Growth of multi-walled carbon nanotubes on Si substrate with Fe3O4/DR film as catalyst precursors

Fe3O4纳米粒子与正离子性的重氮树脂在硅基底的表面形成稳定自组装膜,还原后可通过化学气相沉积(CVD)法在硅基底的表面生长多壁碳纳米管.以聚丙烯酸包裹Fe3O4纳米颗粒能够有效地防止纳米粒子的团聚,并提高组装效率,得到均匀的纳米粒子自组装膜,从而获得在硅基底上均匀分布的多壁碳纳米管.Fe3O4 Nanoparticles produce stable self-assembly film with cationic diazoresin (DR) on silicon surface, after reduction of Fe3O4 the multi-walled carbon nanotubes (MWNTs) were grown on the silicon substrate via chemical vapor deposition (CVD) method. The Fe3O4 nanoparticles capped with polyacrylic acid (PAA) can avoid the aggregation of the nanoparticles effectively as well as improving the efficiency of the self-assembly. As a result the thin films with evenly distributed Fe3O4 nanoparticles and the nanotubes uniformly distributed on Si substrate were obtained.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000235043400015&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701SCI(E)中文核心期刊要目总览(PKU)中国科技核心期刊(ISTIC)中国科学引文数据库(CSCD)102187-190+986
