SPM Observation of Physical Property Distribution in Ultra-Small Regions of Resin Film

User Benefits

- The distribution of physical properties (adsorption force, sample deformation, elastic modulus, etc.) in an ultra-small region can be measured. - Targets can be evaluated under atmospheres close to the actual use environment (air, inert gas, low vacuum, etc.). - The high performance optical microscope integrated into the SPM enables precise target location.

Introduction

Resins are widely used in various fields such as packaging materials, industrial parts, and paints due to their diverse characteristics such as durability, transparency, gas barrier properties, and ease of processing. Because of their versatility, resin products are required to have a wide range of functions, and even today the development of such products is being pursued from various perspectives. In the development of new materials, multiple types of resins are often mixed to obtain new characteristics, and checking the mixture state is an important process for the development. However, when the dispersion is on the order of nanometers, it is not easy to evaluate the state of the dispersion. The scanning probe microscope [SPM (AFM)] is a microscope that can measure the 3D topography and distribution of physical properties of a sample surface on the nanometer order. In this article, we introduce an example of measuring the dispersed state of the constituent resins in a resin film produced by mixing several different types of resins, using the high-speed property mapping of SPM.
