Effects of interface on the physical properties of nanoparticle-filled composites

Jang K.H., Kim B.C., Hanyang University, KR

The effects of interface affinity on the rheological responses of nanoparticle suspended polymer solutions were investigated. The polarity on rheological properties of zinc oxide (ZnO) nanoparticle filled-polymer solution was investigated for polyacrylonitrile (PAN) and polystyrene [...]

Efects of silver nanoparticle on the physical properties of syndiotactic polypropylene

Kang E.C., Kim B.C., Hanyang University, KR

The effects of silver nanoparticle on the physical properties of syndiotactic polypropylene (sPP) were investigated in terms of rheological responses and crystallization behavior under shear. Silver nanoparticle played as the nucleating agent of sPP by [...]

Surface modification of Cp-Titanium by Plasma polymerization of acrylic acid

Park H.J., Park S-J, Cho D.L., Park H.J., Park S-J, Ko Y.M., College of Dentistry, 2nd stage of brain korea 21, Chosun University, KR

Cp titanium sheet (15 mm x 15 mm) was used to two different surface treatments, including, etching with an HCl/H2SO4 solution and non-treated bare Ti sheet. To improve the adhesive strength of AA films, we [...]

Strain-induced Crystallization and Mechanical Properties of Carbon Nanotubes Reinforced Natural Rubber

Jeon H.-J., Kang M.K., Song H.H., Kwag G., Choi H., Hannam University, South Korea, KR

Natural rubber is an elastomeric material and its ability to crystallize at large deformations results in an extraordinary toughness. However, natural rubber needs the reinforcing materials to improve the mechanical strength, thermal stability and abrasion [...]

Ferritin-based Hybrid Nanofibers with Magnetic Properties

Shin M.K., Cho Y., Kim S.J., Hanyang University, KR

There has been intense interest in polymeric nanocomposites using nanoparticles, nanowires, and nanotubes, because nanocomposites possess improved physical properties versus the unmodified polymer. In particular, a mixture of polymers and nanoparticles can form flexible nanocomposites [...]
