9、s are large molecules.Fortunately,they are not random collections of atoms;if this were the case,they would be impossible to study.Polymers are built up from smaller molecules(monomers),and therefore possess a characteristic chain structure consisting of multiple repeat units that are related che...

Some of the polymers are extracted by degradation in a solvent during fibre forming, under which the other polymers become insoluble. As repulsive charges extend the solution, the electrospinning jet route is very disorderly and only unwoven meshes are generated with traditional installations. ...
3. Laser-Based Bioprinting Stereolithography (SLA) is an AM technique that uses ultraviolet (UV) or visible light to cure photosensitive polymers in a layer-by-layer fashion, as shown in Figure 3. This nozzle-free technique eliminates the negative effects of shear pressure e...
In both filaments and slit films, the extrusion or drawing process elongates the polymers in the direction of the draw and increases in the filament strength. Geotextile type is detennined by the method used to combine the filaments or tapes into the planar structure. The vast majority of ...

• Pocan is the trade name of Lanxess for its thermoplastic polyesters based on Polybutylene Terephthalate (PBT) z Polyamide and Polybutylene Terephthalate belong to semi-crystalline polymers offering an excellent combination of mechanical and electrical properties coupled with good resistance to heat ...
Polymers may dissolve when exposed to a liquid solvent, or they may absorb the solvent and swell; also, electromagnetic radiation (primarily ultraviolet) and heat may cause alterations in their molecular structures. The deterioration of each of these material types is discussed in this chapter, ...
