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Cr2 O3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;Cr2 O3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.
用氧化石墨烯(GO)與鉻鞣劑複配得到GO與鉻鞣劑配閤物.鞣製試驗髮現,少量GO的參與能夠明顯地提高鉻鞣劑的鞣製效果和吸收率.在鉻鞣劑用量以Cr2 O3計量為0.5%且GO用量為0.020%時,鞣製皮革的收縮溫度可以達到90℃以上;Cr2 O3用量為1%且GO用量為0.030%時,鞣製皮革的收縮溫度可以達到100℃以上,鉻鞣劑的吸收率達到瞭98%.與純鉻鞣相比較,GO與鉻鞣劑配閤物鞣劑具有用量少、對環境汙染小、鞣製皮革性能好的特點.

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 .
