1. Synthetic polymers Synthetic polymers are defined as polymers that are artificially produced in laboratories . These are also known as man-made polymers . Synthetic polymers are derived from petroleum oil, and made by scientists and engineers . Examples of synthetic polymers include nylon, polyethylene, polyester, Teflon, and epoxy. Natural polymers occur in nature and can be extracted. They are often water-based.
2. Significance of Synthetic polymers: Versatility: Synthetic polymers can be engineered to have a wide range of properties, making them suitable for various applications, from packaging materials to automotive parts. Durability: They are often more resistant to wear, chemicals, and environmental factors compared to natural materials, enhancing product longevity . Cost- Effectiveness: The mass production of synthetic polymers often results in lower costs compared to natural materials, making products more accessible. Innovation in Medicine: Polymers are crucial in medical applications, such as drug delivery systems, implants, and biodegradable sutures, improving healthcare outcomes.
3. Environmental Impact: Negative Impacts: Plastic Pollution: Synthetic polymers, particularly plastics, contribute to global pollution. They can take hundreds of years to decompose, leading to accumulation in landfills, oceans, and natural habitats. Wildlife Threats : Marine and terrestrial animals can ingest or become entangled in plastic waste, leading to injury or death. Microplastics can Positive Aspects : Biodegradable Options : Advances in material science have led to the development of biodegradable and compostable synthetic polymers that can mitigate some environmental impacts. Recycling Innovations : Improved recycling technologies and programs aim to recover and reuse synthetic polymers, reducing waste and resource consumption. also enter the food chain, posing risks to wildlife and human health.
Teflon: Equipment Coatings: Nonstick Surfaces : Teflon-coated surfaces are used in mixing and processing equipment to prevent material from sticking, which helps ensure uniform mixing and easier cleaning. Reaction Vessels: Coating the insides of reactors with Teflon can prevent corrosion and contamination, allowing for safer chemical reactions . Drug Delivery Systems: Implants and Devices : Teflon is used in some drug delivery systems and medical devices due to its biocompatibility and low friction properties. Reservoirs : PTFE can be used as a reservoir material in implantable devices that deliver medication over time. Surgical Instruments: Coated Instruments : Some surgical instruments are coated with Teflon to enhance their nonstick properties, reducing tissue adhesion during surgeries.
