“…exploited the CY as a standard method for evaluating LOI of PVC sample containing ZnO nanoparticles in accordance with Van Krevelen and Hoftyzer equation: LOI = 17.5 + 0.4Yc, where Yc is char yield. [ 31 ] Scanning optical microscope images of PVC films were shown in Figure 3. LOI for the PVC nanocomposite films containing 5 wt% and 20 wt% zinc oxide increased from 20.8% for pure PVC film to 27.9% and 28.7%, respectively.…”

As a versatile star product, poly(vinyl chloride) (PVC) has kept active in our daily life all through since it was invented. However, the severe fire hazard and heavy smoke produced during combustion, particularly the extensively used flexible PVC products, have been puzzling manufacturers and researchers for ages. Over the last decade, multifarious flame retardants and smoke suppressants were developed for PVC materials. In this review, combined literature with the results based on the research from our group, recent emerged flame retardants and smoke suppressants for PVC are introduced. Meanwhile, the flame retardant mechanisms and experimental analysis results are described to understand the relationship between characters of flame retardants (including chemical compositions, structures or morphologies) and fire performance of the composites. The potential substitutes for traditional harmful flame retardant antimony trioxide are discussed aiming to the emphasis on increasing prominent environmental concerns. In particular, one section is dedicated to new approaches for the preparation of novel environmentally friendly and high-efficiency flame retardants. It is hoped that this review will not only summarize the new emerged flame retardants and smoke suppressants for PVC, but also provide the new trend to prompt sequent exploration in both academic research and industrial application.

“…Solution methods relatively easily achieve an even dispersion of NPs in polymers, especially those without a melting temperature or with a high molten viscosity as reported by Zarrinkhameh et al [27]. In recent decades, various approaches have been attempted for the dispersion of NPs in polymers, including solution dispersion, mechanical blending, and in situ polymerization with NPs reported by Guo et al [28], each method has its own advantages and disadvantages reported by Ray et al [29].…”

This work proposes an approach to fabricate flexible transparent ultraviolet (UV)-shielding membrane by casting method, which uniformly disperses pristine zinc oxide nanoparticles (NPs) in low-density polyethylene (LDPE). The critical conditions for film fabrication, such as casting temperature, LDPE concentration in the solution, dissolution time, NP concentration, and post hot press cooling processes, are systematically studied. It is found that the casting temperature needs to be close to the melting temperature of LDPE, namely, 115°C, so that transparent film formation without cracks can be guaranteed. NP agglomerates are suppressed if the polymer concentration is controlled below 6%. For good dispersion of NPs, LDPE has to be swelled or unentangled enough in the solution (close to 200 h dissolution time), and then the NP agglomerates can be diminished due to the diffusion of the NPs into the polymer gel (322 h dissolution time). When the NPs are well-dispersed in the LDPE film, the film can completely shield UV light while allowing high transmissivity for the visible light. As the concentration of NPs in the film increases from 4 to 6%, the transmissivity of the film decreases, the tensile strength increases, and the tensile failure strain decreases.

“…Silver thin films can be produced by different methods such as chemical vapor deposition (CVD), sol-gel, physical vapor deposition (PVD), thermal and electron gun beam evaporation, laser deposition, RF, DC sputtering, etc. [7][8][9][10]. In this experimental work magnetron sputtering was employed, since it has many advantages such as low temperature (no agglomeration), high purity, suitable and controllable coating rate.…”

In this work to investigate the effects of using different gases in cold atmospheric plasma (CAP) on surface treatment of silver thin films (100, 120 nm film thickness) He and Ar were employed. Ag was sputtered on glass substrate and X-ray diffraction (XRD) as well as atomic force microscopy (AFM) for structural and morphological studies before and after plasma radiation was carried out. Surface treatment of Ag thin films by CAP increased surface roughness especially with Ar plasma, this rise of surface roughness of Ag thin film leads to make their surface hydrophilic which can be very important for antibacterial activity of Ag films in removal of Escherichia coli (E. coli) which was used as target bacterium. Argon plasma radiation was more effective than helium on both surface morphology and anti-bacterial property. XRD results showed that crystalline orientation of [111] peak of silver remains as preferred orientation, but the grain size did not change that much after plasma treatment. The crystalline size was calculated by Debye-Scherrer formula using peak [111] of Ag samples (as the most intense peak of silver).
