GB/T 43251-2023Nanotechnologies—Test method for tensile properties of small size nanostructured thin film (English PDF)

Foreword

This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part 1: Structure and Drafting Rules of Standardization Documents" Drafting.

Introduction

Nanostructured films have multifunctional applications in the fields of electrical conductivity, thermal conductivity, filtration and separation, etc. Tensile properties are a quality control for nanostructured films and core indicators of application development. Accurate characterization and measurement of tensile properties are fundamental to the research, development and application of nanostructured films.

The dimensions (length, width and thickness) of nanostructured films depend on the preparation conditions and application fields. Currently targeting small size nanostructures There is no standard test method for thin films, and existing methods use different test specimens (shape and size) and test methods (fixed and loaded).

Systematic experimental research shows that the selection of test conditions and sample size will significantly affect the quantitative characterization of the mechanical properties of nanostructured films. Book The document focuses on market demand, proposes high-precision, low-cost testing methods, and regulates sample size, sample clamping method, loading rate, etc.
