Facile Fabrication of Polyhedral Oligomeric Silsesquioxane Block Bonded Cellulose Paper for Efficient Oil/Water Separation
We have successfully developed a superhydrophobic and superoleophilic cellulose paper by in situ formation of polyhedral oligomeric silsesquioxane (POSS) blocks on its surface. These POSS blocks endow the cellulose paper with an optimal micro-nano structure and hydrophobic composition, resulting in superhydrophobicity and enhanced abrasion resistance. The modified cellulose paper was characterized using scanning electron microscopy, energy dispersion spectroscopy, X-ray photoelectron spectroscopy, and X-ray diffraction analysis to confirm the structures. The oil-water separation performance of the as-prepared paper was validated through preferential adsorption and gravity-driven separation processes, demonstrating high separation efficiency and throughput for various oil/water mixtures. This innovative approach provides a promising solution for large-scale oil spill accidents while offering excellent reusability and stability.
期刊介绍：
Polymer Science, Series B is a journal published in collaboration with the Russian Academy of Sciences. Series B experimental and theoretical papers and reviews dealing with the synthesis, kinetics, catalysis, and chemical transformations of macromolecules, supramolecular structures, and polymer matrix-based composites (6 issues a year). All journal series present original papers and reviews covering all fundamental aspects of macromolecular science. Contributions should be of marked novelty and interest for a broad readership. Articles may be written in English or Russian regardless of country and nationality of authors. All manuscripts are peer reviewed
