“…Figure 4 showed that T g of SBR nanocomposites were higher than VZ-SBR (265 8C). In Figure 4, T g of MW/SBR nanocomposites constantly increased for MW/SBR [1][2][3][4] (263 to 255 8C), showed stability for MW/SBR 5-6 (253 8C) and again decreased in MW/SBR 7 (258 8C). Whereas in Figure 5, T g of BW/SBR nanocomposites were gradually increased for BW/SBR 1-5 (264 to 256 8C) and then constantly decreased for BW/SBR 6-7 (260 to 262 8C).…”

The purpose of this study was to investigate the effect of bare wollastonite (BW) and modified wollastonite (MW) nano‐rods into the styrene butadiene rubber (SBR). SBR nanocomposites were prepared by the incorporation of different wt % (0.3–4.5) of BW and MW nanorods. All nanocomposites were characterized by thermal gravimetric analyzer (TGA) and differential scanning calorimeter (DSC). The particle size and morphology of BW and MW nanorods were characterized by field‐emission scanning electron microscope (FE‐SEM), transmission electron microscope (TEM), and Fourier transform infrared (FTIR) spectrophotometer, while FE‐SEM and AFM analyses were performed for BW/SBR and MW/SBR nanocomposites. The obtained results revealed the existence of stronger interaction between the SBR and MW nanorods into MW/SBR as compared to BW/SBR nanocomposites. FE‐SEM and AFM images showed a perfect dispersion of the MW nanorods in SBR matrix at 3 wt % loading. Thermal stability of MW/SBR nanocomposites was also increased significantly by the addition of MW nanorods. © 2015 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2015, 132, 42811.

“…[9][10][11][12][13] One approach is the addition of mineral nanofillers such as surface-modified calcium carbonate nanoparticles. Various researchers have synthesized mineral nanofillers, [14][15][16][17][18][19] but they studied its effect on biodegradation. The use of nanomaterials can overcome the poor thermal, mechanical, and limited gas barrier properties of PLA, which prevented its usage in industrial packaging sectors.…”

Biodegradation of Isotactic Polypropylene (iPP)/Poly(lactic acid) (PLA) and iPP/PLA/Nano Calcium Carbonates Using Phanerochaete chrysosporium

et al. 2016

Phanerochaete chrysosporium species was used to study the degradation of polymeric composites of (a) isotactic polypropylene (iPP) and (PLA) (iPP/PLA), and (b) iPP/PLA filled with calcium carbonate nanoparticles (nCaCO 3 ). PLA was synthesized using L-lactic acid under the controlled ultrasound cavitation technique, dried and used for composite preparation. Meanwhile, the synthesis and subsequent surface modification of nCaCO 3 was done using the ultrasound cavitation technique. Owing to ultrasound cavitation, a reaction mixture is dispersed uniformly but at the same time strong electrostatic force of attraction is developed over the surface of nCaCO 3 particles, which forms the agglomeration of particles. The deagglomeration as well as charge nullification was achieved using surface modification of CaCO 3 nanoparticles with triethoxy vinyl silane (TEVS) under controlled stirring. The sheets of iPP/PLA and iPP/PLA/nCaCO 3 were prepared at normal condition and subjected to a degradation study in minimal medium using P. chrysosporium microorganism up to 28 days. The growth of microorganism and fractures inside the polymer matrix before and after degradation was observed using a scanning electron microscope. Changes in extracellular protein content, biomass production, and percent degradation with respect to time of incubated samples have also been studied. It was found that the iPP/PLA/nCaCO 3 (5 phr) and iPP/PLA (at 30% PLA) composites show an increment in degradation. The presence of nCaCO 3 leads to faster degradation of iPP/PLA/nCaCO 3 nanocomposites, which decreases the mechanical property by 30% of PLA and 5 wt% of nCaCO 3 content.

“…Some investigations have been done to improve the properties of polymers by the addition of inorganic nanofillers such as CaCO 3 and Mg (OH) 2 . [20][21][22][23][24][25] Recently, nanocomposites based on polypropylene (PP) constitute a major challenge of industry since they enhance the mechanical and physical properties of PP. 26 However, investigations have been conducted to broaden the application of PP by improving properties such as strength, impact resistance, and thermal stability.…”

Optimized Synthesis of nTiO₂ Using Murraya koenigii Leaf Extract and Its Application in iPP–EPDM Blends

et al. 2015

The present study deals with the green synthesis of titanium dioxide nanoparticles (nTiO 2 ) using Murraya koenigii leaf extract without any catalyst, template, and surfactant. Colloidal nTiO 2 were synthesized by reacting aqueous titanium(IV) isopropoxide with M. koenigii leaf extract under controlled ultrasound cavitation. This study significantly deals with (i) the concentration of titanium(IV) isopropoxide, (ii) the concentration of M. koenigii leaf extract, (iii) rate and time of reaction, (iv) intensity and pulse rate of ultrasound, which had been investigated and optimized for the controllable size and shape of nTiO 2 particles. The size and shape of nTiO 2 particle were confirmed by using transmission electron microscopy, whereas the size was calculated from XRD spectra using Scherer's formula. Moreover, the effect of nTiO 2 particle on properties of isotactic polypropylene-ethylene propylene diene monomer (iPP-EPDM) blends was studied. The physical properties (mechanical, thermal, and swelling) were found to be improved significantly with increasing amount of loading of nTiO 2 particles. This increment in properties was due to uniform dispersion of nTiO 2 particles, which can be clearly observed in FE-SEM. C 2015 Wiley Periodicals, Inc.
