常见错误

❌ 错误:This substance is electroactive for it can conduct electricity.
✓ 正确:This substance is electroactive because it can undergo electrochemical reactions.

错误在于混淆了电活性与导电性。电活性特指能发生电化学反应,而不仅仅是导电;应使用'because'并强调反应性质。

❌ 错误:The electroactive of the material is high.
✓ 正确:The electroactivity of the material is high.

错误在于将形容词'electroactive'误用作名词。正确形式是使用名词'electroactivity'来描述电活性程度。

近义词辨析

electrically active

'electrically active'更泛指任何电相关活动,可能包括导电或响应电场,而'electroactive'特指能参与电化学反应,更具专业性和精确性。

Electroactive polymers are used in sensors, whereas electrically active materials might just conduct current without reaction.

redox-active

'redox-active'强调物质能进行氧化还原反应,常与电子转移相关;'electroactive'更广泛,包括各种电化学响应,但在某些语境中两者可互换,侧重不同。

Redox-active compounds are key in batteries, but electroactive materials can also include non-redox processes like capacitance.
