    • 摘要: 水滑石等二维层状材料的功能化和自组装对纳米材料的广泛应用至关重要.本文利用LB技术制备了磺酸基团离子交换后的水滑石和两种不同结构染料的自组装Langmuir薄膜.探究了染料复合LB薄膜表面的聚集状态及膜的结构/性能.采用原子力显微镜和透射电镜对单层Langmuir膜的形貌进行了表征,结果表明薄膜具有较好的均匀性和致密性.利用紫外-可见光谱对制备的磺酸基团水滑石/染料LB膜的良好酸致变色特性进行了研究.本文的研究工作为水滑石界面有效功能自组装薄膜的制备和发展以及酸碱气体传感器、化学开关等实际应用提供了新的线索.

    • 摘要: 设计合成了胆固醇修饰的环糊精衍生物(CD—CHOL)以及偶氮苯修饰的聚丙烯酸化合物(PAA—Azo),通过气液界面组装成功制备了Langmuir膜,由表面压-分子面积等温线表征界面铺展行为,采用原子力显微镜(AFM)对单层Langmuir膜的形貌进行了表征,进一步通过紫外光谱、圆二色谱、红外光谱、X射线光电子能谱研究组装膜中环糊精与偶氮苯基团的自组装过程与主客体识别机理.实验结果表明,CD—CHOL在纯水亚相与PAA—Azo亚相表面形成稳定的Langmuir膜,同时环糊精与偶氮苯基团之间发生了主客体识别.本研究工作为环糊精衍生物界面组装与主客体识别相关研究提供了新的探索.%Cholesterol-modified beta-cyclodextrin derivative (abbreviated as CD-CHOL) and the azobenzene-modified poly(acrylic acid) compound (abbreviated as PAA-Azo) have been designed and synthesized.And the Langmuir films have been successfully prepared by the interfacial self-assembly, which could be verified by the surface pressure-area isotherms.Atomic force microscopy was utilized to characterize the morphologies of Langmuir films.In addition,the process of self-assembly and host-guest recognition between cyclodextrin and azobenzene segments have been investigated by various methods, including UV-Vis,CD,FT-IR,and XPS spectra.The experimental data indicated that the CD-CHOL Langmuir films could be prepared stably both on pure water subphase and PAA-Azo subphase.At the same time, the molecules recognition occurred between cyclodextrin and azobenzene groups.The present research work would provide beneficial exploration for the research of interfacial self-assembly and host-guest recognition of cyclodextrin derivatives.

    • 摘要: With the development of nanotechnology and the application of nanomaterials, different kinds of nanocomposite films should be prepared. In this review, nanoarchitectonics involving films preparation, nano-level material interactions, synergistic effect of external stimuli, and later research progress are summarized. There are three main methods for the preparation of self-assembled thin films:self-assembled monolayer ( SAM) technique, layer-by-layer ( LbL) assembly and Langmuir-Blodgett ( LB) method. Surface nanostructures are prepared effectively and accurately by SAM technology. LbL assembly and LB techniques both provide effective methods for preparing controlled layered nanoarchitectures. Generally, LbL assembly method is commonly used in the preparation of a large area of layered nanostructures. On the other hand, LB technology is mainly used in the preparation process of the unique dynamic interface to achieve the preparation of ultra-thin film.%随着纳米技术的进步,为实现纳米材料各种应用功能,需要制备不同的纳米组装薄膜材料.本文对纳米组装薄膜制备、薄膜制备过程中分子间相互作用、外界刺激下协同作用以及未来发展方向进行了详细综述.在膜纳米结构中,制备薄膜主要有3种方法:自组装单分子膜(SAM)、层层自组装(LbL)以及LB膜技术.SAM技术能够有效、精确地制备表面纳米结构.层层自组装技术及LB技术能够有效地控制并制备层状纳米结构.层层组装方法常用于制备面积较大的层状纳米结构;LB技术主要是利用其制备过程中独特的动态界面实现对超薄膜的制备.

    • 摘要: Diethylaminoethyl(DEAE)-Agarose was studied for preparing monolayers based on the Langmuir-Blodgett(LB) film tech-nology .A high collapse pressure and a standard film forming process were found in the surface pressure (π)-area ( A) isotherm of DE-AE-Agarose.The effect of DEAE-Agarose concentration on the film formation showed that 0.5 mg/mL was the best .The surface poten-tial increased with rise of the ligand density .DEAE-Agarose LB films were characterized with Brewster angle microscopy ( BAM) and atomic force microscope ( AFM) after being transferred onto silicon surface .The morphology of the film was pretty compact , well struc-tured, and relatively smooth.The thickness was about 7.9 nm and the roughness was about 2 nm.This result indicated that the DEAE-Agarose LB film was successfully prepared and could be an novel material for the fabrication of LB films .%由于单分子膜性能独特,受到关注度越来越高,利用LB膜技术制备了二乙氨乙基( DEAE)-琼脂糖单分子层。分析其表面压(π)-面积( A)曲线,崩溃压较高,成膜过程明显。研究浓度对DEAE-琼脂糖成膜情况的影响,确定最佳成膜浓度为0.5 mg/mL。考察配基密度与表面电势的关系,其表面电势随着配基密度的增加而增大。采用原子力显微镜(AFM)和布鲁斯特角显微镜(BAM)对制备的LB膜进行了表征,得出表面膜的表面平整、紧密,厚度约为7.9 nm。 DEAE-琼脂糖LB膜制备成功,为以后LB膜技术的广泛应用提供了一种新的材料。

    • 摘要: 在草酸钙过饱和溶液中,利用十八胺和硬脂酸Langmuir-Blodgett(LB)多层膜为模板,文章研究了草酸钙(CaOxa)在LB膜上的结晶行为,采用X射线衍射(XRD)和金相显微镜等技术对CaOxa晶体的结构和形貌进行了表征.实验结果表明,在中性溶液中可以形成一水草酸钙(CaC2O4·H2O,COM)和二水草酸钙(CaC2O4·2H2O,COD)混合晶体,而在同样条件下,十八胺LB膜上只形成COD晶体.

    • 摘要: LB膜(Langmuir-Blodgett Film)是以其实验技术奠基人艾尔文·朗缪尔(Irving Langmuir)和凯瑟琳·布洛杰特(Katherine Blodgett)姓氏命名,在液体或固体基底上制备的单分子层或少分子层(通常是有机分子)薄膜的总称.LB膜是一种有序组装薄膜,通常利用表面活性剂类分子的头基与尾基亲疏水性相异的特性,在液相(水相或油相)界面上,通过控制膜层表面积的方式使分子形成有序排列,再以浸没法等方法实现膜层向其他基底的的转移.LB膜因其独特的物理、化学与生物性质及其可控的结构和性能在诸多领域有着广泛应用,例如:纳米尺度电子器件、自组装光电转换材料、生物兼容性分子膜等等.LB膜分析仪是集膜压测量与控制、温度和电势测量与控制、膜层基底转移与数量控制等于一身的多功能分析制备仪器.本文以KN2002型LB膜分析仪为例,主要论述其结构与主要功能,重点就使用与维护过程展开论述.
