New Phosphate Glass Polymer Hybrids Current Status and Future Prospect
Multiphase polymeric materials like polymer blends and composites are crucial in meeting global material needs. These materials’ ability to be tailored for specific applications has driven significant growth in the polymer blend industry. However, conventional polymer blends can’t fulfill all new technological needs. This gap is being bridged by inorganic/organic hybrid materials, offering improved, tunable properties. Notably, phosphate glass/polymer hybrids, created by blending low-temperature inorganic phosphate glass with organic polymers, exhibit enhanced properties without the disadvantages of traditional filled plastics, presenting new opportunities for advanced material development.

Stabilization of Hot-Melt Extrusion Formulations Containing Solid Solutions Using Polymer Blends
In this study, researchers worked on improving the stability of a medication called clotrimazole, commonly used in treating fungal infections. They used a technique called hot-melt extrusion, blending two types of polymers – hydroxypropyl cellulose and poly(ethylene oxide) – to create films that carry the drug. The films were thoroughly tested for their physical and chemical properties, including how they absorb moisture, stick to biological surfaces, and how flexible they are. The goal was to find the perfect mix that ensures the drug is released effectively, remains stable, and has good adhesive qualities. This research is a significant step towards developing better drug delivery systems, enhancing both the effectiveness and user experience of the medication.

Modeling of magnetic properties of polymer bonded Nd–Fe–B magnets with surface modifications
In this breakthrough led by Jun Xiao, Joshua U Otaigbe, and David C Jiles, researchers explored the transformative effects of coating magnetic powders with an organometallic compound on the performance of polymer-bonded Nd–Fe–B magnets. These magnets, blending polymer matrices and magnetic powders, offer cost-effective advantages and unique shaping possibilities compared to metallic or ceramic counterparts.
The study revealed that the coating significantly enhanced the magnets’ irreversible loss in flux and energy product, providing a protective shield against moisture and oxygen, particularly at high temperatures. Using a theoretical model based on energy balance during domain magnetization, researchers deciphered changes in magnetic properties, indicating that the coating treatment increased the remanence of polymer-bonded magnets by fostering better interaction among magnetic particles.

New Protective Coatings for Rare Earth Magnets Prevent their Corrosion and Oxidation
Commercial rare-earth alloy powders such as neodymium-iron-boron (Nd-Fe-B) or “neo alloy” ribbons into platelets with varying sizes and distributions (mean particle size approximately 200 µrn). The neo alloy powders produced by this method are highly sensitive to moisture and oxidize readily in air. The spherical neo alloy powders (mean particle size approximately 40 µm) made by high-pressure gas atomization are even more sensitive to fluctuations in the moisture and temperature.
When heated in air at high temperatures, the reactivity of the gas-atomized powder increases, which may be due to its higher specific surface area. The thermal oxidation of neo alloy powders is due to their direct oxidation in air and is exacerbated in the presence of an aqueous electrolyte. In general, oxidation rates are low at air temperatures below 150°C. However, very high oxidation rates can be produced in humid environments. The rapid attack occurs via the preferential consumption of Nd- and B-rich phases on the grain boundaries, which causes the grains of the ferromagnetic phase to loosen. This, in turn, diminishes the structural integrity of the magnet.

Controlling the Water Absorbency of Agricultural Polymers
Blending special bioabsorbable polyphosphate fillers, biodegradable soy protein isolate, plasticizer, and adhesion promoter in a high-shear mixer followed by compression molding resulted in a relatively water-resistant, biodegradable soy-protein polymer composite.
Natural biodegradable polymers made from agricultural products, such as soy protein isolate and corn starch, have poorer water resistance than synthetic polymers derived from petrochemicals and thus absorb more moisture. As a result, commercial exploitation of agriculturally derived materials has been very limited. The targeted applications for the natural biodegradable polymers require that the materials have sufficient stiffness and strength during their useful life but eventually biodegrade. Achieving this required combination of properties from the biodegradable polymers is very difficult because of their inherent water sensitivity and relatively low stiffness and strength, especially in moist environments. To address these problems, the author recently initiated a long-range research project to develop affordable, stiff, strong bioabsorbable polyphosphate filler/soy protein polymer composites, along with methods for making practical shapes from these products· The research involves blending special bioabsorbable polyphosphate reinforcing fillers having low glass transition temperatures and the biodegradable soy-protein polymer using a single-screw (or twin-screw) extruder at temperatures above the polymer’s melting point. The blended soy-protein polymer composite containing the required amount of the reinforcing fillers is then either injection molded or compression molded into articles of various shapes and sizes.

The difficulties of mass-producing micron-sized high-quality powders from molten polymers can be avoided by using high pressure gas atomisation methods.
The production of micron-sized polymer powders from molten polymers is an attractive, facile, low energy, and economic process. Polymer powders with tailored characteristics such as particle shape and size distribution, and purity can be directly prepared from the molten state of polymers such as polyethylene-based waxes that cannot be ground using conventional grinding methods. The gas atomisation process (GAP) for mass-producing high quality spherical polymer powders involves the use of high pressure (approximately 7.6MNm-2 maximum) nitrogen gas and a specifically designed nozzle to atomise a molten stream of polymer into fine droplets which cool to form spherical powders, Powders with properties tailored to varying applications can be efficiently produced in short cycle times by changing few process control variables in a contamination-free environment, thus making the GAP a useful alternative to conventional grinding processes. These benefits of the process together with its flexibility, high throughput and facile nature can be expected to make it highly attractive to industrial processes that must be capable of mass production, safe and environmentally benign operation.
