POLYMERS
Chemical structure
Polymers are made up of many monomers, which are linked together to form linear chains.
E.g: polyethylene, cellulose, ...
-
Polymer chains can be linked together by atoms or groups of atoms, forming crosslinked polymers.
E.g: Rubberization
Plastics
-
durable, lightweight, non-conductive, poor heat conductors, waterproof, ...
Plastics are flammable, have limited strength, ... therefore, when using them, avoid direct contact with fire and limit strong impacts that cause deformation, ...
Rubber
-
At excessively high temperatures, rubber will melt; at excessively low temperatures, rubber will lose its elasticity (becoming brittle and hard)
-
Types of Polymers
Natural polymers: Silkworm fibers, Cellulose (hemp fibers, cotton, etc.), starch (wheat, flour, etc.).
Synthetic polymers: Polyethylene (PE), Polypropylene (PP), etc.
Composite materials
Mental compositive is a material that is made up of two or more different materials, including the core material and the base material.
The core material plays a role in enhancing the mechanical properties of the material, usually in the form of fibers and granular. Base materials are usually materials with high plasticity
Silk
Silk is used to weave garments, tire lining fabrics, sock weaving, braiding into cables, and weaving nets,... some types of silk (silk, nylon silk) are used to weave garments.
silk has different properties, so when washing and ironing, it is necessary to pay attention to the manufacturer's instructions to choose the appropriate washing, ironing and detergent mode.
Properties
Most polymers are solid, non-volatile, insoluble in water, some can be soluble in gasoline (eg: Polystyrene (PS), Polyisoprene,...).
A polymer is a large molecule or a macromolecule of organic matters, which essentially is a combination of many subunits
