The development of economically and ecologically viable strategies for superhydrophobization offers a vast variety interesting applications in self-cleaning surfaces. Examples include packaging materials, textiles, outdoor clothing, microfluidic devices. In this work, we produced superhydrophobic paper by spin-coating dispersion nanostructured fluorinated cellulose esters. Modification nanocrystals was accomplished using 2 H,2 H,3 H-perfluorononanoyl chloride H-perfluoroundecanoyl chloride,...
Cellulose-based films can potentially replace non-biodegradable plastic in various applications such as food packaging. In this work we produced and studied made of mixtures chemical pulps catalytically oxidized microfibrillated cellulose. The were prepared on a support which was then soaked solutions CaCl2 MgCl2 to exchange the sodium ions originally present film divalent metal cations. We assumed that electrostatic interaction anionic pulp fibers fibrils with Ca2+ Mg2+ would promote...
One of the main trends in developing bio-based materials is to improve their mechanical and physical properties using MFC derived from sustainable natural sources compatible low-cost chemicals. The strength anionic based can be increased with addition multivalent cations. However, direct mixing solutions cations oxidized may result immediate, uncontrollable fibril aggregation flock formation. aim this study was design a method where Ca2+ ions liberate solid CaCO3 particles on bleached...
