Polymer corrugated

Both hollow pyramids and corrugated pyramids are thoroughly documented and fairly well understood. Such structures are consistent with the notion that successive layers of folded chains do not fold at the same place, but offset this fold stepwise to generate the pyramid face. The polymer chains are perpendicular to the planar faces of the pyramid and are therefore tilted at an angle relative to the base of the pyramid.

Another important feature of polymer adsorption is the influence exerted on it by the surface roughness. Ball et al. [22] proposed that if the surface potential is not attractive enough to bind the polymer when flat, then corrugation can aid binding as follows. For a sinusoidal corrugation, one might anticipate that some...

The bilayer morphology of thin asymmetric films of may be unstable. A regularly corrugated surface structure of the films was ascribed to spinodal transition into a laterally phase separated structure, where the surface morphology depended on the polymer incompatibility and the interfacial interactions [347, 348]. Recently, the phase separation and dewetting of thin films of a weakly incompatible blend of deuterated PS and poly(p-methylstyrene) have been monitored by SFM [349, 350]. Starting from a bilayer structure, after 454 h at T= 154 °C the film came to the final dewetting state where mesoscopic drops of... 

Leznoff and co-workers reported the structural characterization and the polymorphic nature of a gold(I)-copper(II) coordination polymer, [Cu Au(CN)2 2(dmso)2] 00 [125]. In a green polymorphic form it possessed a 1-D chain structure with five-coordinate copper(II) centers, while a 2-D corrugated sheet structure with six-coordinate copper(II) centers was characterized in the blue polymorph, both of which are linked together to form a 3-D structure via aurophilic interactions. These two polymorphs exhibited virtually identical vapochromic behavior towards water, MeCN, dioxane, dmf, pyridine and ammonia, with the formation of [Cu Au(CN)2 2(solvent)x]oc,.

The work on the stability of polystyrene films on corrugated substrates has shown to us that the wetting and stability of polymer films thinner than the chain size is a very poorly understood subject. There have also been similar studies on flat substrates, but a key issue is likely to be the conformation of polymer chains close to surfaces. Scattering experiments have not yet lead to a clear answer to this question, despite several experiments being per-formed. " " Theoretically, the issue is also open. We expect that in the next few years this issue will be resolved, probably by neutron or X-ray scattering experiments.
