“…Numerous studies have shown that γ-rays penetrate deeper and produce radicals that trigger cross-linked processes. Compared with E-Beam radiation, γ-ray has higher penetration power [22][23][24][25] . The negative charge particles of E-Beam radiation limit its penetration power [26][27][28][29][30] .…”

In some cases, blends containing PVC and LLDPE show low compatibility. Adding styrene-butadiene rubber to the PVC/LLDPE mixtures leads to a noticeable increase in tensile strength and compatibility of the blends. Also, an improvement in tensile strength is observed after incorporating SBR compatibilizer resulting in entirely different gamma irradiation doses. Without a compatibilizer, the mixture exhibits a distributed PVC and LLDPE phase with variable sizes and shapes; even a sizable portion of the domains resemble droplets. Styrene butadiene rubber (SBR) and gamma radiation make mixtures of (PVC/LLDPE) more compatible. The SEM study of the blends demonstrated that adding the compatibilizer resulted in finer blend morphologies with less roughness. At the same time, gamma irradiation reduced this droplet and gave a more smooth surface. Poly(vinyl chloride) (PVC) was chemically modified with four different amino compounds, including ethylene diamine (EDA), aniline (An), p-anisidine (pA) and dimethyl aniline (DMA) for improving the electric conductivity and oil removal capability of the blend polymer. All ionomers were prepared by nucleophilic substitution in a solvent/non-solvent system under mild conditions. This work novelty shows a sustainable route for producing oil adsorption materials by recycling plastic waste. After the amination process of poly(vinyl chloride) the oil adsorption was significantly enhanced.

“…Unfortunately, reports of using other polymerization methods for INCP (other than ROMP, CP, and CTP) are rare. Two recent examples describe the polymerization of acetylene-based monomers, specifically phenyl acetylenes (PA1 and PA2) 71 and propargyl alcohol (PGA), 72 to give substituted-PA backbones (Fig. 9A).…”

“…In the other example, PPGA homopolymers were shown to generate various solventdependent nano-object morphologies. 72 Specifically, polymerizations in chloroform, dimethylformamide (DMF), or water led to the formation of micellular nanospheres, nanostars, or nanonetwork structures, respectively (Fig. 9D).…”

“…Initially, PA was polymerized by using Ziegler–Natta catalysts [ 93 , 94 , 95 ] in which acetylene gas was used. Lately, PA has been produced by using radiation polymerization via ultraviolet [ 96 ], gamma [ 33 ], or glow-discharge [ 97 ] radiations. Recently, PA has been synthesized via ring-opening metathesis polymerization using a cyclooctatetraene (COT), which is much easier to handle than acetylene gas [ 73 ].…”

“…With the tremendous technological development in semi/superconductors that relies on electrically conductive mediums such as conductive polymers [ 30 , 31 , 32 , 33 ], carbon-based fillers [ 34 , 35 ], or metallic particles [ 36 , 37 ], the need for imparting self-healing properties into the conductive substrates has become a necessity. In self-healing and electrically conductive hydrogels, self-repairing behavior is not limited to restoring the mechanical property but also to restoring the electrical conductivity.…”

Electrically conductive materials that are fabricated based on natural polymers have seen significant interest in numerous applications, especially when advanced properties such as self-healing are introduced. In this article review, the hydrogels that are based on natural polymers containing electrically conductive medium were covered, while both irreversible and reversible cross-links are presented. Among the conductive media, a special focus was put on conductive polymers, such as polyaniline, polypyrrole, polyacetylene, and polythiophenes, which can be potentially synthesized from renewable resources. Preparation methods of the conductive irreversible hydrogels that are based on these conductive polymers were reported observing their electrical conductivity values by Siemens per centimeter (S/cm). Additionally, the self-healing systems that were already applied or applicable in electrically conductive hydrogels that are based on natural polymers were presented and classified based on non-covalent or covalent cross-links. The real-time healing, mechanical stability, and electrically conductive values were highlighted.
