On the other hand, PEEK-WC is widely employed to produce membranes, also after chemical modifications, with different morphologies and different techniques, and for many applications. In this work transparent PEEK-WC membranes were produced, modifying just the preparation conditions. Transparent membranes find a lot of applications, from display protection film, in odontology, as impermeable pellicles, in cultural heritage protection, but also in traditional fields, as gas separation. Not all the membranes are transparent, but it seems clear that the oxygen presence during membrane formation is r...

Abstract This review is devoted to recent progress in the design of anticancer drug delivery systems with participation of unique polysaccharide gellan gum. At first a brief literature survey on conformational and phase behavior of gellan gum as a function of external stimuli, such as temperature, pH, salt addition etc. is presented. Then the immobilization protocol of anticancer drugs and gold nanoparticles within gellan-based hydrogel matrix is discussed. Release of anticancer drugs from gellan gel matrix to outer solution is considered. Cytotoxicity of gellan gum-immobilized gold nanoparticles together with their anticancer activity is summarized.

       JUNIPER PUBLISHERS-   ACADEMIC JOURNAL OF POLYMER SCIENCE Abstract Semi-aromatic copolyamides owing to both possessing the machinability of aliphatic polyamides and the high temperature resistance of aromatic polyamides, were widely used in automotive and electronic fields. To better summarizes the research on the structure-property relationship of semi-aromatic copolyamides, the review was carried out from three aspects: synthesis, structure characterization and structure-property relationship. The study of structure-property relationship can be applied to the modification process of semi-aromatic copolyamides, and it can shed light on the design and actual production process. Keywords:  Copolyamides; Solution Polycondensation; Sequence structure; Structure-Property Relationship Introduction Semi-aromatic copolyamides contain both aliphatic and aromatic segments, therefore possess some unique properties, such as high mechanical strength, high temper...

     JUNIPER PUBLISHERS-   ACADEMIC JOURNAL OF POLYMER SCIENCE Abstract Polymer pollution is a dangerous environmental problem that can lead to the spread of toxic chemicals and microplastics throughout aquatic biomes. Commonly littered plastic from consumer goods and products with a limited or single use can be embedded with photocatalysts to avoid an increase in the amount of plastic present in Earth’s bodies of water. The photocatalyst nanoparticles, less than 100 nm particle size, were integrated into polyethylene terephthalate, high-density polyethylene, low-density polyethylene, and polystyrene and exposed under ultraviolet light over two independent experimental trials examining both the environmental factors impacting decay and the physical parameters required to implement this solution on a large scale. The plastics were chosen due to their prolific use in items such as grocery bags, bottles, and packaging. The first half of the project examined the effects ...
