Superhydrophobic Polymer Coatings PDF Download

Surface properties play critical roles in determining the durability and overall performance of polymeric materials for applications in many different fields. Recent investigations on naturally superhydrophobic surfaces such as plant leaves and insect wings led to a clear understanding of the close relationship between surface topography, roughness, chemical structure and superhydrophobicity. This led to a dramatic increase in research efforts on the preparation and characterisation of polymeric systems with superhydrophobic surfaces. Current and potential uses of such materials in a wide range of applications also make them commercially very attractive.The main focus of this book is to provide a comprehensive overview of the new developments regarding the preparation and characterisation of superhydrophobic polymeric surfaces. A large number of methods used in the preparation of robust and durable superhydrophobic polymer surfaces and their advantages and disadvantages are discussed. Close relationship between the polymer composition, hierarchical micro/nano surface topography and superhydrophobic behavior are provided. In addition to the practical aspects, special emphasis is also given to the discussion of the theoretical foundations of the wetting behavior of rough surfaces.Nature is the ultimate guide for the preparation of functional materials and surfaces. As discussed in detail in the book, using biomimetic approaches it is possible to design and produce superhydrophobic surfaces with interesting functionalities. The most critical tasks for the scientists and engineers working in the field seem to be; (i) to clearly understand the relations between surface compositions, topography and surface properties; (ii) to develop simple laboratory techniques and commercially viable production methods to produce superhydrophobic surfaces and devices mimicking the natural systems; and (iii) to demonstrate novel applications in research laboratory and develop commercial applications for these materials with smart and multifunctional surfaces.This book provides a clear understanding of the theoretical foundations of superhydrophobicity together with practical experimental guidance for the preparation of such polymeric surfaces to researchers and application engineers working in the field.
