| 摘 要： | 利用火焰喷涂法制备了尼龙1010(PA1010)/n-ZrO2复合涂层,采用差示扫描量热法(DSC)对复合涂层的非等温结晶过程、熔融行为进行了分析.结果表明,纳米ZrO2粒子的加入不仅能提高复合涂层的结晶速率和结晶温度,而且使复合涂层的熔融峰肩峰的熔融温度高于纯PA1010涂层.结论:纳米ZrO2粒子具有成核剂的作用,诱导尼龙大分子结晶,使其结晶能力及结晶的完善程度提高. |

| Abstract: | Polyamide 1010(PA1010)/nano-ZrO2 composite coating was prepared by flame sprayed.The processes of non-isothermal crystallization,the melt behavior of PA1010/nano-ZrO2 composite coatings were investigated by differential scanning calorimeter(DSC).The experimental results show that the crystallization temperature of PA1010/nano-ZrO2 composite coating increases due to the heterogeneous nucleation of nano-ZrO2 particles compared with pure PA1010 coating.A phenomenon of dual melting peaks appears during the melting process of pure PA1010 and PA1010/nano-ZrO2 composite coating.And the low melt peak temperature of the PA1010/nano-ZrO2 composite coating increases obviously as a result of the addition of nano-ZrO2 particles.Meanwhile,nano-ZrO2 particles act as a nucleation agents in the PA1010 matrix. |
