A polymer composition for coating expanded polystyrene (EPS) is provided, the polymer composition includes a mixture of at least one of polyurea, polyurethane, silicon elastomer, and combination thereof in a predefined ratio. The polymer composition imparts desired properties such as high impact and abrasion resistance, elongation strength, and anti-static property along with flexural strength to the EPS. The present invention also provides the process for coating the polymer composition onto the EPS. The matrix coating process provides much stronger bonding due to overlap of coating of the polymer composition on the sides of the EPS and reduces the wastage of the polymer composition during the coating of the EPS. The present invention also provides the EPS coated with the polymer composition. The EPS coated with the polymer composition possesses the properties such as high impact resistance, abrasion resistance, elongation strength, flexural strength, and anti-static property.

The present disclosure relates to a perovskite light-emitting composition, and a method for preparing the same. The method for producing the perovskite light-emitting composition of the present disclosure includes an organic siloxane solvent having very high hydrophobicity and low surface tension as a synthesis solvent, thereby having a large surface tension difference from the perovskite light-emitting particles containing an organic ligand. Through these properties, a dense organic ligand can be attached to the surface of the perovskite nanoparticles, and perovskite light-emitting particles having a high ligand density can be prepared. Accordingly, the perovskite light-emitting particles prepared by the method of the present disclosure have improved dispersion stability, light-emitting properties and long-term storage stability.
