Poly(vinylidene fluoride-co-trifluoroethylene)/poly(hydroxyethyl acrylate), P(VDF-TrFE)/PHEA membranes, that are suitable for applications such as battery separators, filtration membranes and cell culture supports have been investigated as a function of amounts of ethanol, added to the polymerizing mixtures. The membrane is capable of absorbing the monomer HEA after immersion in the monomer for long periods and even mixtures of HEA with ethanol. FT-IR, DSC, cryo-SEM, equilibrium water content and contact angel measurement were performed for membrane characterization in function of amount of ethanol.
- A complete TSDC description of molecular mobilities in polylactide/starch blends from local to normal modes: Effect of composition, moisture, and crystallinity

The dielectric relaxations of the immiscible blends PLLA/starch are studied for different motion scales and their variation in the presence of moisture which acts as a plasticizing agent on the starch bimodal segmental dynamics. The PLLA normal mode, which is the longest one and is caused by the fluctuations of end-to-end chain length, is observed in the presence of starch inclusions but is not detected as crystallinity and interfacial charge accumulation sets in.
- Oscillatory shear-induced alignment of ketjen black conductive particles in polylactic acid and its effect on the electrical anisotropy
Liangyao Su, Pengfei Wang, Zhongbin Xu, Mao Peng and Dong Chen

Ketjen black (KB) exhibits a high specific surface area and branched structure, but it is difficult to align in a polymer matrix. However, KB conductive particles are well aligned along a preferred direction in polymer matrix under oscillatory shear. When aligned, a large electrical anisotropy is observed in the polymer composite.
- How molecular internal-geometric parameters affect PB-PEO polymersome size in aqueous solution

The diameter size distributions of polymersomes based on polybutadiene polyethylene oxide with high f / low Mn and mixed diameters, high f / high Mn and mainly large diameters, and low f and mainly small diameters were measured using dynamic light scattering and freeze-fracture transmission electron microscopy. In the last region, the poylmersomes are highly polydisperse, containing many highly varying diameters. Furthermore, there is a tendency towards increased diameter with increasing f and Mn. These findings can facilitate the cost-efficient upscaling of polymersome production.
- Degradation of a polyester-urethane coating: Physical properties

Degradation of polyester-urethane coatings by radiation leads to changes in chemistry and crosslink density and, hence, in properties. In the glassy state, the appearance of oxidized segments dominates, resulting in stronger interactions and therefore a reduced volume and tensile stress in the coating. In the rubbery state, the lower crosslink density is the dominating factor, resulting in an increased thermal expansion coefficient so that the coating experiences a compressive stress.
