Problem statement: Polystyrene failed to provide any reactive functionality of surface hydrophilicity that is capable of binding proteins. It is known that polystyrene must be chemically modified to make its surface amenable to covalent crosslinking with protein. Approach: The aim of this study was to investigate the effects of UV/ozone treatment on gelatin coating. The surfaces of microsize po...

utilizing polymeric materials for damping mechanical waves is of great importance in various fields of applications such as military camouflage, prevention of structural vibrational energy transfer, and noise attenuation. this ability originates from segmental dynamics of chain-like polymer molecules. damping properties of styrene-butadiene rubbercontaining 10 wt% of monosize polystyrene partic...

Plain reservoirs in arid areas usually have a shallow water depth, a large surface area, and severe evaporative water-loss. To lessen the water loss, a polystyrene board coverage technique was used. This paper represents a demonstrative application study of the polystyrene board coverage technique in the Daquangou Plain Reservoir in the city of Shihezi, Xinjiang. Six different polystyrene board...

Flame retardancy is the property that highly demanded when it comes to deal with plastics in different industries. In this research general purpose polystyrene (GPPS) and modified sepiolite clay are melt blended together fabricate flame retardant nanocomposites. Structural analysis were performed help of Fourier transform infrared spectroscopy (FTIR) X-ray diffraction (XRD) techniques. Morpholo...

Specific three-point hydrogen bonding between diamidopyridine (DAP) and thymine (Thy) was employed to reversibly anchor "brush-like" Tri-DAP end-functionalized polystyrene onto Thy-modified silica surfaces.

The formation of membranes from two systems has been studied. In the system polyurethanedimethylformamide-water, the mechanism for the formation of the sponge-like structure proves to be a liquid-liquid phase separation with nucleation and growth of the diluted phase. This mechanism has been confirmed for the system modified polystyrene-polyisoprene-polystyrene/ o-dichlorobenzene/(methanol-wate...

A polystyrene coated quartz crystal nanobalance (QCN) sensor was developed for use in the determination of a number of linear short-chain aliphatic aldehyde and ketone vapors contained in air. The quartz crystal was modified by a thin-layer coating of a commercial grade general purpose polystyrene (GPPS) from Tabriz petrochemical company using a solution casting method. Determination was based ...

Crosslinked poly(acrylic acid)-b-polystyrene polymersomes were successfully employed to form a water-in-oil Pickering emulsion and enabled an easy and reversible disassembly due to the pH sensitivity. The side of the polymersomes exposed to the water phase was selectively modified with metal nanoparticles, allowing facile formation of anisotropically modified Janus polymersomes.
