Nanocomposites halloysite

Du et al. (50) reported the synthesis of butadiene styrene rubber nanocomposites with halloysite nanotubes. The tensile properties of the composites containing various amounts of nanotubes are depicted in Table 2.2. The tensile properties were observed to significantly increase as a function of increasing amount of nanotubes in the composites. For the maximum loading of the nanotubes, a tensile modulus of 5.56 MPa was observed as compared to 1.52 MPa for the pure polymer. [Pg.32]

Well-defined coaxial tubular halloysite nanotubes (HNTs)/PPy nanocomposites were synthesized for use as electrode materials for supercapacitors by the in situ chemical oxidative polymerization method based on self-assembled monolayer amine-functionalized HNTs [72]. It showed their greatest conductivity (40 S/cm) at room temperature and a weak temperature dependence of the conductivity from 298 K to 423K. A maximum discharge capacity of 522 F/g after correcting for the weight percent of the PPy phase at a current density of 5 mA/cm in a 0.50 mol/L Na SO electrolyte solution could be achieved in a half-cell setup configuration for the HNTs/PPy composites electrode. [Pg.438]

Sepiolite is a fibrillar silicate which has been also used as a nanoclay in PLA, compared with both montmorillonite and halloysite. The use of pillared serpentines as support for ZnO catalyst for PLA polymerization has been recently reported. Zhang et al. obtained vermiculite/PLA nanocomposite by in situ polymerization of the PLA °. The use of different synthetic micas as nanofillers in PLA has also been evaluated. ... [Pg.218]

Nanocomposites of plasticized starch with halloysite nanotubes (HNT) were investigated for their use in controlled drug delivery applications and showed retarding of drug release. They exhibited swelling, which depends on temperatme but not pH [46]. Nanocomposites of starch with bis-demethoxy curcumin analog loaded Chitosan also showed retarded and sustainable drug release [47]. [Pg.493]

Clay minerals, the micas, chlorite, serpentine, talc, between them can also find within the group of minerals phyllosilicates or layered silicates. They all have different morphology, structure, and texture (Bergaya et al. 2009). The some representative layer silicates used mainly in nanocomposites-based starch are listed in Table 2. It is important to note that the some phyllosilicates do not display a normal layered strucmre, for example, the sepiolite shows a fibrous structure meanwhile halloysite has spheroidal aggregates morphology (Duquesque et al. 2007 Bergaya et al. 2009). [Pg.43]

The dispersion state of a typical phyllosilicate (except sepiolite and halloysite) in a matrix polymer depends on the preparation conditions and the matrix-nanolayer affinity. This effect determines the structure of the resulting composites, which can be either phase separated composites (microcomposites), intercalated nanocomposites, or exfoliated nanocomposites (Alexandre and Dubois 2000). [Pg.44]

Styryltropylium (a carbo-cation) was used to modify clay for producing PS nanocomposites by in situ emulsion polymerization (Table 3.4) [60]. The resulting nanocomposites exhibited a mixture of intercalated and exfoliated structures. The nanocomposites exhibited improved thermal stability and fire retardancy. Halloysite nanotubes (HNT) are a kind of aluminosilicate clay with a hollow nanotubular structure (about 20-50 nm in diameter and several hundred nanometers in length) [61]. HNT was modified with y-methacryloxypropyltrimethoxysilane to produce a nanoclay (Table 3.4). HNT/PS nanocomposites were prepared by in situ bulk polymerization. The thermal stability of the HNT/PS nanocomposites was better than that of the pure polystyrene. [Pg.82]

Guo et al. has shown the interfacial interaction in the nanocomposites between carboxylated SBR and halloysite nanotube (HNT) [106]. Lower content of HNT tends to impediment the vulcanization of SBR/HNT compounds, while higher HNT loading promotes the vulcanization presumably due to polar interactions. It is noteworthy to mention that HNT are dispersed uniformly in the matrix with strong interfacial bonding between SBR and HNT. [Pg.29]
