Here, we demonstrate multifunctional activity of a polydimethyl siloxane (PDMS) nanocomposite sponge for microbial mitigation and oil contaminant removal from water. Different concentrations of silver (Ag) nanoparticles have been studied for their anti-microbial activity along with activated Carbon (AC). Further, AC and Ag nanoparticles were incorporated inside the PDMS sponge using a unique non-aqueous in-situ reduction synthesis method to generate a nanocomposite sponge thus, rendering a hierarchical (i.e. micropores decorated with nanoparticles) texture on the sponge. The as-grown sponges were tested for their physico-chemical characteristics along with features including anti-microbial activity as well as absorption of floating-oil contaminants from water.

智能多任务PDMS纳米复合海绵,用于去除水中的微生物和油污

在这里,我们展示了聚二甲基硅氧烷(PDMS)纳米复合海绵的多功能活性,用于缓解微生物和从水中去除油污。已经研究了不同浓度的银(Ag)纳米颗粒与活性炭(AC)的抗微生物活性。此外,使用独特的非水原位还原合成方法,将AC和Ag纳米颗粒掺入PDMS海绵内部,以生成纳米复合海绵,从而在海绵上呈现出分层的纹理(即装饰有纳米颗粒的微孔)。对生长中的海绵进行了理化特性测试,包括抗菌活性以及从水中吸收浮油污染物的功能。
