Abstract

The invention belongs to the field of composite materials and in particular relates to a laminated metal chalcogenide (LMC) / carbon nanotube (CTNs) flexible compound film material of a highly ordered structure and a preparation method thereof. The composite material comprises an ultrathin self-supporting (transparent) CNTs film substrate and an LMC film which uniformly wraps the surface thereof to form the flexible composite film material which has a nanoscale porous structure and a three-dimensional network structure of a high electric channel. The preparation method comprises the following steps: providing an alloy bracket for bearing a self-supporting CNTs film and cleaning the carried CNTs film under a heating condition with plasma; and preparing the LMC / CNTs composite functional film material from the pre-treated CNTs film at an air pressure of 0.2-2Pa and at a temperature of 30-800 DEG C by virtue of a magnetron sputtered deposition technology. According to the material provided by the invention, a crispy laminated metal chalcogenide functional two-dimensional (2D) material and one-dimensional (1D) CNTs are effectively connected to form a three-dimensional (3D) network structure of structural flexibility.

Description

technical field

[0001] The invention belongs to the field of composite materials, and in particular relates to the structural design and preparation method of a layered metal chalcogenide (LMC) and carbon nanotube (CNTs) flexible composite film material with a highly ordered structure. Background technique

[0002] In recent years, as the imbalance between energy supply and economic development has become prominent, the energy crisis and environmental pollution have become increasingly serious worldwide. "Energy saving and carbon reduction" and the search for clean energy technologies are issues of concern to all countries today. Thermoelectric materials are advanced functional semiconductor materials that can convert heat and electricity, which are two different forms of energy, and can make full use of waste heat and waste heat in daily production and life to generate electricity. Important research content in the environmental science and technology project. When the siz...
