                                             JUNIPER PUBLISHERS-   ACADEMIC JOURNAL OF POLYMER SCIENCE Abstract The mini-review is devoted to the recent investigation the role of cage effect during photopolymerization. Benzophenone was selected as a photoinitiator of polymerization. Introduction Free-radical photopolymerization (UV-cure) of organic coatings is a very important process that has been used for more than half a century. Academic and industrial researchers study the basics of this complex process [1-4] In this mini review we will briefly consider the important role of low MW free radicals of photoinitiators (PIs) and the excited triplet states of PIs in photopolymerization. On the contrary, residual PIs in the cured coatings and other low MW photoreactive species in the cured coatings/polymers lead to a negative effect: photodecomposition of polymers outdoo...

   JUNIPER PUBLISHERS-   ACADEMIC JOURNAL OF POLYMER SCIENCE Abstract Some extraordinary determinations have been made to investigate the epoxy-based nano-composite properties and the viscoelastic curing kinetics for several different industrial applications, such as aircraft, wind energy, defense, and automotive applications. In this research work, the rheological properties of epoxy-based nano-composites containing altered percentages (0%, 1%, 2%, 4%) of nanoparticles (such as carbon [C] and zeolite) were investigated by utilizing a dynamic shear rheological analyzer. Here, the curing kinetics of commercially available thermosetting epoxy resin (Loctite EA 9394 Aero) was studied in detail. It was found that the addition of nanoparticles, such as CB and zeolite in varying proportions (0%, 1%, 2%, and 4%) significantly improved the viscoelastic properties and the curing kinetics (storage modulus, loss modulus, and tan δ) of the nano-composites, which may be helpful in bet...

     JUNIPER PUBLISHERS-   ACADEMIC JOURNAL OF POLYMER SCIENCE Abstract This review presents poly(dimethylphosphazene) (PDMP), as the simplest representative of poly[(organo)phosphazenes], which was used as the additive into commercial polymer mixtures. This mixture was electrostatically spun. The formation and behaviours, such as wettability, of PDMP modified layers, were investigated. Phosphazene; Poly(dimethylphosphazene); Electrospinning; Nanofibers Introduction and Theory The effort to make new materials from already well-known compounds is the goal of many current scientists. The synthetic possibilities in polyphosphazenes chemistry has enabled the development of a wide range of matrixes with a variety of physical, chemical, and biological properties. Poly[(organo)phosphazenes] introduce a unique class of extremely versatile compounds with huge potential for various applications. Due to their high ability to be functionalized by a wide range of side groups, [1]...

       JUNIPER PUBLISHERS-   ACADEMIC JOURNAL OF POLYMER SCIENCE Abstract A call for novel material, new ideas, applications, and techniques are still and will be challenging all the time. The increased development of science and modern technology allows one to use a high-throughput search for novel materials that could give positive feedback in different areas of life. With increasing demand for high performance materials, the focus of recent researches has been to produce products with enhanced properties at minimal changes in the equipment, process and cost of inputs. The addition of clay minerals or nano-metal oxides to the polymers is to improve the polymer properties, their wide and demand characteristics or desired potential applications by producing the polymer nanocomposites. Scanning and transmission electron microscopy have led to a deeper understanding of polymer nanocomposites, a better account surface topology, structure and morphology. Keywords:...
