玻璃钢管与"宏工业"

随着科学技术的发展,人们已经开始实施许多规模宏大、技术先进、系统复杂、改良生态环境、具有标志意义的工程.长江三峡、南水北调、西气东输,都可视为其中代表.有的学者将这些巨大工程命名"宏工业",预测人类即将进入"宏工业时代".     

‘Stuffed’ conducting polymers

Conducting polymers (CP) obtained by oxidative polymerization using iron(III) salts shrink when Fe(II) and the excess counter ions are washed out after polymerization. This phenomenon can be used to incorporate active molecules into the CP matrix via their addition to the wash liquid. In the present work we demonstrate this principle on three different CP's: polypyrrole (PPy), poly-terthiophene (PTTh) and poly(3,4-ethylenedioxy thiophene) (PEDT), using ferrocene as a model molecule to be trapped in the polymer films.
