172. Enhanced thermal diffusion in the vertical direction of flexible polyimide composite films with magnetically alignable h-BN platelets viaferrofluids hybridization

Abstract

A facile approach is proposed to improve the anisotropic heat conduction of polyimide composite films containing hexagonal boron nitride (h-BN), thermally conductive filler with high anisotropy, viasurface hybridization with ferrofluids as magnetic carrier source. The surfaces of the h-BNs were decorated with Fe3O4particles to control their alignment using magnetic field. The h-BNs with hydroxyl groups (f-BN) were mixed with ferrofluids and heated to 130 °C with stirring. A considerable amount of Fe3O4nanoparticles was attached to the surface of f-BNs, named mf-BNs. Flexible polyimide (PI) composite films were prepared by adding mf-BNs at 1–30 wt.% to investigate the anisotropic alignment of mf-BNs under magnetic field. The thru-plane thermal conductivity of the PI composite film with vertically aligned mf-BN of 30 wt.% is 6 times higher than that of the neat PI film, as increased from 0.212 to 1.246 W/m∙K. This result is attributed to the anisotropic h-BN particles coated with the magnetic fluid arranged within the PI matrix in the vertical direction by using a neodymium magnet with less than 150 mT. This can solve the thermal issues of next-generation electronics by speeding the vertical heat transfer, which can greatly contribute to the improvement of the device reliability.

Abstract

A theory is described, for the short-circuit 1/[integral] noise currents in semiconductor devices with one-dimensional geometry. The theory uses the noise-current-density equation with the 1/[integral] noise-source term, based on the Hooge's empirical 1/[integral] noise relation.

Abstract

This study evaluated the feasibility of recovering and recycling nitrogen (N) and phosphorus (P) from livestock excreta as struvite ( $MgNH_4PO_4{\cdot}6H_2O$ ) in South Korea. Our experimental results showed that struvite precipitation was a very effective way to recover N and P from livestock ex...
