제목 Heat radiating polyurethane composite using modified boron nitride to enhance flame retardancy
초록 As household appliances such as mobile phones, laptops, and automobiles are highly integrated and miniaturized, a large amount of heat is generated in the driving time. And it is very important to release the heat to the outside, because this heat degrades the performance of device, causes malfunctions, and has a large impact on durability. Then the social interest and market size of the heat radiating materials are increasing every year. In this study, polyurethane(PU)/modified boron nitride(m-BN) composites were prepared for heat-radiating film. PU is flexible and has excellent tensile strength, also physical property can be easily controlled through the molecular design. However, owing to the PU is unstable in heat and easy to burn, its use is restricted in the field which is a risk of fire due to heat, leakage, spark, etc. Then BN was modified with organo-phosphorus incorporated silane coupling agent to solve the combustion problem.
