  • Poly(vinyl alcohol) / cellulose nanocomposite barrier films

    Creator:
    Paralikar, Shweta
    Abstract:
    There is a continual interest in developing robust, flexible, durable, lightweight, waterborne polymer barrier coatings which are increasingly resistant towards both chemical warfare agents as well as an ever growing number of toxic industrial chemicals. In this study, barrier films were prepared with poly(vinyl alcohol) (PVOH) and varying amounts of...

  • Improved interfacial adhesion in wood-plastic composites : Development of new compatibilizers

    Creator:
    Zhang, Cheng
    Abstract:
    In wood-plastic composites (WPCs) a compatibilizer is often used to improve the interfacial adhesion between the hydrophilic wood filler and the hydrophobic plastic matrix. At present, while the basic concepts of compatibilization are understood, the optimized chemical structures of an effective compatibilizer, including the ideal structures of the wood-binding domain...

  • Cellulose reinforced high density polyethylene

    Creator:
    Palaniyandi, Velmurugan
    Abstract:
    High density polyethylene (HDPE) is a ubiquitous material with versatile properties. It is produced and used in greater volume than any other thermoplastic. HDPE is often filled with a variety of materials for various applications. Glass fiber and wood flour are two common fillers for HDPE. Recently there has been...

  • Investigation of new compatibilizer systems for wood-polyethylene composites

    Creator:
    Geng, Yu
    Abstract:
    Wood-plastic composites (WPCs) are one of the fastest-growing sectors of the wood composites industry. However, the strengths of WPCs are typically low because of the poor interfacial adhesion between hydrophilic wood and hydrophobic thermoplastics. A compatibilizer that can form bridges between wood and plastics is required to give WPCs desirable...

  • Cellulose/polysulfone nanocomposites

    Creator:
    Noorani, Sweda
    Abstract:
    Microchannel devices are rapidly evolving process technology with a wide variety of applications. Microchannel devices hold the potential to transform many separation processes. One potential application for such microchannel devices is kidney dialysis. By reducing the size and cost of the device, this technology offers the potential to allow dialysis...

  • 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,...
