Special Issue Information

Dear Colleagues,

While materials were initially employed for their bulk properties and have led to an overwhelming wealth of new products for structural uses in the past century, advancing applications have now shifted focus to gaining control over materials surface properties. For instance, low-friction and wear-resistant treatments are sought after to maximize tools lifetime or to produce self-cleaning surfaces. On the other side of the spectrum, methods for specific adhesion are developed. Surfaces of implant biomaterials are designed to provide a superior compatibility with the receiving organism, while governing stability/degradability features. Further, surfaces that can change their properties depending on the environmental conditions allow for a dynamic and adaptable behavior. In addition to the specific properties of a surface, particular attention is devoted to specifically manipulate these in space through the formation of patterns possessing domains with antagonistic features, such as in array production.

The present Special Issue on “Chemical Surface Modification” is meant to host a variety of topics related to the aforementioned aspects. Therefore, reports dealing chemical procedures to modify the surface properties of any material, be it inorganic or organic, and patterning methods are expected. Contributions on simple coatings obtained by non-reactive deposition of a substance will not be considered, except if the coating itself is used for further modification. Not only is it important to develop new chemical methodologies for surface modification, but also means to assess them. Therefore, contributions dealing with advanced surface characterization techniques are also encouraged. Please refer to the non-exhaustive list of keywords for further hints.

Reviews, full papers, and short communications are welcome.

An anionic adsorbent was prepared by grafting citrate onto pomelo peel (PPL) to remove methylene blue (MB) from aqueous solution. The PPL and modified pomelo peel (MPPL) were analyzed by Fourier transform infrared spectroscopy (FTIR) and observed by scanning electron microscopy (SEM). The effects of dye concentration, contact time, and pH on adsorption were studied. The FTIR results confirmed that the carboxyl groups were successfully bound to cellulose molecules in PPL via modification with citrate. SEM indicated that the surface of PPL became clean and the porous structure was well maintained after modification. The adsorption capacities of MB onto PPL and MPPL were 81.7 mg/g and 199.2 mg/g, respectively, thus indicating that the addition of anionic groups significantly improved the adsorption performance. The increase in the initial dye concentration and pH of the dye solution promoted the adsorption process. The adsorption equilibrium on MPPL required approximately 3 h. The adsorption of MB on MPPL was well described by a pseudo-second order kinetic model and Langmuir isotherm model. The thermodynamic parameters indicated spontaneous and exothermic adsorption. This study suggests that PPL modified with citrate can be used as a sustainable adsorbent in wastewater purification. Full article
