Membrane Polymers for the Pervaporative Separation of Polar Organics: Methanol and Acetonitrile

Journal of Applied Polymer Science, EarlyView.
We tested seven polymers as membranes for the pervaporative separation of methanol‐acetonitrile mixtures. Chloroprene rubber, silicone rubber, and Matrimid showed effective separation by favoring acetonitrile transport, enabling azeotrope breaking. Plasticization was assessed using Broadband Dielectric Spectroscopy.

Polymer‐Crosslinking System‐Filler Interactions in Polychloroprene Adhesives: Experimental and Molecular Modeling Insights

Journal of Applied Polymer Science, EarlyView.
The use of polychloroprene is common in elastomeric adhesives. This study highlights the possible substitution of zinc oxide curing systems to a less hazardous metal complex, also evaluating the changes that higher surface area fillers can bring to the adhesive.

Glyoxylic‐Acetal‐Based Gel‐Polymer Electrolytes for Lithium‐Ion Batteries

Batteries &Supercaps, Volume 8, Issue 3, March 2025.
A safe electrolyte based on tetraethoxyglyoxal (LE) is combined with a methacrylate polymer matrix. The resulting gel‐polymer electrolyte (GPE) exhibits an increased flash point, suitable ionic conductivity, and a stable performance in lithium‐ion battery cells.
