MRI: Acquisition of a Nanoprobe Instrumentation Cluster

南密西西比大学(USM)的研究人员将利用纳米探针仪器群，包括原子力显微镜(AFM)和摩擦力显微镜(AFM)的升级和模块化添加，以支持纳米和介观结构材料的集成研究，包括线性/星形嵌段共聚物、离聚体、纳米相分离共混物、聚合物液晶图案化材料、聚合物/粘土纳米复合材料、从水性聚合物分散体系制备的纳米结构薄膜、纳米涂层、自组装有机/无机杂化材料、使用纳米管的导电聚合物混合物、自组装生物聚合物合成类似物、智能表面附着聚合物、图案化聚合物分子筛、基于树枝状大分子的阻隔涂层和分离膜。原子力显微镜将在几纳米的尺度上询问表面，而摩擦压痕仪将在下一个更高的尺度上探测机械性能。与其他方法相结合，结构-性质将跨越跨越纳米到微观到宏观光谱的形态层次进行关联。这些仪器将在由NSF MRSEC、NSF-IGERT、NSF-REU资助的项目中发挥关键作用，以及USM的其他资助研究。学术研究人员和仪器开发商之间已经建立了合作伙伴关系。主要调查人员有一个项目和管理计划，其中包括高级培训、日程安排、未来方向和设施维护。南密西西比大学(USM)的研究人员将利用纳米探针仪器群来支持对精细结构的非均质材料的综合、多学科研究，这些材料包括嵌段共聚物、含离子聚合物、混合物、液晶、纳米复合材料、有机/无机杂化材料、涂层和膜。结合其他表征方法，这些材料的结构和性能将在从分子大小到宏观领域的范围内进行询问和关联。这些仪器将在由NSF MRSEC、NSF-IGERT、NSF-REU资助的项目中发挥关键作用，以及USM在追求复杂、多功能材料方面的其他资助研究。学术研究人员和仪器开发商之间已经建立了合作伙伴关系。首席调查员毛里塔尼亚、Morgan和Nazarenko有一个项目和管理计划，其中包括高级培训、高效调度、未来方向和设施维护。

Researchers at the University of Southern Mississippi (USM) will utilize the nanoprobe instrumentation cluster, comprised of upgrades and modular additions to an atomic force microscope (AFM) and tribodindenter nanomechanical testing system, to support integrated research in nano- and meso-structured materials, including linear/star block copolymers, ionomers, nanophase-separated blends, polymer liquid crystal patterned materials, polymer/clay nanocomposites, nanostructured films from aqueous polymer dispersion blends, nanostructured coatings, self-assembled organic/inorganic hybrids, conductive polymer blends employing carbon nanotubes, self-assembled biopolymer synthetic analogues, smart surface-attached polymers, patterned polymeric molecular sieves, barrier coatings and separation membranes based on dendrimers. AFM will interrogate surfaces on the scale of a few nanometers while the triboindenter will probe mechanical properties on the next higher order of scale. Combined with other methods, structure-properties will be correlated across morphological hierarchies that span the nanoscopic-to-microscopic-to-macroscopic spectrum. The instruments will play critical roles in programs funded by NSF MRSEC, NSF-IGERT, NSF-REU, and other-funded research at USM. Partnership between the academic researchers and instrument developers has been established. The principal investigators have a project and management plan that includes advanced training, scheduling, future direction and facility maintenance. Researchers at the University of Southern Mississippi (USM) will utilize a nanoprobe instrumentation cluster to support integrated, multidisciplinary research in finely-structured heterogeneous materials that include block copolymers, ion-containing polymers, blends, liquid crystals, nanocomposites, organic/inorganic hybrid materials, coatings and membranes. Combined with other characterization methods, the structure and properties of these materials will be interrogated and correlated across scales that range from molecular sizes to the macroscopic realm. The instruments will play critical roles in programs funded by NSF MRSEC, NSF-IGERT, NSF-REU, and other-funded research at USM in the pursuit of sophisticated, multifunctional materials. Partnership between academic researchers and instrument developers has been established. The principal investigator Mauritz, Morgan and Nazarenko have a project and management plan that includes advanced training, efficient scheduling, future direction and facility maintenance.
