Polyamides
Mandarin:
聚酰胺 (jù xiān àn)
聚酰胺 (jù xiān àn)
Explanation in English Language (EN):
Polyamides are a class of polymers that contain amide linkages (-CO-NH-) in their backbone. These linkages are formed by the reaction of a carboxylic acid group (-COOH) with an amine group (-NH2). Polyamides are known for their high strength, toughness, and resistance to abrasion and chemicals. Nylon is a well-known example of a polyamide.

Explanation in Mandarin (ZH):
聚酰胺是一类在其主链中含有酰胺键 (-CO-NH-) 的聚合物。这些键是通过羧酸基团 (-COOH) 与胺基团 (-NH2) 反应形成的。聚酰胺以其高强度、韧性以及耐磨性和耐化学性而闻名。尼龙是聚酰胺的一个众所周知的例子。
