| Abstract: |
| This paper aims at synthesizing a detergent with graphene oxide (GO) and lauryl betaine (LB), where the GO will have a better performance with the modification of LB. First, the complexus of GO and LB and the complexus of GO, KH550 (Amino functional silane), and LB were synthesized to obtain two products, GO-LB and GO-KH550-LB. Then, the abilities and safety of the products were evaluated by characterization, contact angle measurement, measurement of KRAFFT Point, foaming test, emulsion ability test, decontamination capacity test, skin irritation test, and skin allergy test. Results of the experiment showed that GO-LB was superior to GO-KH550-LB in wetting ability and foaming stability, while GO-KH550-LB outperformed in emulsifying capacity. Besides, good abilities of removing mussels, seaweed, and protein were proved. According to the result of the irritation test of the materials to skin, they were both at the light irritation level, and the irritation of the GO-LB was slightly lower than that of GO-KH550-LB. Neither GO-LB nor GO-KH550-LB had allergic effect. Therefore, it can be concluded that as a surface active agent, graphene oxide/lauryl betaine was effective as a new detergent, which had low irritation and insignificant allergic phenomena on the human body over a long term of use. |

| 本论文以氧化石墨烯（GO）和十二烷基甜菜碱（LB）为原料合成洗涤剂。通过对LB的改性，得到了GO-LB和GO-KH550（氨基官能团硅烷）和LB的配合物，得到了GO-LB和GO-KH550-LB两种产品，并通过表征、成分分析等方法对其性能和安全性进行了评价。t角测量、krafft点测量、发泡试验、乳液能力试验、去污能力试验、皮肤刺激试验、皮肤过敏试验。实验结果表明，Go-KH550-LB在润湿性和发泡稳定性方面优于Go-KH550-LB，在乳化性方面优于A。并证明了其去除贻贝、海藻和蛋白质的能力。根据两种材料对皮肤的刺激性试验结果，它们都处于轻度刺激水平，Go-LB的刺激性略低于Go-KH550-LB，Go-LB和Go-KH550-LB均无过敏作用。因此，作为一种表面活性剂，我们可以得出结论：氧化石墨烯/十二烷基甜菜碱作为一种新型洗涤剂是有效的，长期使用对人体刺激性低，过敏现象不明显。 |
