Model Cellulosic Surfaces: History and Recent Advances

Cellulosic Substrates for Removal of Pollutants from Aqueous Systems: A Review. 3. Spilled Oil and Emulsified Organic Liquids

“…Adamson & Gast 1997;Roman 2009 Roughness and chemical heterogeneities of cellulosic substrates can be expected to cause hysteresis effects. Thus, there will be an extra resistance to initial wetting, but once a surface has been wetted, it is then hard to retract the liquid and "de-wet" the surface.…”

Tailor-made functional surfaces based on cellulose-derived materials

“…Natural cellulose surfaces have received significant attention since the 1980s for the unique role of cellulose in nature and industries (Roman 2009). Smooth and uniform cellulose surfaces have been prepared via a variety of approaches, including (1) amorphous cellulose surfaces regenerated from trimethylsilyl cellulose (TMSC) thin films Cheng et al 2011;Kontturi et al 2003;Schaub et al 1993), (2) cellulose II surfaces regenerated from the solutions of cellulose in dimethylacetamide/lithium chloride (DMAc/LiCl) (Aulin et al 2009;Eriksson et al 2005) (Maurer et al 2012;Notley and Wågberg 2005), (3) nanocrystalline cellulose surfaces spin-coated from the aqueous colloidal suspensions of acid-hydrolyzed cellulose nanocrystals (or nanowhiskers) (Edgar and Gray 2003;Kittle et al 2012), and (4) nanofibrillar cellulose surfaces spincoated from aqueous dispersions of micro-or nanofibrillar cellulose (Ahola et al 2008a;Ahola et al 2008b).…”

“…Based on these recent developments, we foresee more application of cellulosebased materials for the fabrication of functional surfaces mentioned above with competing advantages compared to other materials, such as synthetic polymers. This minireview focuses on the functional surfaces prepared using cellulose-derived materials, while the fabrication and analysis of model cellulose surfaces from nanocellulose or regenerated cellulose (Emily and Derek 2009;Kontturi et al 2006;Roman 2009) and the studies using paper as substrates Ngo et al 2011) have been reviewed elsewhere.…”

Cellulose Langmuir-Blodgett Films for Moisture and Gaseous Molecular Sensing System

“…M. Roman has summarized the history of cellulose LB films in his recent extensive review [1]. Here, we have cited the heart of his review since the core importance is to develop the effective highly tailored cellulose LB sensing film unit for future application.…”

“…Cellulose is not only the main constituent of cell walls of a variety of plants but also one of the most important and versatile renewable resources in the world [1]. The cellulose derivative shows high sensitivity to moisture owing to its hydrophilic character on the glucose base unit and therefore a modification on side chains can act itself as ambipolar adsorber for ambient gas molecules.…”
