    Abstract: The present disclosure relates to an elastomer-conductive filler composite for a flexible electronic material having improved dielectric property and elastic modulus, and a method for preparing same. The elastomer-conductive filler composite according to the embodiments of the present disclosure solves the problem of the existing insulator-conductor composite that elastic modulus increases and adhesion property decreases with the increase in dielectric constant as the content of the conductive filler in elastomer increases. In particular, since the composite has a high dielectric constant in spite of a low content of the conductive filler and since the elastic modulus increased because of the conductive filler can be recovered by the plasticizer, the sensitivity of a sensor can be improved. Accordingly, it can be usefully used for flexible substrates and flexible touch panels or touchscreens, touchpads, etc. including them.

    Abstract: Disclosed is an elastomer-conductive filler composite with improved dielectric properties. The composite includes conductive fillers and an ionic liquid dispersing the conductive fillers. The ionic liquid is used as a dispersant to effectively enhance the dispersion of the conductive fillers, achieving a high dielectric constant and a low dielectric loss of the composite without deteriorating the physical properties of the conductive fillers. The use of the ionic liquid can reduce the number of processing steps and the presence of the conductive fillers at a low concentration in the composite can minimize deterioration of the physical properties of the elastomer. Further disclosed is a method for producing the composite.

    Abstract: The present disclosure relates to a stretchable electrode, a method for preparing the same and a stretchable battery including the stretchable electrode. The stretchable electrode of the present disclosure, which is prepared by crosslinking a hydroxyl-functionalized fluorine-based polymer binder physically using a ketone-based solvent or chemically with a crosslinking agent, has superior stretchability, has improved interfacial adhesivity to an active material through Fenton's oxidation, exhibits improved stability under various mechanical deformations of the electrode such as stretching, etc. and can uniformly maintain the electrical conductivity, battery capacity and charge-discharge performance of the electrode.
    In addition, the stretchable battery of the present disclosure, which includes the stretchable electrode, a stretchable current collector, a stretchable separator and a stretchable encapsulant, has improved stretchability and superior battery stability under various deformations due to high degree of freedom of structures and materials. In addition, the stretchable battery of the present disclosure can be prepared as a fiber battery by printing an electrode and a current collector sequentially on both sides of a stretchable fabric, which can be worn, e.g., around sleeves due to superior stretchability and high structural degree of freedom and retains high battery performance and mechanical stability even under mechanical deformation. Therefore, it can be applied to a mobile display for a health monitoring system or a smartwatch.
