In Part Two, Chapter 4 describes a general fabrication-characterization route of electrospinning PLA poly(s-caprolactone) (PCL)/HNT composite fibers. The effects of HNTs with or without the modifier 3-aminopropyltriethoxysilane on fiber diameter, morphological structure, thermal properties, crystalline stmctures, and degree of crys-talhnity, as well as the intermolecular interaction of electrospun nanocomposite fibers, are thoroughly studied to provide the appropriate guidance to the controlled drug release associated with fibrous structures. Chapter 5 deals with the synthesis and characterization of CNT hybrid fillers via chemical vapor deposition (CVD) technique for polymer nanocomposites. Optimized synthesis parameters are presented and comparative studies are also conducted between chemical hybrid-filled and physical hybrid-fiUed polymer nanocomposites in terms of their typical applications.

Kim et al. (2(X)5) employed PLA electrospun fibers as a nanocomposite material to investigate their role in bone regeneration. The authors have used HA as nanofiller components to synthesize the nanocomposite scaffolds. The scaffolds supported enhanced attachment and proliferation of osteoblasts, hi another study, Jose et al. (2009) employed aligned PLGA nanofibers along with HA to fabricate nanocomposite scaffolds. The authors showed that the nanocomposites enhanced scaffold mechanical properties as compared to the PLGA nanofibers. [Pg.7]

In order to prepare PLA nanocomposites with highly dispersed cellulose nanocrystals and porous PLA-based scaffolds with enhanced mechanical properties and thermal stability, CNCs have been incorporated into PLA fibres by electrospinning method. Fibrous biocomposite mats consisting of PLA and CNCs have been electrospun from solvent or solvent mixtures such as l,l,l,3,3,3-hexafluoro-2-propanol (HFP), DMF/chloro-form and DMF/tetrahydrofuran (THF). The electrospun PLA/CNCs bionanocomposites have demonstrated rapid in vitro biodegradability and cytocompatible properties, and could be potentially suitable in tissue engineering. ... [Pg.231]

This chapter aims to examine the effect of HNTs with or without modifier 3-aminopropyltriethoxysilane (ASP) on fiber diameter, morphological structure, thermal properties, crystalline structures, and degree of crystallinity, as well as intermolec-ular interaction of electrospun PLA PCL/HNT nanocomposite fibers in order to provide the appropriate guidance to controlled drug release associated with fibrous stmctures in the fumre.

Electrospun fibers have also been researched for cartilage regeneration procedures. Thorvaldsson et al. (2(X)8) used a combination of micro- and nanofibers to create novel fiber structures. This enhanced the pore structure characteristics of the fabricated scaffold. The synthesized scaffold enhanced the human chondrocyte infiltration. Nanocomposites consisting of multiwalled carbon nanombes (MWCNTs) and PLA were fabricated using electrospinning. The nanocomposite material displayed enhanced mechanical properties and improved the chondrogenesis of MSCs (Holmes et al., 2013). [Pg.15]
