“…It prevents of the agglomeration of Ag nanoparticles formed through the reduction reaction by a reducing agent [24]. 0.01g graphene nanoflakes were dispersed in 10 mL DMF by ultrasonication for 1 h. The colloi dal solution of synthesized Ag nanoparticles was added to the ultrasonicated graphene suspension so that the silver to graphene weight ratio of 1 : 1 is achieved in final solution and then sonicated again for 1 h to disperse and immobilize the Ag nanoparti cles on the surface of the graphene plates [21].…”

“…The resulted colloidal solution of Ag/G nanoparticles and solution of PVC were mixed so that the desired amounts of filler phase and PVC come into contact and the mixture ultrasonicated for 2 h. The mixtures were then drop casted on a flat sur face and kept in an oven at 110°C for 1 h. After evapo ration of the solvent and dissolved PVP, transparent plastic thin film of Ag/G nanoparticles incorporated PVC nanocomposite were detached from the surface of the glass. The thickness of the prepared films in the range of 7-10 μm was measured by a precise micrometer [21].…”

“…Optical constants (refractive index n, extinction coefficient k and absorption coefficient α) of the nanocomposites were determined using trans mittance and reflectance UV-Vis spectra, at the 300-800 nm wavelength range. Intercalation of Ag nano particles to the graphene and subsequent addition of small amounts of resulted hybrid conducting phase to the PVC matrix enables us to prepare a very transpar ent and conductive film of PVC without undesired changes in the mechanical or thermal properties of the polymer [21].…”

Transparent nanocomposite PVC thin films containing the silver nanoparticles intercalated graphene (Ag/G) were prepared by simple solution blending process, followed by drop casting and annealing route. The optical properties of the nanocomposite thin films with various weight percentages of the Ag/G nanoparticles were investigated. The fundamental optical constants of the thin films were determined using the UV-Vis reflectance and transmittance spectroscopy at the wavelength range of 300-800 nm. Optical band gap has been determined from the absorption coefficient values using Tauc's procedure. The optical band gap decreases from 3.79 eV for pure PVC film to 2.12 eV for the nanocomposite thin film with 5 wt% of the filler phase. The oscillator energy E 0 , dispersion energy E d and other parameters were determined by the Wemple DiDomenico method.

In the present work, graphene was synthesized by catalytic reduction of carbon dioxide (dry ice) in presence of magnesium flame supported by zinc and nickel metal respectively. The use of Nickel resulted in the improvement of graphene yield. The multiwall carbon nanotubes (MWCNTs) were synthesized from pongamia oil in CVD setup. The synthesized graphene and MWCNTs were characterized by different characterization techniques such as scanning electron microscopy, transmission electron microscopy, Raman spectra and X‐ray diffraction study. Thus synthesized graphene and MWCNTs have been used as conductive filler in polystyrene (PS)/graphene and PS/MWCNT nanocomposites. PS nanocomposites were prepared by solution blending method using toluene as a solvent. The properties of PS/graphene nanocomposites were compared with those of PS/MWCNT nanocomposites and the graphene based nanocomposites showed improved results. Interestingly, PS/graphene nanocomposite showed good electrical conductivity (about ∼7.07 S/cm) and these also showed electromagnetic interference shielding effectiveness (–31 dB) with the loading of 10 wt% graphene in PS matrix. Thermal properties of PS/graphene nanocomposite were also studied and were found to be good. POLYM. COMPOS., 39:E1041–E1051, 2018. © 2017 Society of Plastics Engineers

Surface modification of magnesium hydroxide sulfate hydrate whiskers and its toughness and reinforcement for polyvinyl chloride

View full text Add to dashboard Cite

In order to enhance the adhesion and compatibility of magnesium hydroxide sulfate hydrate (MHSH) whiskers with polyvinyl chloride (PVC), and prepare high performance MHSH/PVC composites, chitosan (CS) is coated on the surface of MHSH whiskers by a facile method. The effect of the CS‐coated MHSH (CS‐MHSH) whisker and its toughness and reinforcement for PVC are studied. A thin layer coated on the surface of MHSH whiskers after modification is investigated by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The efficacy of surface modification is confirmed by fourier transform infrared spectroscopy (FTIR), X‐ray power diffraction analyses (XRD) and energy disperse spectroscopy (EDS). The optimum modification concentration of CS is 0.025%. The notched impact strength and flexural modulus of PVC composite with 15 phr CS‐MHSH whiskers are increased by 85.5% and 58.5% compared with those of pure PVC, and by 48.3% and 4.1% compared with those of the PVC composite with 15 phr unmodified MHSH whiskers. A better thermal stability of CS‐MHSH/PVC composite is showed by thermogravimetric analysis (TGA). Dynamic mechanical analysis (DMA) result indicates that CS‐MHSH whiskers have a better dispersion and a stronger interfacial adhesion with PVC matrix. POLYM.
