  • Magnetic Polymer Composite Particles: Design and Magnetorheology.
    Polymers, 2021
    Co-Authors: Kisuk Choi, Jae-do Nam, Hyoung Jin Choi
    Abstract:

    As a family of smart functional hybrid materials, magnetic Polymer Composite particles have attracted considerable attention owing to their outstanding magnetism, dispersion stability, and fine biocompatibility. This review covers their magnetorheological properties, namely, flow curve, yield stress, and viscoelastic behavior, along with their synthesis. Preparation methods and characteristics of different types of magnetic Composite particles are presented. Apart from the research progress in magnetic Polymer Composite synthesis, we also discuss prospects of this promising research field.

  • recent progress in smart Polymer Composite particles in electric and magnetic fields
    Polymer International, 2013
    Co-Authors: Ying Dan Liu, Hyoung Jin Choi
    Abstract:

    Electrorheological (ER) and magnetorheological (MR) fluids based on electro- and magneto-responsive particles, respectively, are smart suspensions with the ability to undergo phase transitions from a liquid-like to a solid-like state as a result of stimuli of an electric or magnetic field. The application of Polymer Composite materials rather than pure Polymeric or inorganic materials is aiming to solve the problems in the use of both ER and MR materials, such as low activity, physical and chemical stability, and production cost. Various fabrication methods of Polymer Composite materials with electro-activity or magneto-activity developed and effectively applied in this field to boost the wide commercialization of both ER and MR fluids are briefly reviewed in this perspective. © 2012 Society of Chemical Industry

  • Polymer Composite and nanoComposite dielectric materials for pulse power energy storage
    Materials, 2009
    Co-Authors: Peter Barber, Yogesh Anguchamy, Shushan Gong, Hongsheng Gao, Harry J. Ploehn, Shiva Balasubramanian, Arief Wibowo, Hans-conrad Zur Loye
    Abstract:

    This review summarizes the current state of Polymer Composites used as dielectric materials for energy storage. The particular focus is on materials: Polymers serving as the matrix, inorganic fillers used to increase the effective dielectric constant, and various recent investigations of functionalization of metal oxide fillers to improve compatibility with Polymers. We review the recent literature focused on the dielectric characterization of Composites, specifically the measurement of dielectric permittivity and breakdown field strength. Special attention is given to the analysis of the energy density of Polymer Composite materials and how the functionalization of the inorganic filler affects the energy density of Polymer Composite dielectric materials.

  • physical properties of Polymer Composite natural rubber glove waste polystyrene foam waste cellulose
    Industrial Crops and Products, 2012
    Co-Authors: Sa-ad Riyajan, Isara Intharit, Pramuan Tangboriboonrat
    Abstract:

    Abstract The Polymer Composite was prepared from the wastes of natural rubber glove (NRG) and polystyrene foam (PSF) blended with cellulose from sugar cane leaves via the laminate method. The NRG and PSF were firstly dispersed in toluene under continuous stirring. Then, maleic anhydride (MA) was added into the mixture. Effects of blend ratio and of MA content (0.5–15%, w/w) on physical properties of the Polymer Composite were investigated. The toluene resistance of the Polymer blend was improved after adding MA and cellulose. The highest toluene resistance was achieved when using 12% cellulose. The chemical reactions of MA with Polymer blend and with Composite were confirmed by ATR-FTIR. The hardness of the Polymer blend and Composite increased as a function of PSF. In addition, their impact strength increased with increasing NRG and cellulose contents.

  • Measuring Polymer Composite interfacial strength
    Composites Part B-engineering, 2014
    Co-Authors: I. Swentek, Jeffrey T. Wood
    Abstract:

    Abstract Polymer matrix Composites are seeing increased use in the automotive industry due to their significant potential for vehicle mass reduction, but are hampered by the lack of sufficient material models to predict their plastic deformation. Material models using fiber–matrix interfacial strength as an input show promise in predicting the inelastic mechanical properties. This study presents a new method to directly measure the interfacial shear and normal strengths via a model system. The lap-shear test is modified to measure the interfacial shear strength, while a modified tensile test is conducted to measure the interfacial normal strength. The degree of cure and the addition of silane coupling agents are introduced as independent variables to examine their effect on interfacial strengths. The experimental results for a glass/epoxy system are reported and are validated against traditional interfacial measurement tests. The lap shear test is a rapid, cost-effective tool to quantitatively measure the interfacial strength of a Polymer Composite system.

  • reinforcement of silicone rubber with raspberry like sio2 Polymer Composite particles
    Polymer International, 2015
    Co-Authors: Xinping Zhang, Yinyan Guan, Yunfeng Zhao, Zhijie Zhang, Dong Qiu
    Abstract:

    Raspberry-like SiO2@Polymer Composite particles, prepared by one-pot Pickering emulsion Polymerization in aqueous medium, were used to reinforce silicone rubber. Bearing both Polymer moieties and Si-OH groups on the surface, these raspberry-like particles were better dispersed in the silicone rubber matrix; therefore the mechanical performance of the resultant particle - silicone rubber Composites was significantly enhanced. With 25 phr SiO2@Polymer Composite particles, the tensile strength, elongation at break and hardness were 2.02 MPa, 129% and 38, respectively. Further increasing the filler amount resulted in decrease of the tensile strength and modulus. In the meantime, although there was a large fraction of Polymeric phase in the Composite particles, the thermal stability of the resultant particle - silicone rubber Composites was not significantly reduced, especially for particle loading exceeding 10 phr. These raspberry-like SiO2@Polymer Composite particles are easily produced on a large scale in an environmentally friendly and cost-effective way; thus these are promising novel fillers to reinforce silicone rubber.
