英文摘要	In this experiment, pure pbsu fibers, pbsu/12.5% beta-casio3, and pbsu/25% beta-casio3 composite fibers were fabricated by electrospinning. in order to investigate the effects of surface modification of beta-casio3 on composite fibers, beta-casio3 nanowires were surface esterified using dodecyl alcohol. sem micrographs showed that composite materials with modified beta-casio3 have homogeneous fibrous structures similar as that of pure pbsu fibers, while the fibers containing unmodified beta-casio3 were inhomogeneous and much larger in diameter, and also junctions where beta-casio3 agglomerated could be found. mechanical testing showed that with the addition of unmodified beta-casio3 into pbsu matrix, the tensile strength of fibrous materials decreased obviously, and the decrease degree increased with increased beta-casio3 content. however, the tensile stresses of composite materials after surface modification of beta-casio3 turned back and increased about 40% compared to those containing unmodified beta-casio3. all of these results suggested surface modification of beta-casio3 was an effective approach to obtain composite fibrous materials with better morphologies and enhanced mechanical properties, and this method is supposed to be feasible in other fibrous material systems.
