A TEM sample preparation method based on cryoultramicrotomy, adapted for extremely low-modulus (1 MPa) elastomers, was developed, allowing the gold nanoparticles in a PDMS matrix to be imaged. The cluster size, size distribution and implantation depth of 50 nm were determined from the images and used to calculate the Young’s modulus of the implanted layer.Metal ion implantationEAPPDMSElasticity ofnanocompositesGold clusterstext::journal::journal article::research article
