“…[21] In polymer nanocomposites, the polymer and nanomaterial components usually act as a matrix (substrate) and nanofiller, respectively. [22] As an example, nanocomposite films can be produced by mixing 3 wt.% of the specific jute nanofibrils. [22][23][24] The word fillers in nanocomposites are usually reminiscent of the nanoparticles, but it can also be applied to nanofibrils (nanofibers).…”

Separating valuable materials such as dyes from wastewater using membranes and returning them to the production line is a desirable environmental and economical procedure. However, sometimes, besides filtration, adsorption, and separation processes, pollutant destruction also can be suitable using photocatalytic membranes. The art of producing nanohybrid materials in contrast with nanocomposites encompasses nanomaterial synthesis as a new product with different properties from raw materials for nanohybrids versus the composition of nanomaterials for nanocomposites. According to the findings of this research, confirming proper synthesis of nanohybrid is one challenge that can be overcome by different analyses, other researchers' reports, and the theoretical assessment of physical or chemical reactions. The application of organic‐inorganic nanomaterials and frameworks is another challenge that is discussed in the present work. According to the findings, Nanohybrid Membranes (NHMs) can achieve 100% decolorization, but cannot eliminate salts and dyes, although the removal efficiency is notable for some salts, especially divalent salts. Hydrophilicity, antifouling properties, flux, pressure, costs, usage frequency, and mechanical, chemical, and thermal stabilities of NHMs should be considered.

“…Researchers have reported that nanofillers (e.g., carbon nanotubes or nano-semiconductors) can improve some features of polymers, such as their electrical conductivity and mechanical behavior [ 2 , 3 , 4 , 5 , 6 ]. Accordingly, polymer nanocomposites (PNCs) are interesting for the industry due to their enhanced properties, and have been receiving applications in fields such as environmental remediation, energy storage, and biomedicine [ 7 ]. PNCs have also been used successfully in solar cells and light-emitting diodes because of their enhanced thermal conductivity properties [ 8 ].…”

Preparation of Polycarbonate-ZnO Nanocomposite Films: Surface Investigation after UV Irradiation

et al. 2022

View full text Add to dashboard Cite

Polycarbonate (PC)-ZnO films with different percentages of ZnO were prepared by a solution stirring technique and subjected to ultraviolet (UV; λ = 254 nm) irradiation. Structural parameters of the samples and the effects of UV irradiation on the surface properties of the PC and PC-ZnO nanocomposites were evaluated by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), atomic force microscopy (AFM), water contact angle (WCA) measurements, and a Vickers microhardness (HV) tester. The XRD patterns of the nanocomposite films were found to show an increase in crystallinity with the increasing ZnO nanoparticles percentage. The WCA was found to be reduced from 90° to 17° after 15 h of UV irradiation, which could be ascribed to the oxidation of the surface of the samples during the irradiation and exposure of the ZnO nanoparticles, a result that is also supported by the obtained XPS data. The microhardness value of the PC-ZnO films including 30 wt.% ZnO enhanced considerably after UV radiation, which can also be attributed to the exposition of the ZnO nanoparticles after photodegradation of the PC superficial layer of the nanocomposite films.
