Overview on the Synthesis and Characteristics of Polystyrene
Abstract: Polystyrene, a synthetic aromatic polymer, is one of the most wide spread polymers in the world. The monomer is styrene (vinylbenzene)- a petroleum based liquid hydrocarbon. Polystyrene can be solid or foamed. It was first discovered by a German apothecary Edmon Simon as far back as in 1839 from the resin of Turkish sweet gum trees. Polystyrene is formed by a polymerization method known as chain growth. Physically, it is …

Stability Analysis of Mahua Seed and Waste Polystyrene Co-pyrolytic Oil
Abstract: Biomass pyrolytic oil is a complex mixture of organic compounds and obtained in a non-equilibrium state. Hence, the physical properties of bio-oil such as calorific value, viscosity, pH, density, flow ability and chemical compositions vary during storage. In this study, co-pyrolysis of Mahua seed was performed with waste polystyrene and studied the fuel properties and composition. The co-pyrolytic oil was produced at 2:1 ratio of seed to waste polystyrene using …

Effect of Polystyrene Nanoparticles from Recycled Waste Material on the Properties of Asphalt
Abstract: There is growing concern in many parts of the world over the increasing stress placed on the asphaltic material used to pave streets, highways, and runways due to higher traffic volumes and climatic and other environmental factors (e.g., heat, storms, ultraviolet radiation). Adding asphalt modifiers (e.g., polymers) on both the micro and macro scales has improved this material’s physical and rheological properties, but recent research, especially in the field of …

MISCIBILITY EVALUATION OF POLYSTYRENE AND POLY(METHYL METHACRYLATE) BLENDS: ANALYSIS OF MECHANICAL, THERMAL, MORPHOLOGY, AND VISCOELASTIC PROPERTIES
Abstract: Partially miscible blend of polystyrene (PS) and poly(methyl methacrylate) (PMMA) was successfully prepared employing melt blending technique. In order to impart miscibility, the processing was carried out at temperature above upper critical solution temperature (UCST) as studied from cloud point measurements. The complex modulii and viscosity derived from melt rheology analysis as a function of angular frequency were also used to study the effect of PMMA loading on the miscibility …

A Brief Discussion on Plastic Wastes Sortation Procedures
Abstract: Recycling plastic is the procedure of retrieving waste plastic products and reprocessing the material into similar or sometimes completely different form of products. As an example, melting down soft drink bottles, boxes and then casting them as plastic chairs and tables. According to the ImpEE project of University of Cambridge, 3 million tonnes of waste plastic were produced a year (2005) in UK and among those 21.3% are produced from …

Case Studies On Synthesis Of PLLA Bioplastic Starting From Food And Agricultural Wastes
Abstract: Polylaevo Lactic Acid (PLLA) is an excellent biopolymer that is biodegradable and has characteristics exactly similar to polystyrene. However, at present, the market price of this biopolymer is significantly higher than polystyrene and other synthetic plastics. The major hindrances to the large scale manufacture of this polymer are the lack of availability of a cheap raw material and the overall economy of synthesis of lactic acid from the same. In …

Removal of Methyl Orange from Wastewater Using Composite Material
Abstract: The textile industry is one of the pollute activities that most consume water. Industrial dyes are dangerous pollutants, resulting from the textile industry. The textile dyes significantly increase inhibit plant growth, enter the food chain, promote toxicity, and carcinogenicity. The removal of textiles dyes is usually proposed via adsorption represents a sustainable solution. A composite material was prepared by polystyrene in combination with commercial activated carbon. A series of experiments …

Using Leather as a Substrate in Rectenna for Devices Consuming Minimal Power
Abstract: This study examines a lightweight, modular receiving wire for power-efficient devices. Despite being compact in size, the suggested receiving wire possesses a high level of directivity and a high transfer rate. Because it is flexible, wearable, tiny, takes little thought, and has amazing characteristics like low dielectric consistency, low misfortune digression, and increased proficiency, polystyrene froth is employed as a substrate. The receiving wire's boundaries, such as return unfortune, gain, …

Synthesis, Structural and Thermal Properties of Nanoporous Silica Aerogels
Abstract: Aerogel is a pellucid that has varieties of permeable and fabricated solid materials with remarkably low density. It has an exceptional thermal insulation and its structure varies from analogous to foamed polystyrene during solid state. Aerogels are considerably the lightest when solid due to presence of air by volume, which is around 99.8%. For extracting aerogels, air or other specific types of gas are used; heat therapy is also used …
