Nanofibrillated cellulose

MIC values confirmed the noticeable antibacterial activity of the fabricated polymer by the response of Enterococcus faecalis. Streptococcus pneumoniae and Staphylococcus aureus. The antimicrobial properties of pure nanofibrillated cellulose (NFC) coated with Ppy-silver composite (Scheme 7.4) films were tested on yeast Candida albicans), a Gram-negative bacterium Salmonella serovar Infantis) and a Gram-positive bacteria Listeria monocytogenes and Staphylococcus aureus) (Table 7.3) [60].

Furthermore, composite films of nanofibrillated cellulose (NFC)/Ppy and NFC/ PPy-silver NP are a suitable candidate for use in biomedical applications. Due to the electrical conductivity and strong antimicrobial activity of these silver composites, they can be used in various applications, in particular, biomedical treatments and diagnostics.

The cellulose based materials that are used as nano-reinforcements are cellulose nanocrystals (i.e. whiskers and nanospheres), nanofibrillated cellulose, regenerated cellulose nanoparticles and electrospun nanofibers. A wide range of polymer matrices have been used to form cellulose nanocomposites. Synthetic polymers such as polypropylene, poly(vinyl chloride) (PVC) [102], waterborne epoxy [103], waterborne polyurethane [104], polyurethane [105], poly-(styrene-co-butyl acrylate) [106], poly(oxyethylene) [107], polysiloxanes [108], polysulfonates [109], cellulose acetate butyrate [110,111], poly(caprolactone) [112], poly(viny 1 alcohol) [113] and poly (vinyl acetate) [114].

Nonwoven mats of cellulose microfibrils were also used to prepare polyurethane composite materials via film stacking method [160], Water-redispersible nanofibrillated cellulose in powder form was recently prepared from refined bleached beech pulp by carboxymethylation and mechanical disintegration [161], However, the carboxymethylated sample displayed a loss of crystallinity and strong decrease in thermal stability limiting its use for nanocomposite processing.

Several terms are used to denote the nanocellulose obtained by a technique of high-pressure (high-shear) mechanical disintegration of cellulose pulp, namely microfibrillated cellulose, nanofibrillated cellulose, nanofibers, etc. Here we use predominantly the term nanofibrillated cellulose. ...

The fracture work (in-plane tear) of a medium consisting of small particles only, such as filler and nanofibrillated cellulose, is low. It can be considerably enhanced by adding reinforcement pulp fibres. Any particle crossing the rupture path must be released from the paper structure by bond failure, or it must be inactivated by fibre... [Pg.142]

Different descriptors have been used in the literature to designate the crystalline rod-like nanoparticles. These particles are mainly referred to as whiskers, nanowhiskers, cellulose nanocrystals, NCC (nanocrystalline cellulose), monocrystals, microcrystals, or microcrystallites, despite their nanoscale dimensions. The terms microfibrils, microfibrillated cellulose (MFC), and nanofibrillated cellulose (NFC) are used to designate cellulosic nanoparticles obtained by a simple mechanical shearing disintegration process (Fig. 7.2) as described in the next section.
