The present invention relates to a polyvinyl-based compound, which maximizes self-healing ability by introducing various functional molecules into a brush of a polyvinyl-based resin, a preparation method thereof, and a polymer coating film produced therefrom.

Self-healing functional polyvinvyl-based compound and preparation method thereof

The present invention is a vacuum evaporation heating assembly for heating a carrier, in which an evaporation material is filled, in a vacuum evaporation process, the vacuum evaporation heating assembly comprising: a carrier container in which the carrier is installed; and an electrode connector which extends in both directions of the carrier container to be connected to an electrode. At least one of the carrier container and the electrode connector is a plate-shaped member. The vacuum evaporation heating assembly can securely hold the carrier, in which the evaporation material is filled, and can vaporize the evaporation material in a specialized direction, thereby uniformly and efficiently evaporating the evaporation material with a small number of carriers.
