  • The Use of Various Morphologies of Nanocellulose as Life Long Anodes of Sodium Ion Batteries

    Creator:
    Schardt, Jenna
    Abstract:
    Sodium-ion batteries (SIBs) require the use of a highly reversible anode. To form this anode carbon nanofibers and nanocrystals are derived from cellulose nanofibers, cellulose nanocrystals, and bacterial nanocellulose. The primary structure of the cellulose nanofibers is maintained when carbonized allowing for high surface area in the structure. The carbon...

  • Photoinitiated grafting of PMMA onto cellulose nanocrystals to improve nanocomposite reinforcement-matrix interface

    Creator:
    Mirashrafi, Suzanne
    Abstract:
    Cellulose nanocrystals (CNCs) are extremely abundant, biodegradable and light weight nanoparticles that have the potential to contribute in many fields including packaging, construction, solar cells and automotive. With the increasing interest in nanotechnology and nanocomposites, CNCs could provide a renewable, optically transparent and strong alternative to other nano-scale reinforcement phases....

  • Study of Interphase in Polylactic Acid and Cellulose Nanocrystal Composite Films

    Creator:
    Rao, Pratish Ramesh
    Abstract:
    Polylactic acid (PLA), a renewable material, is used widely in a variety of commercial and specialty applications. However, certain limitations such as high temperature stability and brittleness limit its applicability. This problem is addressed by reinforcing PLA with a variety of materials but the process gives rise to different issues...

  • Ionic Cross-linked Cellulose Nanocrystals Composites of Poly(vinyl acetate)

    Creator:
    Chan, Han Ling
    Abstract:
    Understanding the effect on the materials mechanical properties from the perspective of interfacial interaction between the filler and the polymer matrix has become an important criterion in polymer nanocomposites field. Cellulose nanocrystals (CNCs) are renewable materials that can be extracted from natural sources, such as wood, cotton, and tunicates. In...

  • Transient electric birefringence for the characterization of cellulose nanocrystals and tobacco mosaic virus

    Creator:
    Taylor, Melissa J.
    Abstract:
    The development of a transient electric birefringence (TEB) apparatus for macroparticle characterization is herein discussed. The experimental difficulties encountered were related largely to poor data resolution. Misalignment and strain birefringence in optical components further complicated results. Improved data digitization methods were developed, and precise mathematical models were derived in order...

  • Nanocomposites incorporating cellulose nanocrystals with potential applications in lithium ion batteries

    Creator:
    Kelley, Jeremiah (Jeremiah Joseph)
    Abstract:
    Cellulose nanocrystals (CNCs) have received considerable attention over the last ten years because CNCs can be produced from renewable materials such as straw, wood, cotton, and sea animals (tunicates). CNCs are slender rods with high aspect ratios (10-100) and the final dimensions of the CNCs depend on the starting material....

  • Interfacial shear strength of wood-plastic composites

    Creator:
    Rogers, James F.
    Abstract:
    This study examined the relationship of interfacial shear strength (IFSS) and bending strength (MOR) of several different wood-plastic composites (WPC's). Plastics utilized were high-density polyethylene (HDPE) and polypropylene (PP). Pine and oak were used as the wood species. Compatibilizers used included maleicanhydride polyethylene (MAPE), polymeric methylene diphenyl diisocyanate (PMDI), KymeneTM,...
