Elastomeric Nanocomposites Based on Sol-Gel Reactions of Silicon Alkoxides in Ionomeric Derivatives of Finely-Architectured Block Copolymers

摘要

The goal of the proposed research is lightweight elastomers to be used in clothing that protects soldiers from chemical warfare agents (CWAs). Outward transport of water from perspiration is another important requirement. Our approach addresses the simultaneous fulfillment of these requirements through the manipulation of the heterogeneous architecture, followed by the inorganic modification of hard/soft block copolymer (BCP) elastomers. An inorganic component is inserted within the sulfonated hard block domains in block copolymer ionomers (BCPIs) via in situ sol-gel reactions for hydrolyzed silicon alkoxides.
