The severity of the current global pandemic (COVID-19) had not only affected human health but also the worlds economy, social interaction and environment. To regulate the virus transmittance, face mask are used as a precursionary aid of protection from the virus. Thus, heightening the production and consumption of face mask which generates tons of plastic wastes. Therefore, transformation of value-added products from this enormous waste is imperative to provide a sustainable approach for the modulation of these waste plastics. Herein, a one-pot synthesis method was presented to fabricate a dual-pore network from polypropylene mask filters intercalated by calcium alginate through ice templating method generating a dual-pore aerogel composite (c-CA-PP) for effective and broadband frequency sound absorption, thermal insulation and flame retardancy. |
