Carbon nanotube film composite structure, transmission electron microscope grid using the same, and method for making the same

A method for making a sample-support for transmission electron microscope, comprising steps of:

• supplying an apparatus;
• and
• placing the apparatus on a support, wherein the support defines at least one through hole, a portion of the apparatus being suspended above the at least one through hole, and the step of supplying the apparatus comprises steps of:
• providing a carbon nanotube film structure and a dispersed solution, wherein the dispersed solution comprises a solvent and at least one functionalized graphene sheet dispersed in the solvent;
• applying the dispersed solution on a surface of the carbon nanotube film structure;
• and
• removing the solvent and thereby locating the at least one functionalized graphene sheet on the carbon nanotube film structure.

A method for making more than one sample-support for transmission electron microscope, comprising steps of:

• supplying an apparatus;
• and
• arranging a plurality of supports spaced from each other on a substrate;
• covering the plurality of supports with the apparatus;
• and
• cutting the apparatus corresponding to the plurality of supports, and thereby forming a plurality of apparatus;
• wherein the step of supplying the apparatus comprises steps of:
• providing a carbon nanotube film structure and a dispersed solution, wherein the dispersed solution comprises a solvent and a plurality of functionalized graphene sheets dispersed in the solvent;
• applying the dispersed solution on a surface of the carbon nanotube film structure;
• and
• removing the solvent and thereby locating the plurality of functionalized graphene sheets on the carbon nanotube film structure.
