Sept 12, 2018Spontaneous synthesis of homogenous polymer networksNagoya researchers developed a spontaneous polymer network synthesis that allowed for the preparation of gels containing narrow molecular weight distribution polymers. The gel networks showed swelling properties that were responsive to temperature and solvent concentration. The reported process demonstrates the potential for facile preparation of high quality materials that exhibit the full range of polymer gel properties, including sustained release, stimuli responsiveness, and molecular sieving, amongst others.
Polymer gel materials have been widely applied in medicine, civil engineering, architecture and space exploration. Their appeal lies in the potential for preparing functional materials with consistent properties, via simple and easily reproducible methods. However, the compromise between method simplicity and optimized material performance means that not all gel materials fulfill their potential. Now a group of researchers at Nagoya University has established a process that combines the ease of a spontaneous process with the high molecular weight control required for producing high-performance materials. Their findings were published in NPG Asia Materials.

Now, researchers from Canada have synthesized a phosphonium polymer that challenges this view. As outlined in the journal Angewandte Chemie, their polymer salt contained no hydrophobic alkyl chains but still acted as an extraordinarily efficient biocide. A re-evaluation of established strategies in antibiotics polymer research might be necessary.
To combat multiresistant bacteria and discover new antibiotics, scientists increasingly turn to the design and exploration of short artificial polymers. As these polymers can mimic the powerful peptide antibiotics, Paul J. Ragogna and Beth Gillies at Western University, London, ON (Canada), and their groups focus on phosphorus-containing polymers, the polyphosphoniums. Their molecular structure consists of a hydrocarbon backbone and a positively charged phosphorus center in every repeat unit. A balanced display of hydrophobic alkyl chains and positive charges was considered essential for effective adhesion to bacterial cells and membrane disruption. Envisaging still more effective cell lysis, the scientists started to fine-tune this amphiphilic nature of the polyphosphoniums.
