Abstract
- The existence of an oxide (B 2 O 3) film covering the boron (B) surface affects its energy release during combustion. Fluoropolymer modification can help to solve the problem. The electrospinning and solvent anti-solvent methods were utilized to modify boron nanoparticles (n-B) using polyvinylidene fluoride (PVDF) as a modified material, which can effectively coat B particles. The thermal behavior, combustion characteristics, and condensed combustion products of the B/PVDF composites were investigated and evaluated. The agglomeration size of B particles can be decreased while its reaction heat and combustion intensity are increased. Significantly, the combustion performance of the B/PVDF composites prepared by the electrospinning method is better than that of the B/PVDF composite prepared by the solvent anti-solvent method. These results can be helpful in promoting the practical application of B. [ABSTRACT FROM AUTHOR]
