     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 Opinion The flexible microwave absorbers are being considered as new generation materials which have wide applications in the local area network, wireless data communication, radar systems, satellite communication, satellite television, electronic devices and the heating systems, etc. A number of dielectric, magnetic, and magneto – dielectric materials are frequently used as microwave absorbers for various applications. The carbonaceous materials like carbon fiber, carbon nanotubes, graphite and graphene and inorganic materials like metals, metal oxides, and conducting alloys are used to develop the dielectric microwave absorber because of their conducting loss property. The magnetic materials like magnetic metals and their compounds are used to produce magnetic microwave absorber due to their hysteresis loss property. The combined features of the dielectric and magnetic materials together assist in the preparat...

   JUNIPER PUBLISHERS-   ACADEMIC JOURNAL OF POLYMER SCIENCE Abstract Oral route is the most convenient and widely used method of drug administration, representing about 90% of all therapies used. It displays great advantages, such as being non-invasive, easy to administer (with the consequent high patient compliance) and cost-effective. However, serious drawbacks to conventional oral dosage forms are imposed by the gastrointestinal tract. Large fluctuations in drug bioavailability are found due to the influence of physiological factors such as variations in pH, high enzymatic activity and gastric emptying. This is the reason why frequent drug administrations are required to maintain the therapeutic plasma level of the drug. Gastroretentive Drug Delivery Systems (GRDDS) have emerged as an ideal approach to overcome these drawbacks. They are designed to prolong the gastric residence time (GRT) of the dosage forms in the stomach so that the time between dose administration ...
