Rigid fractal networks of polymer nanoparticles several tens of nanometers in size are obtained through irreversible aggregation immediately following nanoprecipitation from dilute polymer solutions. These networks are useful as precursors for the fabrication of pressure-resistant ultrafiltration membranes with a sharp cut-off of less than 5 nm and an extremely high water flux.

Poly(vinylidene fluoride-co-chlorotrifluoroethylene) (PVDF-CTFE) membranes are used in different applications such as sensors, actuators, and battery separators. In this work, the variations of its microstructure have been investigated as a function of polymer concentration and evaporation solvent temperature. These microstructures are correlated through the phase diagrams for the binary system (PVDF-CTFE/DMF system) obtained by the Flory-Huggins theory. For PVDF-CTFE membranes, the β-phase content, thermal and mechanical properties depend on the initial polymer concentration and solvent evaporation temperature.
- Competitive permeation of gas and water vapour in high free volume polymeric membranes
Colin A. Scholes, Jianyong Jin, Geoff W. Stevens and Sandra E. Kentish
Article first published online: 4 MAR 2015 | DOI: 10.1002/polb.23689
The solubility and permeability of water through poly (1-trimethylsilyl-1-propyne) (PTMSP) and polymer of intrinsic porosity (PIM-1) membranes were studied. The water permeability through both polymers was comparable and found to be at a minimum at 80 °C for PTMSP and 70 °C for PIM-1. Introducing water vapour reduced both CO2 and N2 permeabilities. A modified dual mode sorption model indicated that water swelled PTMSP, while for PIM-1, filling of the micro-voids with water hampered diffusion.
- Monitoring of the shrinkage during the photopolymerization of acrylates using hyphenated photorheometry/near-infrared spectroscopy
Christian Schmidt and Tom Scherzer
Article first published online: 4 MAR 2015 | DOI: 10.1002/polb.23694
This article describes a new method for the simultaneous determination and time-resolved monitoring of the polymerization shrinkage by rheometry and the conversion by near-infrared spectroscopy during UV photopolymerization reactions. Quantitative shrinkage values of acrylates and nanocomposites were found to be in excellent correlation with data that were determined by an independent method.
- Orientation control in nanoparticle filled block copolymer cold zone annealed films

Addition of a low concentration (1–3 wt %) of 4-hydroxythiophenol coated cadmium sulfide semiconductor nanoparticles (NPs) leads to an orientation flip from vertical to parallel-to-substrate cylinders in zone annealed cylindrical block copolymer (c-BCP) thin films. The effect is attributed to hindering of long-range order of c-BCP by NPs, which is limited in the vertical direction by thickness. However, increasing the zone annealing sweep rate imposes a higher intensity gradient strain field, partially restoring the vertical order in NP filled films.
