Nano whiskers

D layered compounds as well. A related method for the synthesis of WS2 nanotubes is to first synthesize crystalline and long W18049 nanowhiskers, and subsequently sulfidize these nano whiskers (10,31). This method yields large amounts of very long (30 (t) WS2 nanotubes, often with nonclosed caps. [Pg.284]

More recently, individual chitin nano-whiskers have been prepared from partially deacetylated a-chitin by fibril surface cationization. When CWs with degrees of N-acetylation (DNAc) 0.74—0.70 were mechanically disintegrated in water at pH 3, individualized nano-whiskers with average width and length of 6.2 1.1 and 250 140 nm respectively, were successfully prepared, as reported by Fan et al. [52] the driving force for individualization of CWs is the same as that in... [Pg.62]

Abstract Biopolymers are expected to be an alternative for conventional plastics due to the limited resources and soaring petroleum price which will restrict the use of petroleum based plastics in the near future. PLA has attracted the attention of polymer scientist recently as a potential biopolymer to substitute the conventional petroleum based plastics. The chapter aims to highlight on the recent developments in preparation and characterization of PLA blends (biodegradable and non-biodegradable blends), PLA composites (natural fiber and mineral fillers) and PLA nanocomposites (PLA/montmorillonite, PLA/carbon nanotubes and PLA/cellulose nano whiskers). [Pg.361]

The recorded history of short fiber technology starts over two thousand years ago with asbestos fibers and reaches into the future with silicon nano-whiskers and carbon nanotubes. Asbestos is derived from the solid phase, but today, the most important short inorganic fibers are derived from the vapor phase. [Pg.11]

Cuboid and cycloid niobium monocarbide (NbC) whiskers, 0.1-2.0 pm in diameter and 5-100 pm in length, and having a square-shaped tip, were recently synthesized by heating mixtures of niobium oxide (Nb203) and carbon black at temperatures over 1100°C [38]. Silicon carbide nano-whiskers, 20-50 nm in diameter and 2-5 pm in length, were carbothermally synthesized by reducing ultrafine precipitated silica powders with ultrafine carbon black by microwave heating [29]. These processes proceed without addition of metal particle catalysts, and therefore by a VS phase transformation [14] [29] [38]. [Pg.23]

CNC is derived as nanowhiskers for use as reinforcement in biopolymers such as starch, PLA, and PHB. Apart from being biodegradable, these nano whiskers have high specific strength and stiffness. Similarly, chitin nanowhiskers are synthesized from chitin, the second most abundant biopolymer after cellulose. These nanowhiskers have many desirable properties for use as reinforcements, like low density, nontoxicity, biodegradability, biocompatibility, easy surface modification, and functionalization. Starch nanoparticles (SNP) are synthesized from starch granules for use as reinforcement. [Pg.530]

A new type of biobased material was synthesized from cellulose nano whiskers (CW) and furfuryl alcohol by employing in-situ polymerization method to produce polyfur-furyl alcohol (PFA)/cellulose nanocomposites without the use of solvents or surfactants. Furfuryl alcohol (FA) played a dual role, serving both as an effective dispersant for the cellulose whisker (CW) and as the matrix precursor for the in-situ polymerization. The filler, CW also served multiple functions, by first catalyzing the polymerization of FA, and then acting as an effective matrix modifier, increasing the thermal stability of the consolidated PFA nanocomposite. The polymerization was catalyzed by sulfonic acid residues at the CW surface left over from the whisker preparation [67]. [Pg.152]

The nanocellulose/PANI composite shows the combination behavior of PANI and nanocellulose at elevated temperature (Figure 1.8(b)). The improved thermal stability is due to the protecting layer of PANI formed on the cellulose—nanowhisker surface. The maximum degradation rate increases with an increase in the concentration of aqueous cellulose suspension. The composites containing 20wt% PANI remain 37—40% at the aqueous nanocellulose concentration of 0.1—2.0 wt%. The composites show improved thermal stability resulting from PANI coating on the surface of cellulose nano whiskers. [Pg.18]
