摘　　要：用氧化石墨烯(GO)与铬鞣剂复配得到GO与铬鞣剂配合物.鞣制试验发现,少量GO的参与能够明显地提高铬鞣剂的鞣制效果和吸收率.在铬鞣剂用量以Cr_2O_3计量为0.5%且GO用量为0.020%时,鞣制皮革的收缩温度可以达到90℃以上;Cr_2O_3用量为1%且GO用量为0.030%时,鞣制皮革的收缩温度可以达到100℃以上,铬鞣剂的吸收率达到了98%.与纯铬鞣相比较,GO与铬鞣剂配合物鞣剂具有用量少、对环境污染小、鞣制皮革性能好的特点.The complex of graphene oxide （GO）‐chrome tanning agent was prepared using GO and chrome tanning agent .The tanned results indicated that mixing a little GO into the com‐plex can significantly improving tanning effects and adsorption rate of chrome tanning agent . When chrome agent dosage is 0 .5% and GO is 0 .020% ,the shrinkage temperature （Ts） of the tanned leather can reach 90 ℃ .While chrome tanning agent dosage is 1 .0% Cr2 O3 and the GO is 0 .020% ,the Ts of the tanned leather can reach over 100 ℃ and adsorption rate of chrome tanning agent can reach 98% .Compared with chrome tanning alone ,GO‐chrome tan‐ning agent complex has features of less dosage and pollution as well as excellent properties of tanned leather .
