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.

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。
