摘要:
Disclosed herein is a crosslinkable thermoset monomer. The crosslinkable thermoset monomer has acetylene groups as crosslinking groups introduced at both ends of the backbone. Also disclosed herein is a composition for producing a printed circuit board which comprises the crosslinkable thermoset monomer. The composition exhibits excellent mechanical and thermal properties. Therefore, the composition can be used as a material for next-generation boards that are becoming lighter in weight and smaller in size and thickness. Also disclosed herein is a printed circuit board using the composition.

A paste composition comprises a dye containing a novel oligomeric compound with improved dispersion performance. The oligomeric compound comprises a tail structure consisting of hydrophilic and hydrophobic blocks and an amine or imidazole head structure. The paste composition can be used to prepare a semiconductor electrode of a solar cell. A semiconductor electrode produced using the paste composition and a solar cell fabricated using the semiconductor electrode exhibit greatly improved power conversion efficiency and superior processability.

Disclosed is a polymeric surfactant for high dielectric polymer composites, a method of preparing the same, and a high dielectric polymer composite including the same. The polymeric surfactant for high dielectric polymer composites, which includes a head portion having high affinity for a conductive material and a tail portion having high affinity for a polymer resin, forms a passivation layer surrounding the conductive material in the high dielectric polymer composite including the polymeric surfactant, thus ensuring and controlling a high dielectric constant.

Disclosed are a novel dye, having a dispersant functional group to simultaneously exhibit a dye function and a dispersant function, and a dye-sensitized solar cell including the same. According to this invention, the dye may simultaneously manifest a dye function for absorbing light, made possible by being adsorbed on the entire surface of metal oxide particles, to thus produce excited electrons which are then transferred into a conduction band of metal oxide, and a dispersant function for preventing the agglomeration of the particles to thus improve the uniformity of the metal oxide particles in a paste and film density.
