臭氧老化作用对SY-1硅橡胶机械性能的影响

目的 :评估臭氧老化作用对SY 1硅橡胶物理性能、机械性能的影响。方法 :按国家标准要求对SY 1硅橡胶臭氧老化前后硬度 (邵氏 A)、扯断强度、扯断伸长率和撕裂强度进行测试 ,并进行统计学分析。结果 :经臭氧老化作用处理 ,硬度差异显著 (P =0 .0 0 82 ) ,扯断强度、扯断伸长率、永久变形和撕裂强度老化前后无显著差异 (P >0 .0 5 )。结论 :SY 1硅橡胶物理机械性能优良 ,同时具有良好的抗臭氧老化性能。

Molecular uniting set identified characteristic(MUSIC): a promising strategy for purely organic RTP luminogens

The room temperature phosphorescences（RTP）are of growing interest owing to their promising applications in material science and bioimaging.To date,the lumiogens showing persistent RTP effect mainly contain the noble metals which have the shortcomings such as high cost,potential toxicity.The exploration of metal free luminogens,i.e.,purely organic RTP luminogens,is thus of great importance for the community.
