- Abstract
- In order to enhance the surface properties of the architectural material we manufactured a submicro-silver solution, and carried out several functional tests for its dispersity, antibiotic action, and abrasion. Fully dispersed submicro-silver solutions were optimally obtained through a reductive reaction including NaBH_4 (5 mM) and Tween20 (1wt%). SDS and overdose of PVP as stabilizers resulted in poor quality of Ag suspension. The silver suspension whose concentration was 600 ppm or more could extinguished more than 99.5% of the test bacteria whereas sterilizing efficiency of the powder silver was only 50%. The coated layer formed by spreading the silver suspension with a binder was firmly adhered onto gypsum surfaces. Scratch and ink tests were also found to be successful for the material.
