【 摘 要 】

tsCarbon fiber (CF) scaffolds with horizontally aligned, diagonally aligned and vertically aligned structure were fabricated via magnetic field-assisted Tetris-style stacking and carbonization process.The obtained CF scaffolds/ polydimethylsiloxane composites showed ultrahigh thermal conductivity (above 40 W m−1 K−1) in the fiber alignment direction.Fibers with different alignment direction can be combined by multiple stacking and carbonization process, allowing for the efficient heat transfer along customized paths.
