Thermoplastic elastomers (TPEs) are generally entropic networks with micro-phase separated morphology.They are made of flexible chain segments which impart elastic properties and physical crosslinks which connect flexible chain segments together upon acting as knots.One prominent weakness of TPEs is the lower elasticity and higher permanent set compared to rubbers (thermosets), because the physical interactions among physical crosslinks are relatively weak and easily be broken under external stresses.Many attempts have been made to further strengthen physical interactions so as to reduce permanent set.However, physical interactions remain inherently weak.

氮氧化物(NOx)是大气污染的主要有害物质之一,氮氧化物有N2O、NO、NO2、N2O3、N2O4和N2O5,总称为NOx,其中污染大气的主要氮氧化物是NO和NO2.大气中的氮氧化物是形成酸雨酸雾的主要污染物,同时破坏臭氧层,形成光化学烟雾,对人体具有致毒作用.因此,在燃烧过程中,必须对氮氧化物的排放进行严格控制.2015年1月1日开始执行的国家标准《炼焦化学工业污染物排放标准》对大气污染物NOx
