摘　　要：将经过不同酸化方式纯化和改性的多壁碳纳米管与铬粉以不同方式进行共混,研究经碳纳米管改性后铬鞣剂的鞣革性能,并对革中三氧化二铬的含量、鞣后革样厚度的增加、收缩温度、抗张强度等性能进行了比较。结果表明:与纯铬粉相比,经碳纳米管改性的铬粉鞣制革样的增厚率和革中三氧化二铬的含量、革的崩破高度明显增加,革样的收缩温度有一定提高,而抗张强度、撕裂强度变化不大。The tanning properties of chrome tanning agent were investigated, which modified by multi - walled carbon nanotubes purified and modified by the different acid in a different ways. The changes of shrinkage temperature, thickness, trioxide chrome content in the leather and the physical performance after tanning were compared. Results show that, the thickness and trioxide chrome content and bursting height of the leather tanned by chrome which modified by multi - wailed carbon nanotubes increases significantly compared with that of the leather tanned by pure chrome. The shrinkage temperature is improved. The changes of tear strength and tensile strength are not obvious.
