| 제목 | Improved thermal conductivity of stretchable PVA/h-BN composites |
| 초록 | As an efficient heat releasing material from the inside of electric and electronic devices is getting important for both their drastic miniaturization and high performance, the use of polymers and polymer composites as thermally conductive materials is increasing for weight loss, low cost, facile processibility and high performance. In this work, we demonstrate that enhanced thermal conductivity of polyvinyl alcohol (PVA) composites using hexagonal boron nitride (h-BN). For better dispersion without additional surface modification of h-BN, ultra-sonication with high intensity ultrasonic probe was used to prepare the hybrid solution. A custom-made film stretching apparatus was used to determine the stretching properties. Thermal conductivities of cast films and stretched films were determined using laser flash method. |
