Fabrication of Robust Hydrophobic and Super‐Hydrophobic Polymer Films with Onefold or Dual Inverse Opal Structures

Hydrophobic and super‐hydrophobic materials have many important applications, but most of the artificially hydrophobic and super‐hydrophobic surfaces suffer from poor durability. Herein, a facile method is reported to fabricate robust hydrophobic and super‐hydrophobic polymer films through backfilling the silica colloidal crystal templates with the mixture of fluoropolymer, thermoset hydroxyl acrylate resins, and curing agent. After removal of the template, 3D ordered porous structures are obtained. The obtained polymer films have not only excellent hydrophobic or super‐hydrophobic properties but also good stability against temperatures, acids, and alkalis. Dual ordered porous structure can obviously enhance the hydrophobicity of polymer films compared to unitary one.

     

Hydrophobic and superhydrophobic surfaces from polyphosphazenes

Hydrophobic polymers play a crucial role in many biomedical and commercial applications. Hydrophobic polyphosphazenes offer opportunities for the tuning of surface properties that are not found for many conventional hydrophobic materials. Thus, changes in the side groups linked to the polyphosphazene skeleton allow the surface character to be changed from highly hydrophilic to hydrophobic. The hydrophobic side groups range from fluoroalkoxy groups to aryloxy and organosilicon units. Moreover, the polymer architectures can be varied from single‐substituent species to mixed substituent polymers or to block or comb copolymer structures. Superhydrophobicity, with contact angles to water as high as 159°, has been achieved by electrospinning a fluoroalkoxy derivative to nanofiber mats.

Hydrophobic coagulation of alumina slurries

This study reports a new wet forming method by hydrophobic modification of short-chain anionic dispersants. The influence of the content and type of hydrophobic chains on the rheology of alumina slurries, the drying shrinkage rates of wet bodies, the density and strength of the green bodies, and the density and microstructure of the resultant ceramics were intensively investigated. It is revealed that hydrophobic modification can endow short-chain dispersants with coagulation ability, when 0.3 wt% short-chain PIBM (a copolymer of isobutylene and maleic anhydride) was combined with 0.1 wt% TMAC (tetramethylammonium chloride), solid loading of the slurry was increased to 58 vol% and the slurry can coagulate to a wet green body in a short time. The resultant green body showed a uniform microstructure and was successfully sintered into translucent ceramics.     

Phenomena and Modeling of Hydrophobic Interaction Chromatography

Comprehension of the mechanisms of hydrophobic interaction chromatography is not as deep as for other chromatographic steps. This article shows the combination of modeling and experimental model parameter determination. Original mammalian cell culture is applied for validation instead of often-used test systems with for example, three pure proteins. This approach can have a huge benefit for process development and optimization of production processes under project conditions. To simulate the separation by hydrophobic interaction chromatography, a distributed plug flow model with inner pore diffusion is applied. The needed model parameters are determined by small scale experiments on a 1 ml column to reduce feed amount consumption and experimental procedure. Effects caused by system setup are optimized in relation to the volume. Gradient experiments are performed for the determination of isotherm parameters. The model parameters determined are experimentally validated at different set-ups of operation parameters as well as scaled up to 10 ml columns. The practicability of the proposed stepwise procedure of physico-chemical modeling in combination with laboratory scale experiments for the prediction of separation performance of original mammalian cell culture is proved. A model parameter determination directly with fermentation mixture is as well feasible.
