Bio-plastics are the environmental friendly plastics derived from the renewable biomass
sources such as vegetable oil and com-starch. Find out more about them and their uses.
Answers
Bioplastics are plastic materials produced from renewable biomass sources, such as vegetable fats and oils, corn starch, straw, woodchips, sawdust, recycled food waste, etc. Bioplastic can be made from agricultural by-products and also from used plastic bottles and other containers using microorganisms.
plastic composites generally comprise two components: a reinforcement fiber and a polymer binder (often called a matrix). Green Building Solutions! about 3 years ago. "Vinyl products can be rigid or flexible based on how they're made.
Nanocomposites are materials that incorporate nanosized particles into a matrix of standard material. The result of the addition of nanoparticles is a drastic improvement in properties that can include mechanical strength, toughness and electrical or thermal conductivity.
Self-healing materials are artificial or synthetically-created substances which have the built-in ability to automatically repair damages to themselves without any external diagnosis of the problem or human intervention. Generally, materials will degrade over time due to fatigue, environmental conditions, or damage incurred during operation. cracks and other types of damage on a microscopic level have been shown to change thermal, electrical, and acoustical properties of materials, and the propagation of cracks can lead to eventual failure of the material. In general, cracks are hard to detect at an early stage, and manual intervention is required for periodic inspections and repairs. In contrast, self-healing materials counter degradation through the initiation of a repair mechanism which responds to the micro-damage. some self-healing materials are classed as smart structures, and can adapt to various environmental conditions according to their sensing and actuation properties.
Plastic electronics is a concept that emerged forty years ago, with the discovery of electrically conductive polymers. Ten years later, the first electronic devices using organic solids in place of the ubiquitous inorganic semiconductors.
smart polymers exist with a variety of properties depending on reactive functional groups and side chains. These groups might be responsive to pH, temperature, ionic strength, electric or magnetic fields, and light. ... Traditional drug encapsulation has been done using lactic acid polymers.
