Title: Film-grid composite substrate for electron microscopy

Abstract: A film-grid composite substrate for supporting specimens in electron microscopy comprises a specimen-support grid adapted for electron microscopy and an ultrathin film of a mixture of organopolysiloxane-polycarbonate interpolymer and polyphenylene oxide. Regions of a major surface of the film are in contiguous relationship with a major surface of the grid, while other major surface regions of the film span apertures defined by the grid structure.
