    Abstract: The present invention relates to a method for preparing polymer-nanoparticles having a core-shell structure by uniformly coating a polymer on metal and inorganic particles, polymer-nanoparticles prepared thereby, and a polymer-nanoparticle composite comprising the same, and more specifically, a method for preparing polymer-nanoparticles having a core-shell structure by uniformly coating a polymer on metal and inorganic particles, polymer-nanoparticles prepared thereby, and a polymer-nanoparticle composite including the same, wherein when forming a polymer coating layer on surfaces of particles that are not subjected to separate surface treatment, excessive polymers uncoated on nanoparticles are easily removed by adding to an ionic liquid or an apolar solvent so that the polymer coating layer is formed with a nanometer-scale uniform thickness and a dense coating density, thereby showing excellent dispersibility in a polymer matrix.

    Abstract: The present disclosure relates to a polyamide-based polymer composition with superior fluidity and a polyamide-based composite material with superior mechanical strength prepared therefrom. More specifically, it relates to a polyamide-based polymer composition containing 0.1-5 parts by weight of dicyclohexylmethane bisdecanoamide, which is a cyclic compound, as a fluidity control agent based on 100 parts by weight of a mixture consisting of 20-90 wt % of a polyamide-based resin and 10-80 wt % of a reinforcing fiber, a polyamide-based composite material prepared using the same, and a method for preparing the same. The polymer composition according to the present disclosure, wherein dicyclohexylmethane bisdecanoamide is used as a fluidity control agent, provides an effect of reducing friction between a molten resin and a processing machine and greatly reducing torque by effectively dispersing a reinforcing fiber in a polyamide-based resin. Also, the polymer composition according to the present disclosure may be usefully used in compounding, extrusion molding and injection molding of polyamide-based engineering plastics containing reinforcing fibers at high contents. In addition, according to the present disclosure, the addition of the fluidity control agent greatly improves flowability during processing. Therefore, a polyamide-based composite material with superior mechanical strength can be prepared under relatively mild conditions because uniform mixing of the reinforcing fiber and the polymer resin is induced.
