Effect of metal nanoparticles on thermal stabilization of polymer/metal nanocomposites prepared by a one-step dry process

The Addition of Aluminum Nanoparticles to Polypropylene Increases Its Thermal Stability

“…At all the heating rates used, the T m of the PPAl5 was some 4 ºC higher than that of the iPP (mean 457.2±2 ºC compared to 453.4±2 ºC). A similar increase was described by Lee et al [20] for a PP sample incorporating Pd nanoparticles. FTIR spectra have shown the existence of several interactions between a polyvinylidene fluoride matrix and Al nanoparticles in nanocomposites similar to the present PPAl5 [29].…”

“…These values are similar to those reported in the literature for iPP. Lee et al (2006) reported a value of 229 ± 13 kJ/ mo l as determined by the Fried man method (with an A value of 6.5x10 15 min -1 ), and of 228 kJ/ mol as determined by the Kissinger method For the PPAl5, the E a was 244 ± 4 kJ/ mo l (A = 1.6x10 17 min -1 ) as determined by the Fried man method, 242 ± 4 kJ/ mo l as determined by the FWO method, and 244 kJ/ mol as determined by the ASTM E698 method. Thus, the E a of the PPAl5 was around 15 kJ/ mol higher than that of the iPP: adding the Al nanoparticles therefore improved the thermal stability of the iPP.…”

“…Several studies have examined the degradation features of polymer nanocomposites [14][15][16][17][18] but only a few have dealt with the thermal degradation kinetics of PP nanocomposites that incorporate metal particles [19,20]. The present work examines the thermal stability of pure PP and PP/Al nanocomposites in an N 2 at mosphere using TGA.…”

Preparation of Micro-sized Ni-P alloy Tube by Electroless Plating on PAN Fiber/Pd Nanoparticle Using a Drying Process

“…In our previous works, we found that ZnO and Ni-P alloy were site-selectively deposited on palladium (Pd) loaded or platinum (Pt) loaded polymer thin film [6][7][8], and we also found that palladium(II) bis(acetylacetonate), Pd(acac)2 and platinum(II) bis(acetylacetonate), Pt(acac)2 were sublimed at 180 o C in vacuum condition and the Pt(acac)2 vapors penetrated into polymer film and spontaneously reduced forming metallic (Pd and Pt) nanoparticles [9,10]. Therefore we could develop a new method to prepare micro-sized Ni-P alloy tube via using a polyacrylonitrile (PAN) fiber with μm sized diameter as a template.…”

Self‐Assembling of SBS Block Copolymers as Templates for Conductive Silver Nanocomposites

“…To obtain metal-polymer nanocomposites with well-defined structures and properties that can be reproduced properly, a subtle control over nanoparticles growth, particle size distribution and particle-interface interaction must be maintained. [6][7][8][9][10] The metal-polymer interactions require special attention and a proper interface can be normally generated by using hydrophobic-hydrophilic surfactant materials. [11][12][13][14][15][16][17][18] In this study, nanocomposites of Ag nanoparticles embedded in polystyrene-block-polybutadiene-block-polystyrene (SBS) block copolymer were investigated.…”
