“…The impregnation method has been used to create allcellulose composites based on ligno-cellulose fibres such as ramie [242,243], rice husk [244], BC [245] and cellulose nanowhiskers [51]. Nishino and co-workers [242,243] created all-cellulose composites in which both the fibres and matrix are cellulose, by distinguishing the solubility of the matrix cellulose into the solvent from that of the fibres through a pre-treatment of the fibres.…”

This paper provides an overview of recent progress made in the area of cellulose nanofibre-based nanocomposites. An introduction into the methods used to isolate cellulose nanofibres (nanowhiskers, nanofibrils) is given, with details of their structure. Following this, the article is split into sections dealing with processing and characterisation of cellulose nanocomposites and new developments in the area, with particular emphasis on applications. The types of cellulose nanofibres covered are those extracted from plants by acid hydrolysis (nanowhiskers), mechanical treatment and those that occur naturally (tunicate nanowhiskers) or under culturing conditions (bacterial cellulose nanofibrils). Research highlighted in the article are the use of cellulose nanowhiskers for shape memory nanocomposites, analysis of the interfacial properties of cellulose nanowhisker and nanofibrilbased composites using Raman spectroscopy, switchable interfaces that mimic sea cucumbers, polymerisation from the surface of cellulose nanowhiskers by atom transfer radical polymerisation and ring opening polymerisation,

A process we term “natural fiber welding” is demonstrated by which loose fibers are transformed to create a congealed network using an IL solvent. Several examples are discussed that include cellulosic and protein‐based materials. SEM shows the fusion of fibers upon treatment. XRD and FT‐IR spectroscopy of cellulosic materials show that significant amounts of the native polymer structure are retained after the process is completed. Data suggest that material at the fiber exterior is preferentially transformed while material in the fiber core is left in the native state. Data also demonstrate that the amount of material modified can be tailored by control of variables such as the IL solvent concentration, the process temperature, and the processing time.

“…ILs can also be recycled after simple treatment (Kosan et al 2008;Abdulkhani et al 2013). Some scholars have investigated cellulose solubility (Swatloski et al 2002;Zhao et al 2009;Liebner et al 2010), separation of the three main components of wood (Wang et al 2011;Yang et al 2013;Abushammala et al 2015), and subsequent saccharification after IL pretreatment (Lee et al 2009;Fu et al 2010). Some researchers have also made wood or wood fiber plastic using ILs (Ou et al 2014a(Ou et al , 2014b(Ou et al , 2015.…”

Physical and Mechanical Properties of Modified Poplar Veneers

et al. 2017

aTo improve the performance and expand applications of poplar plantation wood, modified poplar veneers based on 1-butyl-3-methylchloride ([Bmim]Cl) were studied. Two groups of poplar veneers were impregnated in ionic liquid [Bmim]Cl (group C) and pure water (group B), separately. Techniques such as hot pressing-coagulation and bath-annealing were applied to these two groups to prepare modified samples. The physical and mechanical properties of each group were tested and characterized, using untreated group (A) as the control. The ductility and thickness variation rate of samples in group C were higher than those in group B. The width variation rate of samples in group C was 64% greater than those in group A and 50.4% greater than those in group B. Scanning electron microscopic (SEM) results also showed the plasticity and the improvement in the transverse connection of samples in group C; these results were more obvious than that for samples in group B. The tensile strength and elastic modulus of samples in group C were higher than those of group B. Compared with the control group, the crystallinity index (CrI) of samples in groups B and C was increased and that of group C was the maximum, but the crystal form remained unchanged.
