A Review On The Role Of LbL Technique In Post Modification Of Polymeric Sponges

Abstract

Multipurpose and multilayered layer-by-layer (LbL) coatings have been a topic of interest to researchers for many years. The main reasons for this situation are the versatility of the approach and the wide range of applications that continue to increase steadily. Since the controlled surface modification is also the key to developing advanced materials, the preparation of nano-structured materials based on LbL and the investigation of their application areas are becoming more and more popular. Among the application areas covered in these studies -preventing/improving environmental pollution, protecting ecological balance and environmental resources, observing economic sustainability, etc. also highlighting- waste treatment, membrane applications, superhydrophobic coatings, ultraviolet protective coatings, electroactive coatings, cell applications, etc. exists. Superhydrophobicity and materials with superhydrophobic property are of great interest in both academia and industry due to their self-cleaning properties. With the progress of nanotechnology, it is possible to control surface architecture and surface chemistry to achieve superhydrophobicity. Thanks to the uniqueness of superhydrophobic surfaces, advancements in this area are expected to continue for decades. This review study focuses on sponge sorbents recommended for the removal of oily pollutants/organic wastes in water, which is one of the environmental problems that have become more difficult to control in recent years. In this context, the advantages/disadvantages of polymeric sponges with essentially hydrophobic/superhydrophobic character, as well as the various properties that have been imparted to sponge sorbents with the LbL technique, have been reviewed.
