“…The enhancement of degradation process was correlated to the reduced mobility of the polymer moiety in the presence of large amount of HNTs as monitored by dielectric spectroscopy data (Cavallaro et al, 2011a). Similar thermal degradation behavior was observed for HNTs-PEG 20000 composites (Cavallaro et al, 2013a). Concerning the residual mass after the nanocomposites pyrolysis, it generally scales linearly with the inorganic nanoparticle contents (Cavallaro et al, 2011b;2012; but some exceptions showing much larger residual mass show the enhanced char formation in the presence of HNTs likely due to the entrapment within the nanotubes lumen (Makaremi et al, 2015).…”

“…However, the main limiting factor for cellulose manufactures raised in regenerating and processing that polymer owing to its large hydrogen-bond formation ability and its crystalline structure which limit the dissolution or regeneration in conventional solvents (Cao et al, 2009). To solve this problem, a number of synthetic methodologies was developed; one of them is the etherification of the cellulose that leads to biopolymers very promising into numerous applications.…”

Scientific research has been invigorated by a new class of biodegradable materials as alternatives to polymers derived from fossils. Such biomaterials can also offer economic advantages because they are derived from renewable resources. Several biopolymers (gelatin, chitin, chitosan, starch, pectin, cellulose and its modified versions, etc.) have been exploited to produce films and formulations. Their use is limited because of fast degradation, predominant hydrophilic character, and, in some cases, unsatisfactory mechanical properties. However, the properties of these polymers can be improved by using inorganic fillers such as additives. Halloysite nanotube is a promising green filler for this purpose.

“…Chemically, ionic liquids are made of an organic cation and smaller, organic or inorganic anion [5], and the most interesting are the properties of room temperature ionic liquids (RTILs) [9]. The ability to dissolve cellulose in ionic liquids allows for a relatively simple processing of this polymer to obtain fibers [10][11][12][13][14][15][16], nanofibers [17][18][19] cellulose particles [20], cellulose gels and aerogels [21][22][23][24], flocs [25] and membranes.…”

This paper presents the results of studies on the preparation of cellulosic membranes, from a solution in 1-ethyl-3- methylimidazolium acetate (EMIMAc), using the phase inversion method. Initially, the membranes were obtained by coagulation of the polymer film in water and primary alcohols (methanol, ethanol, 1-propanol, 1-butanol, 1-pentanol), 1-hexanol, 1-octanol) resulting in membranes with significantly differing morphologies. Subsequently, composite membranes were produced, with the support layer being a membrane with the largest pores, and the skin layer a membrane with smaller pores. The resulting membranes were tested for physicochemical and transport properties. The morphology of the membrane surfaces and their cross-sections were investigated by using a scanning electron microscope (SEM). The structure of the membranes, on the other hand, was investigated by FTIR spectroscopy and WAXS structural analysis.

“…Further, it has been proposed that due to their good dissolution properties, the use of ionic liquids can aid in control of degree of substitution in for example acetylation and tosylation reactions using various ionic liquids, reaction conditions and reactants [136][137][138]. Unlike in DMAc/LiCl solutions, no catalyst seems to be needed.…”
