利用響應性聚合物聚（乙二醇-b-N-異丙基丙烯酰胺）（PEG114-b-PNIPAm130）和聚（N異丙基丙烯酰胺b4乙烯基吡啶）（PNIPAm106bP4VP102）在水溶液中自組裝形成核-殼型復合膠束，并以其為單一軟模版，以四甲氧基硅烷（TMOS）為前軀體，溫和條件下，一步法制備得到了形態、尺寸可控的介孔空心硅球。這種介孔空心硅球具有大的比表面積（1 01811 m2/g）和介孔尺寸（121 nm）。研究了交聯劑、灼燒及不同pH值對所得空心硅球形態、尺寸等的影響。最后以牛血清蛋白為模型蛋白，研究了介孔硅球對大分子的吸附能力。

Controllable largepore mesoporous hollow silica nanospheres (LMHSN) with large surface area (1 01811 m2/g) 〖JP+1〗and mesoporous width (121 nm) was synthesized through a general method. Firstly, responsive block copolymers poly (ethylene glycolbNisopropyl acrylamide) (PEG114bPNIPAm130) and poly (Nisopropyl acrylamideb4vinyl pyridine) (PNIPAm106bP4VP102) selfassembled into coreshell complex micelles, followed by silicification of the shell with the addition of the silica precursor tetramethoxysilane (TMOS) under mild condition. Then, the effects of addition of crosslinker and different pH values on the structure and morphology of LMHSN were discussed. Finally, we studied the ability of the adsorption of macromeolecular by the LMHSN.
