Abstract(J)	近年、クリーンエネルギーとして水素の利活用が推進されており、水素ガスのバリア技術に対する関心度が高まっている。本稿で紹介する「水素ガスバリア塗料」は塗って乾かすだけで容易に高い水素ガスバリア性を付与することができ、その性能は40℃において0.004mL 25μm/(㎡ day atm)という非常に高い水素バリア性を有している。 Translation
Abstract(E)	In recent years, the utilization of hydrogen as a clean energy source has been promoted, leading to increasing interest in hydrogen gas barrier technologies. This study aimed to develop a coating that can easily impart hydrogen gas barrier properties with just a simple application and drying process. As for the Hydrogen gas barrier materials, composite materials composed of one of natural clay montmorillonite and butenediol vinyl alcohol copolymer（BVOH）as a resin were prepared and subsequently evaluated. As a result, it was found that the hydrogen gas barrier coating exhibits helium gas barrier properties nearly 25,000 times higher than nylon.

About search

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.

If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).

Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.

Example) X AND Y → "X and Y (including)" X OR Z → "X or Z (including)"

If AND and OR searches are mixed, OR search has priority.

Example) X AND Y OR Z → X AND (Y OR Z)

If AND search and multiple OR search are mixed, OR search has priority.

Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.

The number in "()" after each item is the number of data that includes that item.

Search tips

When searching by author name, enter the first and last name separated by a space, such as "Taro Jidosha".
