摘要
采用液相剥离技术对黑磷和氧化石墨烯进行分散,通过共价键作用制得BP-GO复合载体,经氧化还原反应在BP-GO复合载体表面原位还原AgNPs。探究了硝酸银含量、BP-GO含量比值对复合粉体性能的影响,对比分析了相同条件下制备的BP-GO-AgNPs与GO-AgNPs复合涂层的抑菌性能。利用SEM、TEM分析表明,BP与GO成功分散,且BP-GO载体成功复合,同时AgNPs成功负载在载体表面,较优的AgNO_(3)添加量为3×10^(-4) mol。XPS分析表明,BP与GO纳米片通过P-C、P-O-C的键合作用力联接,且AgNPs成功负载在载体表面,成功制得BP-GO-AgNPs复合粉体。Raman分析表明,复合粉体中BP-GO含量较优比值为1:1。抑菌结果表明,相同条件下,BP-GO-AgNPs复合涂层相较于GO-AgNPs复合涂层的抑菌效果更好。
The BP and GO were dispersed by liquid-phase stripping technique.BP-GO composite carrier was prepared by covalent bonding.AgNPs were reduced in situ on the surface of BP-GO composite carrier by redox method.The effects of silver nitrate content and BP-GO content ratio on the properties of composite powders were investigated,and the antibacterial properties of BP-GO-AgNPs and GO-AgNPs composite coatings prepared under the same conditions were compared and analyzed.SEM and TEM analysis results show that BP and GO are successfully dispersed,BP-GO carrier is successfully combined,and AgNPs are successfully loaded on the carrier surface,with the optimal AgNO_(3) dosage parameter of 3×10^(-4)mol.XPS analysis shows that BP-GO-AgNPs composite powders are successfully prepared by the joint of P-C and P-O-C,and the AgNPs are successfully loaded on the surface of the carrier.Raman analysis shows that the optimal ratio of BP-GO content in the composite powder is 1:1.The antibacterial results show that the BP-GO-AgNPs composite coating has better antibacterial effect than the GO-AgNPs composite coating under the same conditions.
