General description

Polystyrene is a high molecular weight synthetic polymer made from the polymerization of styrene. It is durable, thermoplastic, and hydrophobic in nature.

Application

Polystyrene(PS) can be used as a precursor to synthesize dye-doped fluorescent PS nanoparticles, which can be applied in the field of optical microscopy, cell tracking, and optical sensors.

It can be used to stabilize the perovskite component by forming PS-capped perovskite grains. This PS coverage can suppress the organic component evaporation, and water corrosion and promotes crystal self-healing of perovskite films.

Due to its optical clarity, low production cost, and ease ofmanufacture, it is widely used as a fundamental substrate for in vitrocell culture.

The differently sulfonated styrene-divinylbenzene cross-linked copolymer cationic exchange resins were prepared by oil-in-water polymerization and varied degrees of sulfonation. Several characteristics of the obtained resins were evaluated, i.e., Fourier transform infrared spectra, the ion-exchange capacity, microscopic morphology, size, and swelling.
