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BaCO_3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Ba~(2+)规整取向,通过不同方式引入CO_3~(2-)制备结构稳定的BaCO_3,溶解AAO后,得到(PSS/PAH)_n@BaCO_3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。
We proposed an assembly strategy of BaCO_3 nanocomposites in pores of the AAO@(PSS/PAH)_n,which first orients Ba~(2+),then exposed to various sources of CO_3~(2-)(including the decomposed gas of solid ammonium carbonate,CO_2).Initially,polyelectrolyte molecules were alternately assembled on the inner pore walls of an AAO membrane as porous template,followed by controlled assembly of BaCO_3 in confined space.After dissolution of AAO,the(PSS/PAH)_n@BaCO_3 nanocomposites in the forms of nanotubes and nanorods were respectively obtained.
