BOOK-CHAPTER 0 Reads 0 Citations Polymer Nanocomposites Published: 01 January 2018
Handbook of Thermal Analysis and Calorimetry, doi: 10.1016/b978-0-444-64062-8.00003-6
In this chapter, application of different thermal analysis methods, such as differential scanning calorimetry (DSC), differential fast scanning calorimetry (DFSC) and modulated temperature DSC (TMDSC), thermogravimetric analysis (TGA) and TGA hyphenated with FTIR and MS, thermomechanical analysis (TMA), dynamic mechanical analysis (DMA), localized thermal analysis and dielectric thermal analysis (DETA) for studying of polymer nanocomposites has been described. Thermal analysis methods are useful tools that enable better understanding of the “nano-effects” observed in polymeric nanocomposites and are efficiently utilized in the determination of phase transitions and degradation processes of nanostructured polymeric materials. To describe the property changes of polymer matrix it is crucial to recognize macromolecules’ phase behavior and decomposition routes in the presence of nanoparticles of different size and shape, which may considerably change not only thermal, but also mechanical, barrier, and optical properties, as well as flame resistance. Recent developments in the area of new methods, such as DFSC, applied for studying phase transitions under the state far from thermodynamic equilibrium have been reported, too.
Article 0 Reads 0 Citations Physicochemical and antibacterial properties of polyurethane coatings modified by ZnO Published: 27 December 2017
Polymers for Advanced Technologies, doi: 10.1002/pat.4217
The synthesis of polyurethane nanocomposite coatings containing 1% to 5% suitably dispersed ZnO by 1-stage polyaddition process in the bulk using 4,4′-methylenebis(cyclohexyl isocyanate), poly(ε-caprolactone)diol, and 1,4-butanediol was performed. Infrared and nuclear magnetic resonance spectra confirmed the structure of obtained polyurethanes. Scanning electron microscope and energy dispersive X-ray analyzer methods showed randomly distributed ZnO in a polyurethane matrix. The differential scanning calorimetry and wide-angle X-ray diffraction patterns were used for the microstructural assessment of the obtained materials. Antimicrobial properties of ZnO and the effect of this modifier on the hydrophobicity of the coatings were demonstrated. The obtained coatings were characterized in terms of the mechanical properties and changes during incubation in a Baxter saline solution.
Article 0 Reads 2 Citations Mechanical and thermal properties of carbon-nanotube-reinforced self-healing polyurethanes Published: 11 July 2017
Journal of Materials Science, doi: 10.1007/s10853-017-1353-6
The study was conducted to synthesize self-healing polyurethanes (PUs) in the presence of multiwalled carbon nanotubes (CNTs). Measurements of the self-healing ability of PUs synthesized from N3300 isocyanate and polytetrahydrofuran with various contents of CNTs were taken. The mechanical and thermal properties were studied to analyse healing efficiency in experimentally damaged composite samples. The addition of CNTs results in a slight decrease in the self-healing efficiency of nanocomposites as compared to pure PUs. PU samples containing 40% content of soft segments self-healed much better than the samples with 50% content of soft segments. Functionalized carbon nanotubes CNT-OH due to presence of surface functional groups interact with PU chains, which results in an increase in the healing efficiency of mechanical strength and thermal conductivity of nanocomposites.
BOOK-CHAPTER 0 Reads 0 Citations Phase Change Nanomaterials for Thermal Energy Storage Published: 11 February 2017
Nanotechnology for Energy Sustainability, doi: 10.1002/9783527696109.ch20
Phase change materials (PCMs) are currently an important class of modern materials used for storage of thermal energy coming from renewable energy sources such as solar energy or geothermal energy. PCMs are used in modern applications such as smart textiles, biomedical devices, and electronics and automotive industry. These materials accumulate thermal energy in the form of latent heat of phase transition that provides a greater energy storage density with a smaller temperature difference between storing and releasing heat, compared to the sensible heat storage method. Since the 1980s, different groups of materials have been investigated as potential phase change materials, including salts and salt hydrates, paraffins, saturated fatty acids, and polymeric materials, for example, poly(ethylene glycol). Recently, a growing interest in application of nanotechnology and nanomaterials to improve properties, usability, and processability of PCMs has been observed. This chapter reviews the current state of the art in nanotechnology and nanomaterials application for phase change materials to develop composites with improved product performance and safety.
Article 0 Reads 0 Citations Polyurethane cationomers modified by polysiloxane Published: 02 February 2017
Polymers for Advanced Technologies, doi: 10.1002/pat.4013
The synthesis of waterborne polyurethane cationomers was successfully carried out. Different proportions of α,ω-di(hydroxyl)polydimethylsiloxane (PDMS) modifier (0–7.3% by weight) were applied. Analysis of IR spectra confirmed the structure of obtained polyurethane cationomers and the incorporation of a modifier into the polyurethane structure. The differential scanning calorimetry (DSC) method was employed for the microstructural assessment of the obtained materials. A clear decrease of the degradation temperature with increasing amounts of incorporated PDMS indicates immiscibility part of the polysiloxane segments with soft segments derived from polyethylene glycol. Changes were discussed in the free surface energy and its components, as calculated independently according to the method suggested by Owens–Wendt, in relation to chemical and physical structures of cationomers as well as morphology of coating surfaces obtained from those cationomers. Test results of contact angle measurements indicated that with increasing content of the polysiloxane in the analyzed films, the contact angles increase. Copyright © 2017 John Wiley & Sons, Ltd.
