Preparation of cassava starch grafted with polystyrene by suspension polymerization.
Cassava starch grafted with polystyrene (PS-g-starch) copolymer was synthesized via free-radical polymerization of styrene by using suspension polymerization technique. Potassium persulfate (PPS) was used as an initiator and water was used as a medium. The graft copolymer was characterized by Fourier transform infrared spectroscopy, differential scanning calorimetry, thermal gravimetric analysi...
متن کاملPreparation of Silver - Coated Polystyrene Composite Particles
We report a feasible approach to the preparation of monodispersed metal-shell composite microspheres based on a combination of surface reaction and surface seeding techniques. The method was implemented for coating polystyrene (PS) spheres with silver shell having a variable thickness by controlling the amount of reagents in the reaction procedure. These composite spherical particles in dimensi...

Hybrids of Polystyrene-b-Poly(ethylene-ran-butylene)-b- Polystyrene Reinforced by Electrospun Polyimide/ Carbon Nanotube Nanofibers: Preparation and Properties
Using electrospinning technique, well-aligned poly(azo-ether-imide) (PAEI) nano-fibers and PAEI/multiwalled carbon nanotube (MWCNT) nano-fibers were developed in this effort. Afterwards, polystyrene-b-poly (ethylene-ran-butylene)-b-polystyrene (SEBS) and polyimide-based nano-fiber films were casted. The as-prepared electrospun nanofibers acted as homogeneous reinforcement to enhance the tensile...
