Before designing the next generation of soft materials, researchers must first understand how they behave during rapidly changing deformation. In a new study, researchers challenged previous assumptions regarding polymer behavior with newly developed laboratory techniques that measure polymer flow at the molecular level. This approach may lead to the design of new biomedical, industrial and environmental applications from polymers that aid in blood clotting to materials that more efficiently extract oil and gas from wells. Understanding the mechanics of how materials molecularly react to changing flows is critical to developing high-quality materials, the researchers said, and defining a framework for interpreting and describing these properties has ...

Polympart: Researchers from the University of Konstanz have successfully generated uniform-shape nanocrystals using direct polymerisation. Researchers have demonstrated a new aqueous polymerisation procedure for generating polymer nanoparticles with a single chain and uniform shape. A team of researchers from the University of Konstanz’s CRC 1214 "Anisotropic Particles as Building Blocks: Tailoring Shape, Interactions and Structures”, which has been funded by the German Research Foundation (DFG) since 2016, has demonstrated a new aqueous polymerisation procedure for generating polymer nanoparticles with a single chain and uniform shape, which, as another difference to previous methods, involves high particle concentrations. A corresponding paper ...

PolymPart: The surface properties of polymer materials usually have to be modified to satisfy their application. Plasma treatment has become one of the techniques which is usually applied to modify the surface properties of polymer materials. PET Polymer The plasma treatment enables an increase of the surface energy of the polymer materials, leading to improvement of the adhesion, and biocompatibility. The polymer surfaces modified at the nanometer scale have high homogeneity; plasma treatment always modifies the surface of just several nanometers, thus the properties of polymer bulk are not affected. However, quantitative irradiations of ultraviolet (UV) emission from the plasma have not been taken into account for the plasma treatments. Among the ...
