【摘要】 利用空间限域作用可控制晶体生长过程、优化晶型和结构稳定性[1-2]。加入聚电解质可调控晶体预成核和生长[3]。因此,本文提出了一个在聚电解质限域空间中组装BaCO₃的策略。以阳极氧化铝（anodized aluminum oxide,AAO）为模板,层层组装聚烯丙基氯化铵（poly-allylamine hydrochloride,PAH）和聚苯乙烯磺酸钠（poly-sodium 4-styrene-sulfonate,PSS）得到AAO@（PSS/PAH）_n,有序排列的PSS使吸附的Ba²⁺规整取向,通过不同方式引入CO₃^2-制备结构稳定的BaCO₃,溶解AAO后,得到（PSS/PAH）_n@BaCO₃纳米管和纳米棒。本工作在可控组装和催化领域具有应用前景。更多还原

【Abstract】 We proposed an assembly strategy of BaCO₃ nanocomposites in pores of the AAO@（PSS/PAH）_n,which first orients Ba²⁺,then exposed to various sources of CO₃^2-（including the decomposed gas of solid ammonium carbonate,CO₂）.Initially,polyelectrolyte molecules were alternately assembled on the inner pore walls of an AAO membrane as porous template,followed by controlled assembly of BaCO₃ in confined space.After dissolution of AAO,the（PSS/PAH）_n@BaCO₃ nanocomposites in the forms of nanotubes and nanorods were respectively obtained.更多还原
