Self-assembled　poly(aniline-co-pyrrole)　(PACP)　hollow　spheres　were　prepared　via　dilute　polymerization　under　an　unstirred　condition　using　ammonia　as　a　polymerization　medium.　The　morphology　of　the　PACP　copolymers　was　studied　by　choosing　several　important　parameters　such　as　stirring　condition,　comonomer　molar　ratio,　synthetic　media　and　polymerization　time.　The　morphology,　structure　and　properties　of　the　PACP　copolymer　spheres　were　characterized　by　scanning　electron　microscopy,　transmission　electron　microscopy,　FTIR,　wide　angle　X-ray　diffraction,　thermogravimetric　analysis　and　four-probe　technique.　It　was　found　that　the　above-mentioned　polymerization　conditions　had　important　influence　on　the　morphology　of　the　PACP　copolymers.　The　polymerization　parameters　could　be　used　to　guide　the　PACP　copolymer　morphology　from　flower-like　structures　to　hollow　spheres　in　polymerization　process.　Uniform　self-assembled　PACP　copolymer　hollow　spheres　with　outer　diameter　and　shell　thickness　of　610　similar　to　863　nm　and　144　similar　to　162　nm,　respectively,　formed　under　the　optimal　polymerization　conditions　of　an　unstirred　condition,　comonomer　concentration　of　0.05　mol/L　in　ammonia　solution　for　24　h.　Moreover,　the　Ag(I)　ions　adsorbability　of　the　PACP　copolymer　spheres　was　examined.　TEM　and　wide　angle　X-ray　diffraction　results　showed　that　silver　nanoparticles　with　10　similar　to　30　nm　size　were　homogeneously　dispersed　in　the　PACP　copolymer　hollow　spheres　after　adsorption,　indicating　that　the　copolymer　spheres　would　had　reactive　adsorbability　of　Ag(I)　ions.
