Experimental and Modeling of Sulfonation of Styrene‐Based Resins Crosslinked With DVB and TMPTA

Chemical Engineering &Technology, Volume 48, Issue 6, June 2025.
This study explores how reaction conditions influence the performance of sulfonated styrene resins cross‐linked with DVB and TMPTA. Results show that tuning parameters like temperature and solvent swelling significantly enhances sulfonic group incorporation, especially in TMPTA‐based resins. Modeling reveals key structural differences and insights into

Atrazine removal by covalent bonding to piperazine functionalized PolyHIPEs

Science of The Total Environment, 2007
The removal of atrazine from water by a solid phase extraction technique using insoluble polymers is described. Porous crosslinked polymers bearing piperazine moieties were prepared in a one step reaction from the precursor 4-nitrophenylacrylate incorporating polymers (PolyHIPE type prepared by the polymerization of the continuous phase of a high ...

Tailoring Cell Attachment onto Melt Electrowritten Scaffolds via a Phase Separated Hydrogel Coating with Peptide Functionalization

Advanced Materials Interfaces, Volume 12, Issue 6, March 16, 2025.
A fast and flexible hydrogel coating process is demonstrated that applies to high resolution 3D printed materials. Using a phase‐separated system, drops of monomer/polymer are entrapped onto PCL fibers and functionalized with cell‐adhesive peptides. The modified material shows improved cell attachment, demonstrating the viability of a simple coating ...
