Thoroughly updated, Introduction to Polymers, Third Edition presents the science underpinning the synthesis, characterization and properties of polymers. The material has been completely reorganized and expanded to include important new topics and provide a coherent platform for teaching and learning the fun...
addition(加成)carothers originally classified polymers based on a comparison of the atoms in the monom 25、er to the atoms in the repeat unit. addition polymerization (加成聚合)(加成聚合)polymer has the same atoms as their monomers condensation polymerization (缩合聚合)(缩合聚合)polymer has fewer...
The spinning of a mixture of two separate polymers is another way of creating porous nanofibers. 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 ...
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...
• 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 ...

In discussing bioplastics and biodegrading, it is important to draw clear distinctions between the terms. Work by Vert [11] sets out clear definitions around the areas of bio-related polymers. Bioploymer are polymeric materials, the precursors of which are derived from biomass sources (as tested...
