Introducing surface features on polymer systems can lead to enhancement of an existing property, improvement of structural functionality, and can even introduce a new property that is not originally present to the bulk polymer. There are a number of fabrication approaches and list of possible applications available. However, existing systems can still be improved in terms of efficiency, freedom, and application. The dissertation focuses on unconventional fabrication methods for hierarchical coatings and particles, and on some studies, their application. Hierarchical coating can be efficiently fabricated by assembly of polystyrene microparticles and subsequent electropolymerization of hydrophobic conducting polymer. The resulting coating showed superhydrophobic property and effective protection against corrosion of the underlying metal substrate. Alternative to electropolymerization is the combined layer-by-layer assembly and subsequent surface-initiated polymerization on structured polymer coating. It has been demonstrated that the above method is a very efficient method of fabricating temperature-responsive coating that can switch from being superhydrophilic to superhydrophobic. Efficient method was developed to simultaneously functionalize both sides of free-standing film by surface-initiated polymerization. Investigation of the solvent response of layer-by-layered assembled polymer film led to the development of self-folding particles. Lastly, it has been demonstrated that the combined multilayer extrusion and reactive ion etching extends the limits of current systems for hierarchical particles.
