Synthetic membrane technology has achieved a startling rate of development over the last three decades. Many, if not most, of the membrane materials useful for separation processes, drug release, reactor media, and other applications are dependent on the formation and properties of thin films, often ultra-thin surface or interfacial films. Our understanding of these systems involves knowledge of the relationships between materials composition, structure and properties as affected by processing and end-use conditions. A better understanding of the scientific basis of these relationships would serve as a stimulus and guide for obtaining even more dramatic systems and applications. Areas of great promise and much accomplishment are the substitution of synthetic materials for natural biological or botanical membranes, extension of the scope of viable separation membrane applications and formation of complex membrane reactor systems. All of these areas, and others, would benefit greatly from such an increase in knowledge. This Special Issue is intended to provide a means for communicating studies that increase our scientific knowledge of thin film and membrane systems. Its content also will reflect advances reported in other relevant Special Issues of Polymers.Prof. Dr. Charles Rogers
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. Papers will be published continuously (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are refereed through a peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page.

Abstract: The influence of cholesterol molar concentration on the formation of buckling structures is studied in a physisorbed polymer-tethered lipid monolayer system using epifluorescence microscopy and atomic force microscopy (AFM). The monolayer system, built using the Langmuir-Blodgett (LB) technique, consists of 3mol% poly(ethylene glycol) (PEG) lipopolymers, and various concentrations of phospholipids and cholesterol. In the absence of cholesterol, AFM micrographs show only occasional buckling structures, which are caused by the presence of the lipopolymers in the monolayer. In contrast, corresponding AFM data illustrate that a gradual increase of cholesterol concentration in the range of 0-40mol% leads to a significant increase in monolayer roughness and the additional formation of buckling regions. These findings confirm that membrane buckling in physisorbed polymer-tethered membranes can be controlled through adjustment of membrane elastic properties. Our results are significant because they offer an intriguing perspective about the role of cholesterol on the materials properties in complex membrane architectures.
