکیده
Infrared-visible sum frequency generation spectroscopy (SFG) has been used to study the interface between poly(vinyl-N-octadecylcarbamate-co-vinyl acetate) (Comb) and deuterated or hydrogenated polystyrene (dPS or hPS) films. Strong methyl symmetric and Fermi resonance bands associated with the alkyl side chains of the Comb polymer are observed in the SFG spectra. In addition, for Comb/hPS spectra, symmetric and asymmetric vibration modes of phenyl groups are observed. The presence of asymmetric modes indicates the phenyl rings are tilted with respect to the interface normal.

Molecular Level Studies of Polymer Behaviors at the Water Interface Using Sum Frequency Generation Vibrational Spectroscopy
Industrial plastics, biomedical polymers and numerous other polymeric systems are contacted with water for everyday functions and after disposal. Probing the interfacial molecular interactions between widely used polymers and water yields valuable information that can be extrapolated to macroscopic polymer/water interfacial behaviors so scientists can better understand polymer bio-compatibility...
متن کاملDirect measurement of the role of confinement and chemistry on local physical and mechanical properties of polymers
It has been demonstrated that the physical properties of the interfacial regime near the interfaces of polymers and inorganic inclusions can be signifi cantly altered because of the geometric and chemical interactions between the two constituents and the subsequent communication of those interactions through the macromolecular polymer network. The mechanical properties are expected to deviate f...

متن کاملOn the reflectivity of polymers: Neutrons and X-rays
Over the last few years reflectivity methods have emerged as key tools for the investigation of polymer surfaces and interfaces. The high spatial resolution of these techniques, of the order of 5 A, has provided a means of probing density gradients in polymers on a submolecular level. This resolution, coupled with selective labeling of all or parts of polymer chains has permitted the examinatio...
متن کاملDepinning of a Polymer in a Multi-interface Medium
In this paper we consider a model which describes a polymer chain interacting with an infinity of equi-spaced linear interfaces. The distance between two consecutive interfaces is denoted by T = TN and is allowed to grow with the size N of the polymer. When the polymer receives a positive reward for touching the interfaces, its asymptotic behavior has been derived in [3], showing that a transit...
