POLYMER COMPOSITION FOR LED COOLING RADIATORS AND METHOD OF ITS OBTAINMENT

摘要

FIELD: electricity.SUBSTANCE: composition includes a polypropylene polymer matrix and mix of carbon fibre and carbon nanotubes with dispersion under 100 nm and 9:1 weight ratio of carbon fibre and carbon nanotubes in the mix. To obtain polymer composition, polypropylene polymer matrix solution in organic solvent is mixed with the mix of carbon fibre and carbon nanotubes in ultrasonic cavitation processing mode. Afterwards, obtained sol is precipitated in ice acetone with further flushing and drying.EFFECT: improved heat conductivity properties for efficient heat removal and improvement of physical, mechanical, and optical parameters of LEDs.2 cl, 4 dwg
