Nanotechnology nanomaterial resistivity
General rule of contact measurement method
1 Scope
This standard specifies the contact measurement method for the resistivity of nanomaterials, including measurement principles, instruments and equipment, measurement conditions, measurement procedures,
Influencing factors, etc.
The static four-probe method (Method A) in this standard is suitable for resistivity measurement of nano-film, nano-paste and nano-powder; dynamic four-probe
Method (B method) and dynamic four-wire two-electrode method (C method) are suitable for the measurement of resistivity of nano powders.

The following documents are indispensable for the application of this document. For dated reference documents, only the dated version applies to this article
Pieces. For undated reference documents, the latest version (including all amendments) is applicable to this document.
GB/T 32269 Terms and definitions of nanotechnology and nanoobjects Nanoparticles, nanofibers and nanosheets
3 Terms and definitions
The following terms and definitions defined in GB/T 32269 apply to this document.
3.1
Nanomaterial
Any material whose external dimension, internal or surface structure is at the nanometer scale.
[GB/T 30544.1-2014, definition 2.4]
3.2
Resistivity
The ratio of the current electric field intensity inside the material to the steady-state current density is the volume resistance per unit volume.
3.3
Staticfourprobemethod
Nano-powder material is pre-pressed and molded, and the four-probe resistivity measuring instrument is used to measure the molded sample. Because there is no continuous pressure, the molding is to be tested
The compacted density of the sample remains static, and the method of measuring the resistivity under the compacted density.
3.4
Dynamic four probe method dynamicfourprobemethod
The nano powder material does not need to be pre-compressed. During the measurement process with a four-probe resistivity measuring instrument, the sample to be tested is compacted due to continuous pressure.
The method of measuring the resistivity of the sample to be tested under different compaction densities.
