Various types of materials can be included in LbL films. In this study, polyelectrolytes were chosen to assemble LbL films. They contain charge groups in their repeat units that dissociate in aqueous solutions. Both polycation and polyanion interact with each other through electrostatic forces. This type of directed self-assembly can be used to build up multi-material films at the nanoscale. Polyelectrolyte multilayer films are of interest for a number of properties, including anti-icing. Ice formation has been a big problem for society in many industries such as transportation, agriculture and aviation. Currently, anti-icing methods which are used are costly and inconvenient. In this work, a passive and facile anti-icing technique based on lubricant-infused porous polyelectrolyte multilayers is presented. They are shown to delay ice nucleation and formation. Also, the coalescence of condensed drops on both superhydrophobic and lubricated surfaces are compared and analyzed. We show that a thin lubricant layer on the top contributes to the delayed ice formation. In our research, we compare the kinetic energy dissipation of water drop between superhydrophobic and lubricant-infused surfaces. More energy will dissipate on the lubricant-infused surfaces due to the different interface and surface energy. Drop impact phenomena on surfaces using various lubricants was examined. We prove that the water-lubricant-air interface contributes to the different drop impact events and energy dissipation. Our finding also helps to predict how the water drop will behave on the lubricant-infused surfaces. With minimum water kinetic energy dissipation on liquid-infused surfaces, a more effective self-cleaning surface was investigated and analyzed. 2015-09-15 English text University of Akron / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=akron1435735900 http://rave.ohiolink.edu/etdc/view?acc_num=akron1435735900 unrestricted This thesis or dissertation is protected by copyright: some rights reserved.
