Nanocomposite hydrogels were developed by cross-linking nanofibrillated cellulose with poly(methyl vinyl ether-co-maleic acid) and polyethylene glycol. The cross-linked hydrogels showed enhanced water absorption and gel content with the addition of nanocellulose. In addition, the thermal stability, mechanical strength, and modulus increased with an increase in the amount of nanocellulose in hyd...

Nanocomposite polymer electrolyte membranes (NCPEMs) based on poly(acrylic acid)(PAA) and titania (TiO2) are prepared by a solution casting technique. The ionic conductivity of NCPEMs increases with the weight ratio of TiO2.The highest ionic conductivity of (8.36 ̆ 0.01) ˆ 10 ́4 S ̈ cm ́1 is obtained with addition of 6 wt % of TiO2 at ambient temperature. The complexation between PAA, LiTFSI and T...

The presented work shows the synthesis and characterization of Zn/Ti layered double hydroxide (LDH) intercalated with carbonate dodecyl sulfate ions following its application as a functional filler in LDPE order to improve thermal properties resistance degradation UV-Vis radiation. X-ray diffractogram patterns LDH-CO3 LDH-DDS present basal spacing value 6.81 Å 38.09 Å, respectively, indicating ...

Experimental observations indicate substantial differences in the rheology and dynamics of polymer liquids reinforced with colloidal and nanosize particles compared to complex fluids filled with micron sized particles (Reynaud et al. 2001; Zhang and Archer 2002, 2004; Donnet 2003). The filler size effect on the overall material behavior has been attributed to either inter-particle or polymer-pa...

INTRODUCTION The combination of hardness, scratch resistance and flexibility is a highly desired feature in many coating applications. A potential route to achieve this aim is via the introduction of a nanoparticle filler into the polymer resin. The great interest for using nanoparticles to reinforce polymers emerged in the late 1980s when a research group from Toyota reported their findings re...

Photoalignment layers comprising Polymer 1 were prepared using linearly polarized UV-irradiation for chloroformvapor annealing of p-conjugated oligomer films, both processes conducted at room temperature. The resultant uniaxially oriented monodomain films exhibited S 1⁄4 0.74 (at Pr 1⁄4 0.90) and 0.82 (at Pr 1⁄4 0.95) in OF and OF2T films, respectively, apparently limited by film dewetting in c...

* Corresponding Author Email: [email protected] Objective(s): The main aim of current research was to develop a novel magnetically responsive hydrogel by radical polymerization of carboxymethyl cellulose (CMC) on acryl amide (Am) using N,N'-methylene bis acrylamide (MBA) as a crosslinking agent, potassium persulfate (KPS) as a free radical initiator, and magnetic montmorillonite ( mMT)...

Extrudate swell is often observed to be weakened in nanocomposites compared to the pure polymer matrix. A theory quantifying this would be significant either for optimum processing or for understanding their viscoelasticity. A unified extrudate swell correlation with material properties and capillary parameters was suggested for polymer melt and their nanocomposites when considering the reservo...
