@kimlockhartga 🧵 a #polymer: https://en.wikipedia.org/wiki/Polymer Polymers are large compounds of macromolecules, therefore great to "build" something. We have natural and artificial polymers: Your DNA or coton fibres are made from polymer as well as a plastic bottle.

We mostly built stuff with artificial polymers because they were cheap and very easy to engineer since the 1950s. With the problem of plastic waste, engineering seeks more and more for natural polymers.

Polymer Skins That Change Color and Texture When Exposed to Water

Although the paper itself is sadly paywalled with no preprint available, it’s fairly easily summarized and illustrated with details from the Supplementary Data section. The polymer used is poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (<a href="https://en.wikipedia.org/wiki/PEDOT:PSS" target="_blank">PEDOT:PSS</a>), which when exposed to an electron beam (electron-beam lithography) undergoes certain changes that become apparent when said water is added.</p>
<p>The polymer is hygroscopic, but the electron beam modifies the extent to which a specific area swells up, thus making it possible to create patterns that depend on the amount of electron beam exposure. In order to ‘colorize’ the polymer, complex cavities are created that modify the angular distribution of light, as illustrated in the top image from the Supplemental Data <code>docx</code> file.</p>

#Neuralnetwork finds an #enzyme that can break down #polyurethane
A completely new enzyme that researchers developed to break down polyurethane, the #polymer commonly used to make #foam cushioning, among other things. The new enzyme is compatible with an industrial-style recycling process that breaks the polymer down into its basic building blocks, which can be used to form fresh polyurethane.

Researchers have created a #polymer “Chinese lantern” that can snap into more than a dozen curved, three-dimensional shapes by compressing or twisting the original structure. This rapid shape-shifting behavior can be controlled remotely using a magnetic field, allowing the structure to be used for a variety of applications.

Maybe chemical adulthood begins when you realize nomenclature is really important. Anyway, IUPAC is seeking feedback on draft refinements of how polymerization reactions are named. The draft is here
https://iupac.org/wp-content/uploads/2025/08/PAC-REC-2025-0490.R1_PR20250813.pdf
And feedback can be submitted here
