▎ 摘　　要

NOVELTY - The film has layers of graphene or derivatives of graphene covered on a surface of a wood slice, where the wood slice is processed by alkali solution, thickness of the wood slice is 100 mnanio meter to 1000 microns, the wood slice is made of needle leaf material. The wood slice is obtained by slicing along the direction vertical to the growth direction of the wood. USE - Wood slice based non-porous TEM carrier net supporting film. ADVANTAGE - The film is environment-friendly, has wide raw material source, simple preparation technique, realizes mass production, clearly characterizing the shape and structure of the sample, improves measured data reliability, and stronger tolerance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a Wood slice based non-porous Transmission electron microscopy (TEM) carrier net supporting film manufacturing method. DESCRIPTION OF DRAWING(S) - The drawing shows a photographic view of a Wood slice based non-porous TEM carrier net supporting film.
