を調製することを試みた。その結果、最大でTRIM の含有率が約40 %のMCを調製できた。さらにこのMCを3 wt%（w/w）の割合で混合したエポキシ樹脂を作製し、その材料の自己修復能力を評価した。その結果、樹脂に約32%の自己修復能力を付与できた。","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"科学・技術研究会"},{"subitem_publisher":"Studies
