“…They are characterized by high mechanical strength and modulus, and due to their hollow nanostructure they are widely used for loading and controlled release of functional compounds (Makaremi et al, 2017;Yang et al, 2016;Huang et al, 2016;Saif and Asif, 2015;Lvov et al, 2016a). HNTs are used in, e.g., self-healing anticorrosive coatings (Wei et al, 2015), hydrogen production and storage (Sahiner and Sengel, 2017;Jin et al, 2017), pharmaceutical excipients (Hanif et al, 2016;Lvov et al, 2016b;Yendluri et al, 2017), biomedical applications Bonifacio et al, 2017), cosmetics (Saif and Asif, 2015), active food packaging materials (Shemesh et al, 2016;Tas et al, 2017;Krepker et al, 2017), water treatment (Yu et al, 2016), and for improvement the mechanical properties and thermal stability of polymer composites (Liu et al, 2014). Globally, HNTs annual production is over 50,000 metric tonnes (Lvov et al, 2008), which is similar to that of carbon fibers (40,000 t/y; Gutiérrez and Bono, 2013), and approximately 10 times higher than the production of carbon nanotubes which is only ca.…”

“…The product is used for example in active food packaging materials, which have been reported to reduce bacterial growth by up to seven orders of magnitude, thereby increasing the shelf life of perishable foods (Shemesh et al, 2016;Tas et al, 2017;Krepker et al, 2017). Here we assessed workers inhalation exposure by measuring air concentrations using diffusion chargers and by sampling airborne particles for gravimetric and electron microscopy analysis.…”

A B S T R A C THalloysite nanotubes (HNTs) are abundant naturally-occurring hollow aluminosilicate clay mineral fibers with a typical diameter < 100 nm and an aspect ratio of up to 200. Here we assessed the potential inhalation exposure to HNTs in an industrial research laboratory. Inside a fume hood, ten times 100 g of HNTs were poured at rate of 0.5 kg min . Inside the fume hood, the respirable mass concentration was 143 μg m −3 including background particles.Outside the fume hood we did not measure elevated concentrations. We classified 1895 particles according to their length and aspect ratio. Five particles were in aspect ratio > 3 and in length > 2 μm. These particles were agglomerated and/or aggregated particles where the longest individual fiber was 2 μm in length. The occupational exposure limits for refractory mineral fibers vary from 0.1 to 2 fibers cm −3. Following standard protocols for fiber analysis, detection of 0.1 fibers cm −3 would require analysis on 4 × 10 4 images when the filter loading is good. Thus, the fiber sampling and quantification procedures needs to be improved significantly if nanofibers < 100 nm in diameter are included in regulatory exposure assessment. Due to very limited toxicological information of HNTs we recommend avoiding inhalation exposure.

“…o improve the storage functionality of polyethylene film as a packaging material, efforts have been made to develop various packaging technologies, including modified atmosphere packaging (MAP), and controlled atmosphere packaging (CAP). [1][2][3] The packaging of fruit and vegetables in particular is problematic. Over time after packaging, it can lead to the generation of off-flavors, and the emitting of ethylene gas resulting from respiration.…”

This work reports the preparation of ceramic hybrid films with illite-polyethylene composites analyzed as a function of concentration of added illite in polyethylene. The enhancement of oxygen and water-vapor transmission rate of illite-polyethylene film was evaluated to determine its influence on the freshness in fruit packaging. Particle size of illite materials was controlled in the range of 1~10 µm and then mixed with LDPE to form the masterbatch. Ceramic hybrid films were prepared through a blown film making process. To determine the dispersity and abundancy of illite materials in the polyethylene matrix, various characterizations of illite-PE hybrid masterbatch and films were performed using SEM, TGA, and FT-IR. The oxygen and water-vapor transmission rate of illite-polyethylene film was found to be two times higher than that of LDPE film.

“…Among the polyolefin‐based thermoplastics, low‐density polyethylene (LDPE) has recently been in the limelight due to its unique properties such as low weight, chemical inertness, easy processability and low cost . LDPE has been widely applied as a highly rated material for packaging in a wide variety of industries including food, furniture, electronics and electrical industries . However, the enhancement of optical, thermal and mechanical properties of LDPE to meet these various demands is still a challenge.…”

The variation in physicochemical properties on incorporation of unmodified reduced graphite oxide (rGO) into a low‐density polyethylene (LDPE) matrix has received much attention. Herein, a simple method is developed for the fabrication of LDPE/rGO nanocomposites using a solvent casting method. The UV‐visible spectra showed that addition of rGO can effectively cut off the short‐wavelength UV‐B light, which resists the occurrence of photoreaction. The stiffness of the LDPE/rGO nanocomposites was improved by 45% with an increase of modulus of elasticity as the rGO content increases. This is slightly opposite to the small decrease of the nanocomposite tensile strength. The addition of rGO to LDPE improved the thermal stability and degree of crystallization of LDPE/rGO nanocomposites when the rGO content increases from 0.025 to 1 wt%. The gas barrier property was also improved by 26% with 0.3 wt% of rGO. The dielectric property of the LDPE/rGO nanocomposites was also evaluated for industrial electronics application and the dielectric constant increases 50% compared with the neat LDPE when 0.1–1 wt% rGO was added. Results obtained clearly indicate the feasibility of using unmodified rGO to improve the properties of LDPE matrix for meeting the performance requirements for intended use in packaging industries. © 2018 Society of Chemical Industry
