Particle size distribution of Cu nanoparticles in polyimide film
In the past, for metal or ceramics nanoparticles dispersed in a film, the average particle size and distribution were estimated from cross-sectional transmission electron microscope (TEM) images, which required enormous labor and time.
Small angle X-ray scattering (SAXS) measurements can be made in tens of minutes using a sample of about 15 mm × 2 mm, with no need to slice or pre-treat the film.
The images below show the temperatures of heat treatment and cross-sectional TEM photos of samples in which copper nanoparticles were dispersed in the polyimide film.
The graphs below show the SAXS data (top) and the the results of analysis with NANO-Solver (bottom); the average particle sizes were determined to be 3.9 nm and 8.8 nm.

The S-MAX3000 pinhole SAXS camera design is available with a choice of conventional or high brilliance X-ray sources. A 3-meter, fully evacuated camera length provides both high intensity and high resolution. Coupled with a fully integrated 2-dimensional multi-wire proportional counter, the system is capable of making highly sensitive measurements from both isotropic and anisotropic materials. A wide range of sample stage attachments provide maximum flexibility in controlling environmental sample conditions during measurement. Read more...
