U.S. - Sweden Cooperative Research: Direct Measurement of Forces Between Model Cellulose Surfaces

该奖项将支持奥本大学的Ron Neuman博士和两位瑞典研究人员之间的合作研究：表面化学研究所的Per Stenius教授和斯德哥尔摩皇家理工学院物理化学系的Per Martin Claesson教授。该项目的目的是研究采用表面力装置研究模型造纸系统的可行性。特别是，将直接测量模型纤维素表面之间的力，以确定和量化纤维素表面与其他表面之间的基本相互作用，这些表面对制浆和造纸具有内在的兴趣和技术重要性。技术发展将包括通过Langmuir方法在分子光滑的云母基质上制备模型纤维素和木质素表面。Blodgett单层沉积。在访问之前，将进行初步的单层实验，以确保有效的表面力测量结果。斯德哥尔摩表面化学研究所在表面力测量方面的设备和经验补充了首席研究员在造纸、单分子薄膜和Langmuir的表面和胶体化学方面的专业知识。Blodgett单层沉积。该研究结果有望在纸浆和造纸工业中得到重要应用。

This award will support collaborative research between Dr. Ron Neuman, Auburn University, and two Swedish researchers: Professor Per Stenius, Institute for Surface Chemistry, and Professor Per Martin Claesson, Department of Physical Chemistry, The Royal Institute of Technology, Stockholm. The objective of the project is to investigate the feasibility of employing a surface force apparatus for studies of model papermaking systems. In particular, the forces between model cellulose surfaces will be directly measured to identify and quantify the fundamental interactions between cellulose surfaces and other surfaces of intrinsic interest and technological importance to pulping and papermaking. Technique development will include the preparation of model cellulose and lignin surfaces on molecularly smooth mica substrates by the method of Langmuir.Blodgett monolayer deposition. Preliminary monolayer experiments will be initiated prior to the visit to ensure productive surface force measur>ements. The facilities and experience in surface force measurements of the Institute Surface Chemistry in Stockholm complement the expertise of the principal investigator in surface and colloid chemistry of papermaking, monomolecular films, and Langmuir.Blodgett monolayer deposition. The results of this research are expected to have important applications in the pulp and paper industries.
