英文摘要	We propose a facile method to synthesize Janus nanomaterials by seed interfacial sol-gel process against a polystyrene (PS) hollow sphere using three precursor silanes, (3-aminopropyl) triethoxysilane (APTES), methacryloxy propyl trimethoxyl silane (MPS) and tetraethyl orthosilicate (TEOS). The sol-gel process starts from the exterior surface of the seed sphere. Janus nanomaterials were formed in situ onto the seed sphere surface after a self-organized sol-gel process, which possess 3-methacryloxypropyl- and amine-groups terminated at both sides of the shell. Morphology of the Janus nanomaterials could be tunable from intact shell, nanosheet, porous nanosheet and individual nanoparticles by controlling pH, precursor amount and the fraction of binary emulsifier system. After the removal of PS by dissolution under ultrasonication, Janus nanoparticles were eventually achieved. This method is attractive owing to the easiness to continuously adjust morphology of the Janus nanomaterials. On the other hand, composition of the nanomaterials is also flexibly tunable by using different precursors. What's more, the Janus nanomaterials can derive other Janus ones after selective modification and favorable growth of desired materials onto the corresponding side.
