“…39,40 The advantage of treating polymeric materials using plasma modification is that the reactions occur only on the surface and do not change the polymer's bulk properties significantly. 39,40 In this work, we tailored the surface properties of polypropylene by plasma-assisted polydopamine functionalization. Dopamine was chosen because it is prone to oxidative selfpolymerization that results in the formation of thin layers on various types of substrates, thus providing one-step surface functionalization.…”

Polypropylene is one of the most widely used commercial commodity polymers; among many other applications, it is used for electronic and structural applications. Despite its commercial importance, the hydrophobic nature of polypropylene limits its successful application in some fields, in particular for the preparation of polymer nanocomposites. Here, a facile, plasma-assisted, biomimetic, environmentally friendly method was developed to enhance the interfacial interactions in polymer nanocomposites by modifying the surface of polypropylene. Plasma treated polypropylene was surface-modified with polydopamine (PDA) in an aqueous medium without employing other chemicals. The surface modification strategy used here was based on the easy self-polymerization and strong adhesion characteristics of dopamine (DA) under ambient laboratory conditions. The changes in surface characteristics of polypropylene were investigated using FTIR, TGA, and Raman spectroscopy. Subsequently, the surface modified polypropylene was used as the matrix to prepare SiO2-reinforced polymer nanocomposites. These nanocomposites demonstrated superior properties compared to nanocomposites prepared using pristine polypropylene. This simple, environmentally friendly, green method of modifying polypropylene indicated that polydopamine-functionalized polypropylene is a promising material for various high-performance applications.

“…However, it has poor wettability, printability, and adhesion owing to its hydrophobic characteristics [3]. Many techniques such as corona discharges, ultraviolet irradiation, and electron bombardment have been used to overcome these problems by modifying the surface properties [4][5][6][7]. These techniques increase the surface-free energy and wettability of a film surface by incorporating oxygen-containing polar functional groups onto the film surface.…”

“…Ethylene vinyl acetate (EVA) copolymer is a sort of thermoplastic elastomeric plastic. 1,2 EVA (containing 12-30% VA) can be used to produce independent micro porous foam materials. Due to the existence of cells in the matrix, EVA foams exhibit light weight (in the range 150-250 kg/m 3 ), cushioning performance, cost reduction, thermal and acoustic insulation.…”

“…4,5 Meanwhile, in today's highly demanding life, traditional EVA foams can no longer satisfy ever increasing demand for quality life, which calls for reduced density without sacrificing the mechanical properties. 1 College of Resource and Environment, Shaanxi University of Science and Technology, Xi'an, China 2 Key Laboratory of Chemistry and Technology for Light Chemical Industry, Ministry of Education, Xi'an, China 3 Key Laboratory of Ministry of Education on Chemical Science and Technology of Light Chemical Additives, Shaanxi University of Science and Technology, Xi'an, China Nanocomposites, which had been used to improve the mechanical properties of polymers, have been of major interest to many scholars. 6,7 Polymer nanocomposites prepared from montmorillonite (MMT), with a high aspect ratio, may achieve significant improvements in mechanical and thermal properties at low filler content of MMT.…”

Nanocomposite foams, based on ethylene vinyl acetate copolymer, were prepared by melt blending of ethylene vinyl acetate with organically modified montmorillonite and at a high curing pressure of the blends. The organically modified montmorillonites were obtained by the modification of montmorillonite with octadecyl trimethyl ammonium chloride, dimethyl octadecyl hydroxy ethyl ammonium nitrate and dioctadecyl dimethyl ammonium chloride as the intercalating agent. The intercalation effect of montmorillonite layers by the tetraalkylammonium cations was characterized by X-ray diffraction. The state of organically modified montmorillonite in the blends was studied using transmission electron microscopy and the cellular microstructure of the foamed samples was observed by scanning electron microscope. The effects of tetraalkylammonium modification of montmorillonite on the cellular structure and the mechanical properties of the ethylene vinyl acetate-based foams were investigated. It was found that organically modified montmorillonites with different alkyl chains played important role in the formation of the microstructure and the mechanical properties of the ethylene vinyl acetate/organically modified montmorillonite nanocomposite foams. With the alkyl chains, it was possible to obtain ethylene vinyl acetate nanocomposite foams with significantly lowered density and improved mechanical properties.
