Advanced Materials, EarlyView.The mechanical performance of nanocellular polyetherimide cannot be explained by nanoporosity alone. It is shown that CO2 saturation and desorption leave a distinct mechanical signature in the glassy matrix before foaming. This matrix contribution provides a new route to understand and optimize the brittle to ductile transition in nanocellular polymers.

Metastable Polymers for Circular 3D Printing
Advanced Materials, EarlyView.3D‐printed polymers are usually permanent and hard to recycle. Here, metastable polymers are designed to fall apart on demand. A chemical trigger unzips the printed material back into its original building blocks within minutes at room temperature.

Preparation and Photocatalytic Performance of PMMA and ZnO/PMMA Nanocomposite films
Journal of Kufa-PhysicsThis study used a simple drop-casting method to create polymethyl methacrylate/zinc oxide (PMMA/ZnO) nanocomposite films. The structural, morphological, and optical properties, and photocatalytic activity of the produced films were studied. X-ray diffraction (XRD) confirmed that pure PMMA is amorphous, while the composite film showed clear peaks for ...
