本文介紹了使用電紡絲(ES)設計和製造纖維素奈米結晶(CNC)奈米纖維複合材料。兩個主要研究目標是聚合物複合材料的開發以及圖案化奈米結晶複合 纖維的製造。目前，奈米纖維或複合奈米纖維由一種均勻的被動或活性化高分子 材料製成。目前還沒有關於通過在特殊可控制模式下，利用電磁手段激活電磁特 性的複合奈米纖維的研究。為了實現可控制特別圖案化的奈米纖維，現有的電紡 絲系統被特別修改或增強。在通過靜電紡絲時，在材料製備的後處理過程中摻入 不同功能性材料。這些第二相類的可以包括電介質，感測電和磁的奈米顆粒或聚 合物，全部由纖維素奈米結晶增強機械性質。這項研究的結果是實現對奈米纖維 形態的全面控制並生成可控制特殊形狀複合奈米纖維。

The thesis presents the design and fabrication of cellulose nanocrystal (CNC) nano-fiber composite using electro-spinning (ES). The two major research goals are the development of CNC polymer composites and the fabrication of patterned CNC composite nanofibers. Currently, nanofibers or composite nanofibers are made of one uniform passive or active material. There is no report of composite nanofibers with electromagnetic properties activated in controlled spatial patterns by electromagnetic means. To achieve the controlled spatial patterned nanofibers, existing ES system is specially modified or augmented. The functional materials are made by incorporating secondary phases either during electrospinning or in post-processing. These secondary phases may include dielectric, electrically and magnetically activated nanoparticles or polymers, all mechanically reinforced by CNCs. The outcome of this research is to achieve full control of nano-fiber morphology and generate controlled spatial patterned composite nanofibers.
