1、结构
聚合材料的结构要记清,bingo,基于碳链的重复结构。a repeating structure, usually based on a carbon backbone.
2、特点
聚合材料的特点还是很明显的lightweight,corrosion resistant, easy to process at low temperatures and generally inexpensive.
3、工业特性
如果问及聚合材料的工业characteristics,无非就是their size (or molecular weight), softening and melting points, crystallinity, and structure. The mechanical properties of polymers generally include low strength and high toughness.
4、特别的问题
当然也会有比较奇怪的问题比如如何加强聚合材料的强度,一句话,加强复合结构就成。(reinforced composite structures)
要注意的是polymor聚合物可以是晶体状的或非结晶质的,但它们通常是晶体状和非结晶质结构的结合物。
