“…Moreover, these CNT/PET films also have superior mechanical performance and similar or even lower electrical resistance values compared to ITO. [ 120 ] Besides, the addition of iron (II,III) oxide (Fe 3 O 4 ) [ 155 ] or manganese zinc ferrite ([Mn,Zn]Fe 2 O 4 ) [ 156 ] can bring magnetic properties to these nanocomposites while retaining an optically transparent appearance.…”

Optical transparency is an important property for a material, especially in certain fields like packaging, glazing, and displays. Existing commercial transparent polymeric materials are mostly amorphous. Semicrystalline polymers have often-superior chemical resistance and mechanical properties particularly at elevated temperatures or after solid-state drawing but they appear opaque or white in most cases. This review describes the present state-of-the-art of methodologies of fabricating optically transparent materials from semicrystalline polymers. A distinction is made between isotropic, biaxially stretched, and uniaxially stretched semicrystalline polymers. Furthermore, some functionalities of transparent nanocomposites based on semicrystalline polymers are also discussed. This review aims to provide guidelines regarding the principles of manufacturing transparent high-performance semicrystalline polymers and their nanocomposites for potential applications in fields like packaging, building, and construction, aerospace, automotive, and opto-electronics.

The new magnetic and heat-resistant polyamide ether (PAE)/graphene oxide (GO) nanocomposites were prepared by blending PAE with modified GO. Furthermore, a novel PAE containing flexible ether, methyl, and triphenylmethane moiety in the main chain of PAE was prepared by direct polycondensation reaction of a diamine and 4,4′-(butane-1,4-diylbis(oxy))dibenzoic acid (9). The prepared PAE was characterized using various techniques. The obtained PAEs were readily soluble in various aprotic polar solvents at room temperature. The incorporation of bulky aryl pendant groups and flexible ether linkage into the backbones of polyamide may provide beneficial effects for solubility, as this approach produces a separate chain of the polymer, which makes weaker of hydrogen bonds. GO, which synthesized by the Hummer method, was modified with tetraethylenepentamine (GO-TEPA) and sequentially magnetized with Fe3O4 nanoparticles via chemical coprecipitation (GO-TEPA@Fe3O4). The PAE/GO/TEPA@Fe3O4 nanocomposite films, PAE/GO-TEPA@Fe3O4, were also synthesized as a heat-resistant and superparamagnetic nanocomposites, which were characterized using different analyses, such as field emission scanning electron microscopy, X-ray diffraction, energy-dispersive X-ray, thermogravimetric analysis (TGA), vibrating sample magnetometer (VSM), and Fourier transform infrared techniques. TGA of nanocomposites exhibit higher degradation temperature than that of neat PAE, which is an indication of high levels of interfacial interaction and dispersion.

A new phosphorus-based organic additive (PDA) was designed and successfully synthesized using a three-component reaction for improvement of the thermal and combustion resistance of polylactic acid (PLA). For compensate for mechanical properties of PLA, hydroxyapatite nanoparticles was modified via in situ surface modification with PDA and was used for preparation of PLA nanocomposites. The structure and morphology as well as thermal, combustion, and mechanical properties of the all PLA systems were investigated. The X-ray diffraction (XRD) and field-emission scanning electron microscopy (FE-SEM) results indicated that the presence of PDA as surface modifier has been necessary for a desirable dispersion of hydroxyapatite (HA) nanoparticles in the PLA matrix. The thermal, combustion, and mechanical properties of the PLA system films were investigated using thermogravimetric analysis (TGA), microscale combustion calorimeter (MCC), and tensile test, respectively. The initial decomposition temperature and char residue of PLA containing 6 mass% of PDA along with 2 mass% HA nanoparticles were increased 20°C and 12% respectively, compared with that of the neat PLA. The peak of heat release rate was decreased from 566 W/g for the neat PLA to 412 W/g for PLA containing 2 mass% of PDA along with 6 mass% HA nanoparticles. By incorporation of only 2 mass% HA nanoparticles and 6 mass% of PDA, the tensile strength was obtained 51 MPa higher than that of the neat PLA.
