Study on Preparation and Performance of Nano-Silver/Silicone Sealant
This study successfully synthesized nano-silver particles by hydrothermal synthesis,and then prepared the nano-silver/silicone sealant by physical blending with polydimethylsiloxane as the matrix of silicone oil.The microstructural mor-phology,thermal resistance,mechanical properties,and antibacterial property of the nano-silver/silicone sealant were investiga-ted.The results show that the prepared sealant exhibits excellent tensile strength(4.22 MPa)and elongation at break as high as 157.1%when the nano-silver is 10wt%.Besides,the sealant has outstanding antibacterial performance,and it still has good an-tibacterial effect and excellent durability,even after being placed at room temperature for 40 days.It provides a new approach for green,healthy,and clean sealing applications.
