Homogeneous alumoxane-LCT-epoxy polymers and methods for making the same

1. A method of increasing the thermal conductivity of an electrically insulating epoxy material without compromising the electrical insulating properties of the material, the method comprising:

stirring an LCT-epoxy resin comprising a crystalline microstructure having a layered nature with an anhydriding agent at approximately 60° C. until a clear LCT-epoxy anhydride solution is formed;

after the solution is clear, adding a boehmite material into the clear solution and stirring at approximately 60° C., until the solution is again clear to form a uniform dissolution of the boehmite material substantially free of particle wetting and with essentially complete co-reactivity of the boehmite material with the LCT-epoxy anhydride; and

adding an accelerator and curing the solution;

the method effective to produce homogeneous alumoxane-LCT-epoxy-anhydride polymers that retain the layered nature of the LCT-epoxy resin and are substantially free of micro-void formation and that exhibit a dielectric strength of at least 1.2 kV/mil while at the same time exhibiting thermal conductivity of at least 0.50 W/mK in a transverse direction and at least 0.99 W/mK in a thickness direction in an environment of 25° C.

2. The method of claim 1 , further comprising dissolving zinc naphthenate into the solution as the accelerator.

3. A homogeneous alumoxane-LCT-epoxy anhydride polymer produced by the method of claim 1 and comprising a crystalline microstructure having a layered nature and exhibiting a dielectric strength of at least 1.2 kV/mil while at the same time exhibiting thermal conductivity of at least 0.50 W/mK in a direction transverse to layers of the microstructure and at least 0.99 W/mK in a thickness direction across the layers of the microstructure in an environment of 25° C.
