Porous cellulose aerogel materials are attracting increasing interest due to their promising potential in multiple fields. In this paper, highly porous and mechanically strong cellulose aerogels were successfully prepared from microcrystalline cellulose and dissolving pulp in ionic liquid BmimCl via a sol–gel polymerization method. The surface morphology and physical properties were characteriz...

To study the microscopic thermal aging mechanism of insulating paper cellulose through molecular dynamics simulation, it is important to select suitable DP (Degree of Polymerization) and force field for the cellulose model to shorten the simulation time and obtain correct and objective simulation results. Here, the variation of the mechanical properties and solubility parameters of models with ...

In this work, electrically conductive cellulose nanocrystals were used to reinforce shape memory polyurethanes, adding an extra variable to tune up the properties of these nanocomposites. The modified nanocrystals were prepared by an in situ polymerization method, growing polyaniline (PANI) on the surface of the cellulose nanofibrils [3]. These crystals combine the good mechanical properties of...

In this work, nanofibrillated cellulose (NFC) has been evaluated as a potential reinforcement for cement mortar composites. Two types of vegetable fibres with different composition and properties (cellulose content and microfibrillar angle), sisal, and cotton linters pulps, were initially characterised in order to assess their reinforcing capability. Sisal pulp was found to be most suitable as ...

the usage of ceramic composites in order to improve the workability and properties of clay already has past a long history behind. in spite of the fact that clay by its own is a flexible and appropriate material for sculpting and ceramic making, it also carries some problems, flaws and imperfections (such as cracking, heaviness and etc.) which make it somehow troublesome to work with. from the ...

carboxymethyl cellulose (cmc)-polyvinyl alcohol (pvoh) blend film, containing 0-10% cellulose nanowhiskers (cnw), was produced through casting method, while physical properties of the films being investigated. cmc-pvoh-cnw nanocomposites, were prepared with a diluted suspension of cellulose nanowhiskers. nanowhiskers suspension was prepared through acid hydrolysis of cotton linter by sulfuric a...

nanofibrillated cellulose fibers were produced from unbleached kraft pulp of kenaf bast fiber. air dried and vacuum filtrated films of cellulose nanofibers were produced and their density and tensile properties were investigated. kenaf bast fiber unbleached kraft pulp has good potential for production of cellulose nanofibers by microfluidizer; so that the use of kenaf bast fiber unbleached kraf...

We have synthesised novel ionic liquids (ILs) to show both cellulose dissolution ability and LCST-type phase transition after mixing with water. To realise both polar and hydrophobic properties, tetraalkylphosphonium cations and a series of carboxylate anions were employed to assume hydrophobic and highly polar properties, respectively. Effects of their alkyl chain length on the water compatibi...

Cellulose nanofiber/AlOOH aerogel for flame retardant and thermal insulation was successfully prepared through a hydrothermal method. Their flame retardant and thermal insulation properties were investigated. The morphology image of the cellulose nanofiber/AlOOH exhibited spherical AlOOH with an average diameter of 0.5 μm that was wrapped by cellulose nanofiber or adhered to them. Cellulose nan...

The effect of paraffin wax encapsulated microcrystalline cellulose (EMC) particles on the mechanical and physical properties of EMC/epoxy composites were investigated. It was demonstrated that the compatibility between cellulose and epoxy resin could be maintained due to partial encapsulation resulting in an improvement in epoxy composite mechanical properties. This work was unique because it w...
