“…PK-based and derived polymers have been used to produce microporous membranes entailed with antifouling properties, [5,6] chemical resistance, [7,8] for the microfiltration and purification of water from both chemical and biological contaminants. In recent years, the simple aliphatic PK chain (both derived from ethylene/CO copolymerization or ethylene/propylene/CO terpolymerization) has been modified through either radiation grafting copolymerization [9,10] or Paal-Knorr cyclization reaction with functionalized primary amines. [11] The latter strategy for PK functionalization occurs without the need for radiation or additional catalysts, introducing pyrrole moieties in the backbone with pendant functional groups.…”

New inorganic-organic hybrid anion exchange membranes are produced after incorporation of tantalum oxide into trimethylammonium-functionalized polyethylene pyrrole-co-polyethylene ketone (functionalized polyketone, FPK), obtained by the chemical modification of a polyketone polymer. The influence of tantalum oxide fillers on the properties of the synthesized membranes is investigated. The interaction between inorganic fillers and the polymer chains is studied using Attenuated Total Reflectance Fourier Transform Infrared Spectroscopy (ATR-FTIR). The thermal analysis of the FPK membranes reveals they are thermally stable at up to 250°C. However, the incorporation of the inorganic fillers reduces the thermal stability. Modulated Differential Scanning Calorimetry (MDSC) results indicate that the inclusion of inorganic fillers leads to an increase in crystallinity. This study reports that the properties of the bulk polymer can be tuned by controlling the degree of functionalization and content of inorganic fillers, as confirmed by Near Ambient Pressure X-Ray Photoelectron Spectroscopy (NAP-XPS) studies. Finally, Broadband Electrical Spectroscopy (BES) studies demonstrate that the hybrid membranes are characterized by several polarization phenomena contributing to the overall ion conductivity of the material, which at RT is of 1.46 and 1.61 mS cm −1 for the FPK cast membrane and the hybrid membrane with 5.0 wt.% of Ta 2 O 5 filler, respectively.

“…The gravimetric method was used to study the microsphere swelling ratio [26]. As expected, microspheres with varying reaction parameters showed a continuous decreasing in the swelling ratio when the temperatures was changed from 28 °C to 35 °C, induced by the thermally sensitive phase transition of the microspheres (Figure 4).…”

In recent years, thermosensitive poly(N-isopropylacrylamide) (PNIPAM) microspheres have received extensive attention due to their many advantages, and their size and swelling ratio are two crucial factors. In this paper, homogeneous and hollow thermosensitive microspheres were prepared by free radical polymerization in an aqueous solution. The effects of the process parameters on the size of the microspheres were studied. The results indicated that the change in size during reaction at different temperatures was not obvious. The size of the microspheres ranged from 802 ± 35.4 nm to 423 ± 33.7 nm with the changes in the dosage of the initiator. Meanwhile, it was observed that the size of microspheres was slightly reduced due to the increase of reaction time. When the dosage of methyl methacrylate (MAA) is increased, the size of the hollow microspheres increased by more than 110%. The average size of the microspheres was smaller when the content of sodium dodecyl sulfate (SDS) was 3 wt%. The microspheres with varying reaction parameters showed a continuous decreasing swelling ratio when the temperatures were changed from 28 °C to 35 °C. In comparison with homogeneous microspheres, the average swelling ratio of hollow microspheres was larger.
