                                 JUNIPER PUBLISHERS-   ACADEMIC JOURNAL OF POLYMER SCIENCE Introduction Polyetheretherketone (PEEK) is a promising implant material because of its excellent mechanical characteristics. Although this polymer is a standard material in spinal applications, PEEK has the disadvantage by its relative bio-inertness [1]. This is the reason why coating technologies have built an impressive catalogue of success in many different applications: With a growing need for coating technologies to functionalize the surface of polymeric medical devices, the medical industry saw enormous growth in coating application onto medical devices. Various types of coatings technologies, coating materials and substances are available to date: Spanning from plasma spray coating technologies to dip coating techniques, from titanium or hydroxyapatite, all which enhance cell attachment onto orthopedic implants. But there are also various risks associated with the materials and methods me

     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 of water and light

   JUNIPER PUBLISHERS-   ACADEMIC JOURNAL OF POLYMER SCIENCE Abstract This study aims to design some medicinally important biopolymer based Nano carriers. The study undertakes synthesis, characterization of Chitosan-co-lactic acid nanoparticles and optimization of swelling ratio. The Chitosan-co-lactic acid nanoparticles were prepared by the shaking of lactic acid emulsion in Chitosan solution by emulsion crosslinking method and characterised by transmission electron microscope (TEM) analysis (size), and Fourier transform infrared spectra (FTIR) (structural) and SEM (morphology). The particles were dispersed in a phosphate buffer saline (PBS) and the swelling response of these nanoparticles was studied as a function of chemical composition, pH and temperature of swelling medium. To determine the encapsulation efficiency, a centrifugation method was applied. Also, the assessment of biocompatibility has been made on the basis of two in-vitro test which are BSA adsorption test and haemoly
