  • Gelatin-Graphene Nanocomposites with Ultralow Electrical Percolation Threshold
    Advanced Materials, 2016
    Co-Authors: Hoda Nassira, Nader Taheri Qazvini, Stephan Handschin, Antoni Sánchez-ferrer, Jozef Adamcik, Hossein Mahdavi, Raffaele Mezzenga
    Abstract:

    Gelatin-graphene conductive biopolymer nanocomposites (CPCs) with ultralow percolation threshold are designed by reducing in situ graphene oxide nanosheets with ascorbic acid and suppressing the aggregation of the graphene nanosheets. The resulting conductive nanocomposites show a record-low electrical percolation threshold of 3.3 × 10(-2) vol%, which arises from the Homogeneous Dispersion of the graphene nanosheets within the gelatin matrix.

  • Methodology for Homogeneous Dispersion of single-walled carbon nanotubes by physical modification
    Polymer Journal, 2008
    Co-Authors: Tsuyohiko Fujigaya, Naotoshi Nakashima
    Abstract:

    Science and technology on carbon nanotubes (CNTs) are an expanding field aiming at ascertaining their intrinsic properties and taking advantage of their inviting possibilities. Dealing with CNTs has faced the problem of insolubility in both organic and inorganic solvents due to the strong interaction therein. Here we review the recent progress as well as our approaches to the solubilization of CNTs based on a physical modification method. Especially, the review focuses on the ‘individual’ solubilization of pristine CNTs in solvents. Individual solubilization of CNTs is imperative in many research programs such as chemical modification of CNTs via organic reactions, characterization of CNTs chiral indices as well as separation of these mixtures, preparation of composites with polymers, fabrication of CNTs-based nanoelectronics devices and so forth.

  • Silver-plated carbon nanotubes for silver/conducting polymer composites
    Nanotechnology, 2008
    Co-Authors: Daewoo Suh, Young-jin Kim, Eung-suek Lee, Jee Soo Mok, Jae-boong Choi, Seunghyun Baik
    Abstract:

    Carbon nanotubes (CNTs) have advantages as conductive fillers due to their large aspect ratio and excellent conductivity. In this study, a novel silver/conducting polymer composite was developed by the incorporation of silver-plated CNTs. It is important to achieve a Homogeneous Dispersion of nanotubes and to improve the interfacial bonding to utilize the excellent properties of reinforcements in the matrix material. The Homogeneous Dispersion of nanotubes was achieved by an acid treatment process, and the interfacial contact was improved by electroless silver plating around nanotubes. The resistivity of the silver/conducting polymer composite was decreased by 83% by the addition of silver-plated single-walled carbon nanotubes. Conductive bumps were also screen-printed to demonstrate the capability of the composite as electrical interconnects for multi-layer printed circuit boards.

  • 2D nanosheet-constructed hybrid nanofillers for polymer nanocomposites with synergistic Dispersion and function
    APL Materials, 2019
    Co-Authors: Liu Ying, Yufeng Wang, Chao Zhang, Tianxi Liu
    Abstract:

    Polymer nanocomposites (PNCs) are new-emerging multicomponent polymer composites consisting of a polymer matrix and well dispersed nanofillers. Nanofillers can be divided into one-dimensional, two-dimensional (2D), or three-dimensional nanoparticles according to their dimensions. Due to their outstanding physical properties, the achievement of Homogeneous Dispersion of 2D nanofillers in the polymer matrix plays a decisive role in the fabrication of high-performance and multifunctional PNCs. The construction of 2D nanosheets into hybrid nanofillers provides a new idea for achieving Homogeneous Dispersion of 2D nanofillers in the polymer matrix. In this review, recent developments on the design strategies and controllable preparation methods of hybrid nanofillers containing 2D nanosheets are summarized. The preparation, structure, and physical properties of PNCs with 2D nanosheet-constructed hybrid nanofillers are discussed in detail. Finally, challenges and future prospects of PNCs with 2D nanosheet-constructed hybrid nanofillers are highlighted.Polymer nanocomposites (PNCs) are new-emerging multicomponent polymer composites consisting of a polymer matrix and well dispersed nanofillers.

  • carbon nanotubes reinforced nylon 6 composite prepared by simple melt compounding
    Macromolecules, 2004
    Co-Authors: Wei De Zhang, Lu Shen, In Yee Phang, Tianxi Liu
    Abstract:

    The challengesfor developing high-performance CNTs/polymer nano-composites are (i) Homogeneous Dispersion of CNTs inthe polymeric matrix and (ii) strong interfacial interac-tions so as to effect efficient load transfer from thepolymeric matrix to the CNTs. Without chemicallybonding, load transfer between the CNTs and thematrix mainly comes from electrostatic and van derWaals interactions.
