The development of biobased materials with lower environmental impact has seen an increased interest these last years. In this area, nanocelluloses have shown a particular in research and industries. Cellulose nanocrystals (CNC) cellulose nanofibrils (CNF) are both known to stabilize oil-water interfaces, forming the so-called Pickering emulsions which surfactant-free, highly stable armored by layer solid particles. This work describes emulsion's characteristics properties according particle...
Thermal superinsulating properties of biobased materials are investigated via the structuration aerogels through a biphasic system. Highly stable Pickering emulsions produced using TEMPO-oxidized cellulose nanofibrils (NFC) adsorbed at an oil/water interface. NFCs form entangled system clusters droplets that lead to excellent mechanical properties. The strong gels further used as template aerogels. freeze-dried result in porous bioaerogels with extremely low densities (0.012-0.030 g/cm3). We...
Cellulose nanocrystals (CNCs) are sustainable rod-shaped nanoparticles able to adsorb at oil–water interfaces produce highly stable Pickering emulsions with enhanced mechanical properties.
Nanocelluloses can be used to stabilize oil–water surfaces, forming so-called Pickering emulsions. In this work, we compare the organization of native and mercerized cellulose nanocrystals (CNC-I CNC-II) adsorbed on surface hexadecane droplets dispersed in water at different CNC concentrations. Both types CNCs have an elongated particle morphology form a layer strongly interface. However, while thickness formed with CNC-I is independent concentration 7 nm, CNC-II forms ranging from 9 14 nm...
Abstract Nanocelluloses occur under various crystalline forms that are being selectively used for a wide variety of high performance materials. In the present work, cellulose fibers (CF-I) were mercerized by alkaline treatment (CF-II) without molar mass variation (560 000 g/mol) and both acid hydrolyzed, forming nanocrystals in native (CNC-I) (CNC-II) forms. This work establishes detailed characterization these two nanoparticles morphology (light neutron scattering, TEM, AFM), surface...
