Researchers developed isosorbide-based plasticizers that made brittle poly(isosorbide carbonate) more flexible while preserving its ability to undergo ammonolysis after use. The resulting degradation products supported plant growth, including in an edible vegetable, highlighting a new way to design plastics with a useful end-of-life function.
A new type of plastic that turns into a gas when heated and reforms into a solid when cooled has been developed by scientists at the University of Surrey, opening up a new approach to processing and recycling polymers.
Virginia Tech chemist and chemical engineer Guoliang “Greg” Liu and his lab have developed a process that converts the plastic polyvinyl chloride (PVC) into polyalphaolefin, a key component in lubricants such as engine oil.
The review compares phase inversion, film stretching, melt extrusion, sacrificial templating, and electrospinning as routes to PFAS-free waterproof breathable membranes. It finds that no single method maximizes waterproofness, breathability, durability, and scalability, highlighting the need for application-specific design and standardized testing.
Researchers showed that strong metal-polymer bonding depends on electron donation from polymer functional groups into vacant orbitals on oxidized metal surfaces. By engineering oxygen vacancies and carboxyl groups, they increased the tensile-shear strength of magnesium alloy/CFRTP joints by more than 400%.
Researchers embedded a sulfonate-functionalized covalent organic framework in a fluorinated polymer electrolyte, creating ordered pathways that increased sodium-ion conductivity to 1.2 mS cm?¹ at 30 °C. The composite supported long-lived sodium-metal cycling and retained 87.3% capacity after 488 cycles in a 1 Ah solid-state pouch cell.
Master Bond UV16Med-FD is a one part, low viscosity, epoxy based UV curable system containing a fluorescent dye for identification.
Researchers have developed a new 3D printing technique that allows the printing of whole objects and controls the temperature of the chemical reaction to stabilize the process.
The review finds that biodegradable plastics could help reduce persistent plastic pollution, but only if paired with lower plastic use, better recycling, clear certification, and proper disposal infrastructure. It highlights major barriers, including high costs, inconsistent real-world degradation, environmental trade-offs, and limited waste-management systems.
Researchers at the U.S. Department of Energy’s (DOE) Oak Ridge National Laboratory (ORNL) have created a new tool that can catch and correct potential mistakes in real time while 3D printing large plastic parts.
