cationic

Cationic是英語中的形容詞，意為“陽離子的”，用於描述攜帶正電荷的離子特性，其反義詞為“anionic”（陰離子的）。該術語源於19世紀麥可·法拉第在電解實驗中對離子遷移現象的發現，並隨著現代化學發展逐漸成為化學領域的基礎辭彙，常見於電解質、膠體化學等學科。

在套用層面，cationic被廣泛用於描述高分子材料、表面活性劑等物質的帶電特性，衍生出如cationic surfactant（陽離子表面活性劑）、cationic polymerization（陽離子催化聚合作用）等專業術語。其在染料廢水脫色、聚合物製備、醫學材料（如陽離子脂質體）及環境工程等領域均有實際套用。此外，該詞通過詞根“cation”形成術語體系，包括cationic detergent（陽離子洗滌劑）、cationic collector（陽離子收集極）等，體現了其在跨學科中的通用性。
