在工業發展迅速的時代下，大量的使用石油及煤碳做為能源及工業原料，造成工廠排放的廢氣以及交通運輸等汙染，而將許多有害的氣體與塵埃大量的送進了空氣中，這些有害的氣體與塵埃，不僅危害人體健康，更嚴重影響了生態環境。近年來，空氣污染對於人類健康以及環境污染問題日益嚴重，而當中最為嚴重的為PM2.5，為了對付細懸浮微粒，空氣過濾材會將孔徑縮小，但卻往往造成空氣流通的問題，導致在使用上的不方便；且在近幾年，為了更加提升過濾材料之過濾能力，除了過濾材料基材的研究之外，更致力於過濾層之改質，像是殺菌濾材以及帶電濾材，藉此提升過濾懸浮微粒之能力，還能增加濾材額外之功能，而非只有單純的過濾功能而已。
本研究為利用靜電紡絲技術結合了微波水熱法製備出二氧化鈦/鈦酸鋇/聚丙烯腈奈米纖維濾材，因此本研究之實驗方法以及實驗結果與討論分為兩大部分，第一部分為利用微波水熱法製備二氧化鈦球珠（TiO2 beads）以及鈦酸鋇奈米顆粒（BaTiO3 nanoparticles），透過水熱法之溫度來控制顆粒尺寸以及結晶性等。第二部分為利用靜電紡絲技術製備奈米纖維，以聚丙烯腈作為濾材之基底，在二氧化鈦之部分，分別以不同重量百分比之商用二氧化鈦（P25）以及二氧化鈦球珠加入，發現加入商用二氧化鈦對於光降解以及抗菌方面有良好之結果，而二氧化鈦球珠則對於空氣過濾有較佳之效果，主要原因為二氧化鈦球珠在電容量之表現優於商用二氧化鈦，因此能以靜電吸引較多之微粒；而在鈦酸鋇奈米顆粒，分別也以不同之重量百分比加入，發現鈦酸鋇奈米顆粒對於空氣過濾之效果也有所提升，主要原因為靜電吸引所造成。綜合以上之敘述，了解二氧化鈦（商用二氧化鈦以及二氧化鈦球珠）以及鈦酸鋇之加入對於濾材的影響，因此製備出具有高過濾效能、低空氣阻力以及抗菌等多功能PM2.5過濾用之不織布。

Commercial TiO2(P25)/PAN electrospun nanofibers, TiO2 beads/PAN electrospun nanofibers, and Commercial TiO2(P25)/ TiO2 beads/PAN electrospun nanofibers were prepared by electrospinning technique. This study will through add different concentration of TiO2 (P25 and TiO2 beads) to understand whether P25 and TiO2 beads have influence on surface morphology, filtration efficiency, and photodegradation efficiency.
SEM analysis showed that commercial commercial TiO2(P25) and TiO2 beads were existed in nanofibers, we can understand the photocatalytic efficiency of nanofibers and prove the antibacterial results through photodegradation analysis, and anti-bacteria ability was analyzed by ISO 20743.
Selected samples were evaluated for filtering efficiency using air filtration equirment and the removal efficiency was calculated by comparing the PM particle number concentration before and after filtration.
