Inertness and the indiscriminate use of synthetic polymers leading to increased land and water pollution are of great concern. Plastic is the most useful synthetic polymer, employed in wide range of applications viz. the packaging industries, agriculture, household practices, etc. Unpredicted use of synthetic polymers is leading towards the accumulation of increased solid waste in the natural environment. This affects the natural system and creates various environmental hazards. Plastics are seen as an environmental threat because they are difficult to degrade. This review describes the occurrence and distribution of microbes that are involved in the degradation of both natural and synthetic polymers. Much interest is generated by the degradation of existing plastics using microorganisms. It seems that biological agents and their metabolic enzymes can be exploited as a potent tool for polymer degradation. Bacterial and fungal species are the most abundant biological agents found in nature and have distinct degradation abilities for natural and synthetic polymers.

“…1720, 1630, 3400, and 1220 cm −1 attributed to C=O, C=C, O-H, and C-O (epoxy), respectively [33]. In pristine PC, the strong absorption bands due to the C=O stretching vibration of the carbonate group were observed at 1,780 cm −1 for diphenyl dicarbonates [34]. The absorption bands of the C-O-C stretching vibrations were also identified at the range 1150-1270 cm −1 .…”

The incorporation of carbonaceous nanofillers into polymers can result in significant materials with improved physicochemical properties and novel composite functionalities. In this study, we have fabricated antibacterial, lightweight, transparent, and flexible graphene oxide (GO) reinforced polycarbonate thin films by a facile and low-cost methodology. Solution blending is employed to get a homogeneous mixture of PC-GO composites at various loading of GO, and the thin films are prepared by dry-wet phase inversion technique. Thermal studies and micrographs of the films revealed the incorporation of GO in PC matrix. Microstructure of the thin films showed the homogeneous dispersion of GO at micro-and nanoscales; however, at higher loading of GO (0.7%), significant agglomeration is observed. More importantly, PC-GO composite films exhibited excellent antibacterial activities against E. coli and S. aureus, owing to the antibacterial nature of GO nanoparticles.

This paper focuses on development and characterization of new impact and flame resistant advanced materials based on polyamide / compatibilizer / polycarbonate / glass fibers (GF) functionalized with organo silane. Polyamides (PA) are highly crystalline hard materials, that have high impact resistance, burn slowly or are self-extinguishing. Polycarbonates (PC) are thermoplastic polymers intended for oil and high temperatures resistant materials. To increase impact resistance, polymeric compounds were reinforced with short functionalized glass fibers. The thermoplastic polymeric materials are visionary and materials for the future, with special properties, depending on the type of elastomers, the type of reinforcement material, the ratio of reinforcement, the functionalization of the reinforcing material, the type of functionalization agent, the ratio of elastomer-compatibilizing agent-reinforcing agent, etc. Thus by determining the optimum types and ratios of polycarbonate, polyamide, compatibilizer, functionalized glass fibers and optimal processing conditions and parameters, special properties can be achieved: flame retardant and especially self-extinguishing properties, physical-mechanical, chemical and technological properties, superior to the current standards in the field. Due to their characteristics the new materials can be employed in development of finished goods for the automotive and electrical insulation industry, which must meet European legislation (directives) into force.
