油纸伞是中国具有千年历史的传统手工艺品，也是中国传统文化的重要象征。本文以一位老工匠为即将出嫁的女儿制作油纸伞作为嫁妆的故事为背景，深入探讨油纸伞制作过程中蕴含的化学原理，包括碱法制浆、柿漆粘结、朱砂附着和桐油防水等关键工艺。同时，本文挖掘其背后的思政元素，将文化、化学与思政教育有机结合，实现知识传授与价值引领的统一。

A low-cost 1D cobalt-based coordination polymer (CP) [Co(BGPD)(DMSO)₂(H₂O)₂] (Co-BD; H₂BGPD=N, N'-bis(glycinyl)pyromellitic diimide; DMSO=dimethyl sulfoxide) was synthesized by a simple method, and its crystal structure was characterized. In a three-electrode system, Co-BD, as the electrode material for supercapacitors, achieved a specific capacitance of 830 F·g^-1 at 1 A·g^-1, equivalent to a specific capacity of 116.4 mAh·g^-1, and exhibited high-rate capability, reaching 212 F·g^-1 at 20 A·g^-1. Impressively, Co-BD||rGO (reduced graphene oxide), representing an asymmetrical supercapacitor, owns a higher energy density of 14.2 Wh·kg^-1 at 0.80 kW·kg^-1, and an excellent cycle performance (After 4 000 cycles at 1 A·g^-1, the capacitance retention was up to 94%).
