basic information
**Part 2: Lecture Summary** **Lecture Purpose** Amorphous vinyl alcohol-based resins and EVOH are functional materials that exhibit gas barrier properties 200,000 to 7,000 times greater than PE. However, understanding both the crystalline and amorphous regions is essential when used in a hydrogen environment under high pressure (70 MPa). In this presentation, we will introduce a general discussion of the factors that govern the molecular void size of gas barrier materials, along with an investigation of hydrogen permeability and molecular motion using solid-state NMR 13C nuclear spin-lattice relaxation time T1C, as well as considerations for polymer alloying to impart flexibility and the associated challenges. **Part 3: Lecture Summary** When materials are exposed to high-pressure hydrogen gas, their strength and lifespan may decrease. This phenomenon is known as hydrogen embrittlement and reduces the safety of containers. To prevent hydrogen embrittlement, evaluation tests under high pressure are essential. In this lecture, we will present specific examples of evaluation methods using high-pressure hydrogen gas from the numerous evaluation techniques our company possesses, including exposure tests, tensile tests, and fatigue tests. Additionally, we will discuss high-pressure testing, which is essential for container evaluation, and the analysis of diffusible hydrogen that affects hydrogen embrittlement.
