This is a description of a specialized analysis method for soft materials such as polymer materials, organic materials, organic/inorganic composite materials, biological materials, and thin film samples. A 200KV high-energy transmission sample is used to observe the morphology and shape of soft materials, measure dimensions, analyze the fine structure, defects, and crystal structure inside the material. The method also provides high-angle multi-directional morphology observation, diffraction analysis, and bright/dark field imaging at the same time.

Preparation of specimens

• Specimens size: 3mm in diameter and thinned
• Stability of the specimens: specimens that have been processed by chemical or physical methods and are capable of withstanding electron beam irradiation
• Polymer and organic samples: You must provide relevant stability test reports such as the chemical structure of the material, thermal cracking temperature, melting point, liquid crystal transition temperature, glass transition temperature, etc. to the technician or the professor responsible for the instrument, for preliminary review of the analysis feasibility of test piece under electron microscope
• Biological samples: You must first discuss and explain the fixation method and stability of the test piece with the technician or the professor in charge of the instrument
• Samples and magnetic materials that will decompose and release gas when the test piece is irradiated by electron beams will not be accepted
