我们实现了使用几种有机聚合物整体作为孔模板的共连续二氧化钛基整体材料的制备。首先，制备了结构可控的有机聚合物整体材料，并用钛酸四丁酯（钛单体）填充聚合物整体材料的孔。钛单体的以下水解产生二氧化钛。通过在升高的温度下煅烧除去聚合物整料。我们仔细研究了聚合物整体模板剂的使用，钛单体的填充方法，以及煅烧条件，以实现双连续二氧化钛整体。此外，通过改变模板的晶畴尺寸（骨架尺寸+通孔尺寸），我们能够控制所得二氧化钛整料的晶畴尺寸。
We achieved preparation of co-continuous titania based monolithic materials using several organic polymer monoliths as pore templates. Firstly, the organic polymer monoliths that had well controlled structures were prepared, and filled the pores of polymer monolith with tetra-n-butyl titanate (titan monomer). The following hydrolysis of the titan monomer resulted in titanium dioxide. The polymer monolith was removed by calcination at elevated temperature. We carefully studied the utility of polymer monolithic template, filling method of the titan monomer, and calcination conditions to realize co-continuous titania monolith. In addition, by the change of domain size (size of a skeleton+size of through a pore) of template, we were able to control domain size of the resulting titania monoliths.
