“…Increasing storage modulus by increasing CNC content was also reported by Lu, Wang, and Drzal . Above the glass transition temperature, the dynamic storage modulus is a function of the hydrodynamic effect, well‐known to be dependent on the shape of the filler particles or agglomerates, on the concentration of the filler, and on the fillers interactions with polymer …”

Chickpea flour–crystalline nano‐cellulose (CNC) composite films were prepared using chickpea flour as the film forming material, glycerol as the plasticizer and 2.5 to 10% CNC as reinforcement supplement. Mechanical properties of the composite films increased with an increase in the CNC content up to 5%. By inclusion of CNC up to 10%, the storage modulus of chickpea flour matrix increased by an order of magnitude from 7.3 to 86.4 MPa. The storage modulus of all samples, on the other hand, decreased as temperature increased. The Tg values measured by dynamic mechanical analysis (DMA) and differential scanning calorimetry (DSC) were shifted toward higher temperatures by the addition of CNC. The creep resistance of chickpea flour films increased again up to 5% added CNC, and strain sweep tests confirmed the extension of linear viscoelastic region. X‐ ray diffraction (XRD) confirmed a positive correlation between the degree of crystallinity of chickpea flour composties and CNC content. FTIR spectroscopy confirmed the molecular interaction between chickpea flour, glycerol and CNC. SEM results revealed agglomeration in the structure of the film with the addition of CNC beyond 5% and diminishing of surface homogeneity, while decreasing the pore size of chickpea flour matrix. © 2019 Wiley Periodicals, Inc.

“…Magnetic composites made from thermoplastic polymers can also be fabricated using various processing methods, such as compression molding [171], melt compounding [172], solution casting[173], and melt extrusion [174]. In the fabrication of magnetic thermoplastics, particle agglomeration has been a consistent challenge and alternative approaches have been introduced by using core-shell magnetic polymer nanoparticles with increased stability to prevent aggregation [173].…”

We present an interdisciplinary overview of material engineering and emerging applications of iron oxide nanoparticles. We discuss material engineering of nanoparticles in the broadest sense, emphasizing size and shape control, large-area self-assembly, composite/hybrid structures, and surface engineering. This is followed by a discussion of several non-traditional, emerging applications of iron oxide nanoparticles, including nanoparticle lithography, magnetic particle imaging, magnetic guided drug delivery, and positive contrast agents for magnetic resonance imaging. We conclude with a succinct discussion of the pharmacokinetics pathways of iron oxide nanoparticles in the human body –– an important and required practical consideration for any in vivo biomedical application, followed by a brief outlook of the field.

“…[1][2][3][4][5][6][7] Obtaining metal-filled polymer composites with a wide range of technological and operational properties, their combination and predictable regulation become possible due to a number of factors. First of all, it is the presence of polymer matrices different in nature and, accordingly, in their characteristics (thermosets, 8,9 thermoplastics, 3,10 elastomers, 11,12 hydrogels 13,14 ) and metal fillers (metals, 8,15 noble metals, 16,17 ferromagnets, 18,19 metal alloys, 20,21 bimetals, 22 and hybrids 23 ). The properties of the composite are significantly influenced by the choice of the modification method of the polymer matrix, which is determined by the method of obtaining metal-filler particles (chemical, physical, electrochemical) [24][25][26][27] and the method of introducing the filler into the polymer matrix (synthesis of metal-filler particles in the polymer network, 28 synthesis of metal-filler particles during the formation of the polymer matrix, 29 mixing in the melt 18,30 and solution, 11 polymerization of the monomer in the presence of the metal particles 8,14 ).…”

The effect of the presence of finely dispersed metal fillers of various natures (Zn, Co, Ni) on the thermophysical characteristics (Vick heat resistance, glass transition temperature) of polyvinylpyrrolidone block copolymers with 2-hydroxyethylmethacrylate was studied. It was found that the heat resistance of the obtained composites significantly exceeds the heat resistance of unfilled copolymers and is in the range of 360-395K, depending on the nature and content of the metal filler. The change in heat resistance correlates with the change in glass transition temperature, which was evaluated according to the results of thermomechanical and dynamic mechanical thermal analyses. The results of this work are an additional source to characterize the structure of metal-filled copolymers: they confirm the participation of metal filler particles in the formation of the nodes of the copolymer spatial network, and also prove the formation of a different polymer network structure in the interfacial layer on the surface of the metal particle and in the polymer volume.
