| 英文摘要 | 构建磁性薄膜,在磁性理论和应用技术上都有重要意义[1].通过磁性膜的研究,能揭示磁性机制,对界面磁性、维度磁性、磁性的藕合特征、磁性量子效应等建立新的认识.磁性膜还提供一种新的人造磁性材料,在信息储存[2]、磁性图像[3]、医学[4]等方面有潜在应用.目前,形成磁性薄膜的技术主要有溅射(Sputtering)[5]、分子外延性生长(Molecular beam epitaxy)[6]、真空喷镀[7]、电泳、脉冲激光沉积、Langmuir-Blodgett(LB)沉积[8,9]、层层组装(LBL)[10-16]等方法.; Magnetic ultrathin films were fabricated layer-by-layer using a self-assembly method through the electrostatic interaction between the photosensitive diazoresin (DR) and the negatively charged Fe(3)O(4) nanoparticles (NP-Fe(3)O(4)). The results of the UV-vis spectra and AFM show that the assembly of DR and NP-Fe(3)O(4) is very successful. After UV irradiation, the ionic bonds of the DR/NP-Fe(3)O(4) film convert to covalent ones and the magnetic films become very stable toward polar solvents. The magnetic film images with good resolution are obtained by means of selective UV-exposure of the film under a photo-mask and then developing the exposed film in the saturated aqueous solution of sodium dodecyl sulfate (SDS) and cetyl trimethyl ammonium bromide (CTAB), respectively.; 国家自然科学基金; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000222256700030&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(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); 2; 3; 458-461 |
