Acrylic pre-polymer was partially polymerized and the pre-polymer was cured with trimethylolpropane triacrylate (TMPTA) by UV irradiation. The effects of UV dose, acrylic acid contents, multi-functional monomer contents on the thermal diffusivity and adhesion properties of PSA were investigated. Thermal diffusivity increased with increasing UV dose up to 3000 mJ/㎠ and further increase was observed with the increase of TMPTA content. With increasing the UV dose, the thermal diffusivity was increased from 7.68 × 10-4 ㎠/s to 12.9 × 10-4 ㎠/s by introducing UV dose and TMPTA. An increase in the peel strength was also observed with the increase of UV dose and acrylic acid content. In acrylic adhesives with thermally conductive filler, the effect of filler (Carbon fiber or Al2O3) particles such as, their shape, contents and thermal conductivity and adhesion properties of thermal conductive adhesives were investigated. |
