“…Compared with our previous salt spray test results of Cu/OMMT/LLDPE nanocomposite , we find that dickite just like montmorillonite can combine nano‐Cu to produce the synergistic effect on improving the anticorrosion properties of LLDPE matrix. Dickite and montmorillonite are both layered silicate minerals, but they have different layered structure.…”

A novel anticorrosion packaging nanocomposite composed of LLDPE (linear low‐density polyethylene), nano‐sized Cu, and exfoliated dickite was prepared via melt mixing combined with melt extruding process. X‐ray diffraction and transmission electron microscopy (TEM) were employed to characterize the resultant nanocomposite. The results showed that most dickite layers were exfoliated and the nano‐Cu particles were distributed uniformly in the polymer matrix. The characteristic properties of the Cu/dickite/LLDPE nanocomposite were investigated using salt spray test, thermogravimetry analysis, mechanical test, and antibacterial test. The salt spray test results showed that exfoliated dickite and nano‐Cu improved the anticorrosion properties of the Cu/dickite/LLDPE nanocomposite in simulated ocean environment, respectively. Furthermore, the coexistence of exfoliated dickite and nano‐Cu in Cu/dickite/LLDPE nanocomposite produced a synergistic effect on enhancing the anticorrosion properties. Additionally, the co‐incorporation of exfoliated dickite and nano‐Cu in LLDPE matrix also improved the thermal‐oxidative stability and mechanical properties of the polymer matrix. The bactericidal properties evaluation showed that the Cu/dickite/LLDPE nanocomposite had better bactericidal ability because of the presence of nano‐Cu in LLDPE matrix. POLYM.

“…Cu/OMMT/LLDPE nanocomposites were prepared according to this idea. The used clay for preparing the nanocomposites was montmorillonite and the synergistic effect of Cu and montmorillonite in LLDPE matrix was discovered . We notice that another clay dickite and montmorillonite are both layered silicate minerals.…”

“…The main reason to their modification with organic surfactants is to change their hydrophilic nature to hydrophobic for better compatibility with polymer. These clay mineral nanofillers can improve the mechanical and thermal properties [6][7], anticorrosion properties [8], gas permeability resistance [9] and fire retardancy [10] of polymers. Various preparation procedures of the antibacterial CPN were published [8][9][11][12][13].…”

Vermiculite (Ver) enriched with silver and copper was used as nanofiller to the polyethylene (PE) matrix. Specifically, the low density polyethylene (LDPE) was chosen as a matrix. The samples Ver-Ag,Cu were prepared by shaking of Ver with the aqueous solutions of silver and copper nitrate. The mixtures of the Ver nanofillers and PE were homogenized by melt compounding technique and further thin plates were pressed from stiff matter of PE with Ver nanofiller. The exfoliation of the powdery Ver nanofillers in PE matrix was characterized by the X-ray diffraction analysis of thin plates. Distribution of Ver nanofiller in PE matrix was observed by Light microscopy. The reinforcing effect of nanofillers onto PE matrix was studied by creep experiment. Antibacterial activity of powder Ver-Ag,Cu samples and surfaces of PE/Ver-Ag,Cu samples was tested on the Gram-positive bacteria Enterococcus faecalis. All tested PE/Ver-Ag,Cu surfaces showed good antibacterial behaviour after 24 h in comparison to pure PE. The number of colonies decreased from the countless number to several hundred colonies.

“…Additionally, Nguyen et al [9] concluded that some mechanical characteristics of LDPE/modified TiO2 nanocomposites increased compared to the based LDPE/unmodified structures. Xue et al [21] verified that the coexistence of organo-montmorillonite (OMMT) and nano-Cu in Cu/OMMT/LLDPE nanocomposites may improve the anticorrosion properties of samples.…”

In this paper, a 23 factorial design analysis was used to study the parameters affecting the mechanical characteristics of polypropylene/linear low-density polyethylene/nano-titanium dioxide (PP/LLDPE/TiO2) nanocomposites, and to optimize these factors in order to predict the maximum ultimate tensile strength (UTS), elastic modulus (EM), and yield strength (YS) simultaneously. To do this, two levels of nano-titanium dioxide (TiO2), linear low-density polyethylene (LLDPE) and styrene-ethylene-butylene-styrene (SEBS) as the coupling agent were selected and eight experiments were conducted for every response. The most effective factors influencing the UTS, EM, and YS were found, and acceptable prediction regression models were taken. One noted that nanoparticles increased the elastic modulus. The attendance of high levels of LLDPE and SEBS resulted in a decrease in YS and UTS. Moreover, the optimum values of variables were determined by using the contour plot.
