Researchers Developed Sustainable Nanocomposite Films
A new bio-based film blend integrates silver nanoparticles and reduced graphene oxide to improve material properties.
Updated on Sept. 24, 2026 in Materials Science
Scientists have created a new class of bio-based nanocomposite films using a ternary blend of poly(vinyl alcohol), poly(vinyl pyrrolidone), and carboxymethyl cellulose. These films incorporate silver nanoparticles and reduced graphene oxide nanosheets to enhance structural and thermal performance.
Why it matters
The study proposes this ternary matrix as a foundational platform for developing future sustainable, lightweight nanocomposite materials. This approach leverages biodegradable components to create high-performance films suitable for a variety of advanced applications.
The films feature silver nanoparticles with an average crystallite size of 24.82 nm and a specific surface area of 22.92 m/g. Thermal stability is highlighted by a glass transition temperature that rose from 72.1 °C to 88.8 °C with the addition of fillers.
The details
The nanocomposites were produced through a solution casting technique and analyzed using XRD, FTIR, SEM, and EDX methods. The films demonstrated ortho-positronium lifetimes between 1.452 and 1.530 ns, with free-volume sizes ranging from 52.04 to 59.51 ų.
