Embodiment 1

[0055] Steps:

[0056] First place a metal sheet mask with the same size as the polymer substrate and a Φ15mm circular through hole in the center on the polyethylene terephthalate polymer substrate 1 with a size of 50mm×50mm×1mm 2;

[0057] Then, coat a layer of polyurethane 101 strong adhesive glue on the upper surface of the mask;

[0058] Using the vapor phase chemical deposition method, a metal silver coating 3 with a thickness of 2 μm is deposited on the upper surface of the mask plate and the exposed polymer layer in the area of ​​the circular hole indiscriminately (that is, uniform in thickness). The metal silver coating 3 on the upper surface of the mask is bonded to the polyethylene terephthalate polymer 1, and the bonding position is the area to be tested for adhesion, and the metal silver coating on the upper surface of the mask is strongly adhered to the polyurethane 101. Consolidation with the mask under the action of gel glue;

[0059] Apply AMONIL-MMS with a th...

Embodiment 2

[0063] Except that the shape of the through hole is an equilateral triangle (the area of ​​the equilateral triangle is equal to the area of ​​the Φ15mm circular hole), all the others are the same as in Embodiment 1.

[0064] Measurement results: the adhesive force between the metallic silver coating 3 and the polyethylene terephthalate polymer substrate 1 was 87.06N.

Embodiment 3

[0066] Except that the shape of the through hole is a rhombus (the area of ​​the rhombus is equal to the area of ​​a Φ15mm circular hole), all the others are the same as in Embodiment 1.

[0067] Measurement results: the adhesive force between the metallic silver coating 3 and the polyethylene terephthalate polymer substrate 1 was 87.04N.

Abstract

The invention discloses a measuring method for bonding force between a polymeric substrate and a metal coating .The measuring method comprises the steps that on the basis of the prior art, a mask plate with a central through hole is adopted and horizontally placed on the polymeric substrate, and the upper surface of the mask plate is uniformly smeared with a layer of strong bonding glue; the metal coating is deposited on the strong bonding glue, and then when a tensile force testing device exerts tensile force, only interface separation between the portion, under the through hole, of the metal coating and a polymer can be generated at an interface due to the fact that the thickness of the mask plate is larger than that of the metal coating .According to the method, the technical problem that in the prior art, the detected bonding force value between the metal coating and the polymer is actually the resultant force of the true bonding force value between the metal coating and the polymer and the consumption value that the edge of the metal coating is fractured to generate cohesive force is skillfully solved .The measuring result is true and accurate and has the universality.

Description

technical field [0001] The invention relates to a method for measuring the interface bonding force of composite materials, in particular to a method for measuring the bonding force of a metal coating and a polymer, and belongs to the technical field of composite material interface strength detection. Background technique [0002] Metal-polymer bilayer composite structures are widely used in electronic devices, biomedical devices, grating structures, and sensors. [0003] The size of the bonding force between the metal coating and the polymer is directly related to the quality of the structure, which in turn affects the performance of the device. The adhesion is derived from the intermolecular interaction between the metal coating and the polymer interface. Therefore, the detection of the adhesion force between the metal coating and the polymer is very important. [0004] figure 1 It is a flow chart of the measurement method of the prior art. like figure 1 Shown, the met...
