“…Moreover, nanoparticles, such as organophilic layered silicates, metal oxides, and carbon nanotubes, were also used to blend with PS to improve its thermal and mechanical properties (e.g., thermal stability, stiffness, strength, creep‐resistance properties) . The compounding of PS with both rubber and rigid nanoparticles has attracted considerable attention because of the promise of simultaneous improvements in the stiffness and toughness . It has been shown that bentonite clay could compatibilize and reinforce the natural rubber/PS system via a latex blending process .…”

Polystyrene (PS) foams have been used in various fields, whereas its broader application is limited by its low mechanical strength and brittle features. In this study, styrene-butadiene-styrene (SBS) and calcium carbonate (CaCO 3 ) nanoparticles were meltblended with PS and extrusion-foamed with supercritical carbon dioxide as a blowing agent to simultaneously toughen and reinforce PS foams. Under the same foaming conditions, the addition of SBS and CaCO 3 was shown to have a significant influence on the cell structure and the compressive properties of the composite foams. We found that the cell structure evolution was highly correlated with the system viscosity. When the rubbery-phase SBS content was 20%, the cell diameter decreased by 20.7%, and the compressive modulus was enhanced by 289.5%. With the further addition of 5% rigid CaCO 3 nanoparticles, the cell diameter was further reduced by 72.2% and the compressive modulus was improved by 379

Polymeric nanoparticles have many advantages as the reinforcing filler of rubber. To investigate the mechanism of the reinforcement, nanocomposites of poly (styrene-butadiene) rubber (SBR) filled with polystyrene (PS) particles as the reinforcing agents was prepared. Morphology and dynamical mechanical properties of PS particles-filled SBR were investigated. It was found that the polymer chains of the elastomer could be absorbed onto the PS particles, in reminiscent to the concept of bound rubber in inorganic filler-filled elastomeric system. The adsorbed polymer layer can form up glassy bridges between neighboring filler particles, leading to the agglomeration of the filler particles and the reinforcement of the elastomer. With higher filler content or smaller filler size, the numbers of the glassy bridges increase, and the modulus of the elastomer increases. With higher strain or higher temperature, the filler-filler interaction is disrupted and the material is softened. The study discovered the existence of bound rubber in PS particles-filled elastomer and illustrated its influence on the dynamic mechanical properties, which could be helpful to design the polymeric nanoparticles for rubber reinforcement.

ABSTRACT:Polymer blends between polyaniline (PANI) nano/large particles and chloroprene rubbers were fabricated and investigated as the electroresponsive materials. The effects of the chloroprene type, particle size, particle concentration, and electric field strength on the electrical properties, the storage modulus sensitivity, and the dielectrophoresis force were studied. Chloroprene W provides the highest storage modulus sensitivity at 55% and is chosen as the matrix. The electrical conductivity and the dielectric constant of the blends increase with an increasing concentration of PANI nano/large particles. The storage modulus of the blends (with and without the electric field) increases linearly with the PANI content. The maximum storage modulus sensitivities of the blends with PANI nano and large particles at E = 2 kV/mm are 73% at 0.01 vol% and 63% at 0.1 vol%, respectively. The dielectrophoresis force of all specimens increases monotonically with increasing electric field strength. The blends with PANI-nano and large particles at 0.01 vol% generate higher dielectrophoresis forces than those of the pure chloroprene W. For the 0.1 vol% of PANI nano and large particles, the resultant deflection angle and dielectrophoresis forces are lower than those of the 0.01 vol% systems and the pure chloroprene W, presumably due to the diminishing resultant dipole moments generated with increasing PANI concentration.
