Abstract(J)	表面を高分子鎖で精密に化学修飾したコロイド微粒子に、高温下でせん断を印加すると、圧縮または延伸のひずみに応じて可逆的に変色するコロイド結晶エラストマ膜が作製できることを見いだした。また、破断しても再成形が可能なために繰り返しの使用が可能であるため、サステナブルなひずみセンシングデバイスとしての活用が期待できる。 Translation
Abstract(E)	In this study, we successfully prepared the colloidal crystal（CC）elastomer films from monodispersed microparticles surface-modified with polymer chains by hot-pressing and shearing. When the shear strain was applied to these microparticles, vivid Bragg reflection colors emerged due to the formation of well-ordered CC structures. The Bragg reflection color reversibly changed between red and blue upon stretching and releasing. Moreover, such CC elastomer films were reshapable and recyclable multiple times. We believe that our CC elastomer films can be applied as environment-friendly strain sensing devices in diverse industries.

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".
