A Langmuir-Blodgett System with Brewster Angle Microscopy and Surface Potential Sensing for Multifunctional and Advanced Materials

我们需要一个能够执行布鲁斯特角度显微镜（BAM）和表面电位传感（SPS）的Langmuir-Blodgett沉积槽。这项技术将使我们能够组装和表征精确控制的薄膜，在多功能和先进材料的加工中具有广泛的应用。BAM提供了关于组装膜的均匀性、相行为和形态的信息，而SPS允许我们控制膜的质量及其在各种衬底上的转移。这是一个最先进的系统，将使我们的实验室和其他实验室能够通过将碳纳米管、纤维素纳米晶体、石墨烯甚至噬菌体等纳米材料组装成结构薄膜，进行多功能先进材料开发的前沿研究。该技术的主要优点是，组装好的薄膜可以以精确控制的排列方式转移到各种各样的衬底上，并且能够在层数和均匀性上进行良好的控制，从而制备多层结构。这些薄膜在先进能源材料、光学和光电子、先进纳米复合材料、生物传感和生物医学工程等新兴领域都有应用。环境室和主动隔振系统将保护样品并提高测量质量。在我们的实验室中，这项技术与其他现有材料表征工具的存在将确保为至少36名研究学员和其他人提供独特的培训环境。资助LB-BAM-SPS系统是一种相对廉价的方式，可以为加拿大研究界带来最先进的设备，为组装纳米结构和薄膜制造领域的创新提供新的机会。

We are requesting a Langmuir-Blodgett Deposition Trough with the capability to perform Brewster Angle Microscopy (BAM) and Surface Potential Sensing (SPS). This technology will allow us to assemble and characterize precisely controlled thin films with a wide variety of applications in the processing of multifunctional and advanced materials. BAM provides information on the homogeneity, phase behaviour and morphology of the assembled films whereas SPS allows us to control the quality of the film and of its transfer onto variety of substrates. This is a state-of-the art system that will allow our laboratories and others to produce cutting edge research on the development of multifunctional advanced materials by assembly of nanomaterials such as carbon nanotubes, cellulose nanocrystals, graphene and even bacteriophage into structured thin films. The major advantage of this technique is that assembled films can be transferred to a wide variety of substrates in precisely controlled aligned arrangement with the ability of preparing multilayered structures with an excellent control on layer numbers and homogeneity. These films have applications in emerging areas such as advanced energy materials, optics and optoelectronics, advanced nanocomposites, biosensing and biomedical engineering. The inclusion of an environmental chamber and active vibration isolation system will protect the samples and improve the quality of the measurements. The presence of this technology with other existing materials characterisation tools in our laboratories will ensure a unique training environment for at least 36 of our research trainees and others. Funding of the LB-BAM-SPS system would be a relatively inexpensive means to bring state-of-the art equipment to the Canadian research community, providing new opportunities for innovation in the fields of assembled nanostructures and thin film fabrication.
