A method for preparing a super-lubricative multi-layer composite fullerene-like carbon layer/graphene-like boron nitride thin film is provided. A substrate is ultrasonically cleaned in absolute ethyl alcohol and acetone sequentially for 15 min. The substrate is cleaned by argon plasma bombardment for 15 min. A fullerene-like carbon layer A having an onion-like structure is prepared by high-vacuum medium-frequency magnetron sputtering for 30 s. A graphene-like boron nitride layer B is prepared by high-vacuum medium-frequency magnetron sputtering and coating device to sputter the elemental boron target for 30 s. Steps (3) and (4) are repeated 80 times to overlay the fullerene-like carbon layer A and the graphene-like boron nitride layer B in an alternate way. The super-lubricative multi-layer composite fullerene-like carbon layer/graphene-like boron nitride thin film has a large load capacity, and excellent wear resistance, high temperature resistance and super lubrication.

A flexible boron nitride nanoribbon aerogel has an interconnected three-dimensional porous network structure which is formed by mutually twining and contacting boron nitride nanoribbons and consists of macropores having a pore diameter of more than 50 nm, mesopores having a pore diameter of 2-50 nm and micropores having a pore diameter of less than 2 nm. The preparation method of the flexible boron nitride nanoribbon aerogel includes the following steps: performing high-temperature dissolution on boric acid and a nitrogen-containing precursor to form a transparent precursor solution, preparing the transparent precursor solution into precursor hydrogel, subsequently drying and performing high-temperature pyrolysis to obtain the flexible boron nitride nanoribbon aerogel. The boron nitride nanoribbon aerogel has excellent flexibility and resilience and can withstand different forms of loads from the outside within a wide temperature range.

The boron nitride precursor material subjected to lamp ablation may include amorphous boron nitride, hexagonal boron nitride, cubic boron nitride, wurtzite boron nitride or a combination of two or more thereof.

High quality, catalyst-free boron nitride nanotubes (BNNTs) that are long, flexible, have few wall molecules and few defects in the crystalline structure, can be efficiently produced by a process driven primarily by Direct Induction. Secondary Direct Induction coils, Direct Current heaters, lasers, and electric arcs can provide additional heating to tailor the processes and enhance the quality of the BNNTs while reducing impurities. Heating the initial boron feed stock to temperatures causing it to act as an electrical conductor can be achieved by including refractory metals in the initial boron feed stock, and providing additional heat via lasers or electric arcs. Direct Induction processes may be energy efficient and sustainable for indefinite period of time. Careful heat and gas flow profile management may be used to enhance production of high quality BNNT at significant production rates.
