Hybrid material. Hybrid materials are composites consisting of two constituents at the nanometer or molecular level. Commonly one of these compounds is inorganic and the other one organic in nature. Thus, they differ from traditional composites where the constituents are at the macroscopic (micrometer to millimeter) level.
Synthesis means that something is put together, and synthetic materials are made of building blocks that are put together in factories. The building blocks for making plastics are small organic molecules-molecules that contain carbon along with other substances.hen you polymerize ethylene you get a polyethylene resin. There are a number of polyethylene resins families that differ by such properties as density and molecular weight, and they can be made into a huge variety of plastic products. One of the most common is the plastic grocery bag.
