US-Egypt Cooperative Research: New Coating Formulations Containing Natural Inhibitors for Steel Corrosion Control

说明：该奖项旨在支持阿拉巴马州塔斯基吉大学地质化学系的Adriane Ludwick博士和埃及亚历山大大学化学系的Esam Ibrahim Al-Hanash博士之间的合作研究项目。研究人员将研究新的抗腐蚀聚合物配方，并从中东地区的本土草药和/或海水中的绿藻中提取提取物。钢结构的表面处理将被检查。将通过交流阻抗和盐雾试验等实验室加速试验，以及通过在埃及亚历山大港浸泡样品进行实地研究，对含有天然提取物的聚合物涂层进行性能评估。这项工作是基于塔斯基吉大学和亚历山大大学之前的成功合作，其中使用从藻类中提取的化合物开发了一种防腐涂层。这种合作的成果目前正在埃及通过最终用户参加的讲习班进行传播。适用范围：含防腐添加剂的有机聚合物作为涂层材料，用于增强土建、地埋管道、海洋构筑物等钢结构的防腐能力。这些涂层可用于复杂形状的截面，如弯头、阀门和三通截面。该项目将受益于两所私立大学的互补技能，以及两所大学之间目前建立的良好联系。美国PI在该领域有经验，他们开发了一种含有藻类的清漆，这种清漆在海洋环境中被证明是有效的。该项目的结果将由两位科学家向最终用户传播。年轻教师参与拟议的项目将增强未来国际合作的潜力。该项目将向学生介绍腐蚀速率和机制的电化学评估的现代技术，以及抑制钢腐蚀的天然有机手段的类型。该项目得到了美国-埃及联合基金项目的支持，该项目向两国的科学家和工程师提供赠款，以开展这些合作活动。

0317586LudwickDescription: This award is to support a cooperative research project between Dr. Adriane Ludwick, Chemistry Department of Geology, Tuskegee University, Tuskegee, Alabama and Dr. Esam Ibrahim Al-Hanash, Chemistry Department, Alexandria University, Alexandria, Egypt. The investigators will study new anti-corrosion formulation of polymer together with extracts from herbs indigenous to the Middle East area and/or green algae available in seawater. Surface treatment of steel structures will be examined. The performance evaluation of the polymer coatings containing the natural extracts will be done by means of laboratory accelerated tests such as ac impedance and salt spray fog test, as well as by means of field studies through immersion of samples in the Alexandria Harbor of Egypt. This work is based on a previous successful collaboration between Tuskegee University and Alexandria University in which an anti-corrosion coating was developed using compounds extracted from algae. The results of that collaboration are currently being disseminated through workshops in Egypt attended by the end-users. Scope: Organic polymers with anti-corrosion additives are used as coating materials to enhance the corrosion protection of steel structures such as civil engineering constructions, buried pipelines and marine structures. These coatings can be used in complex shaped sections such as bends, valves and tee sections. The project will benefit from the complementary skills of the two PIs, and from the currently well-established links between their universities. The U.S. PI has experience in the field having developed a varnish containing algae that has proved effective in marine environments. The results from this project will be disseminated by the two scientists to end-users. The involvement of younger faculty in the proposed project will enhance the potential for future international collaborations. The project will introduce students to modern techniques of electrochemical evaluation of corrosion rates and mechanisms, and to the types of naturally occurring organic means for inhibiting corrosion of steel. This project is being supported under the US-Egypt Joint Fund Program, which provides grants to scientists and engineers in both countries to carry out these cooperative activities.
