The importance of indoor air quality issues has become increasingly important in recent years because most of the population in industrialised countries spends up to 90% of their time in confined environments. International scientific literature has shown that indoor air quality (IAQ) has important effects on human health and well-being. The main contributors to pollution to indoor air pollution include Particulate Matter (PM) and gaseous pollutants such as volatile organic compounds (VOCs) or nitrogen oxides (NOX), which represent a considerable problem both for the environment and for human beings. Consequently, it is essential to act at the root of the problem by reducing the origin of indoor air pollutants as much as possible, particularly those of anthropogenic origin, but also by identifying filtration systems that improve the IAQ. This review presents an overview of the electrospinning process and the characterisation of nanofibres, illustrating the technologies and materials used in the development of innovative filters.

L’importanza delle problematiche relative alla qualità dell’aria interna ha assunto sempre più rilievo in questi ultimi anni perché la maggior parte della popolazione dei paesi industrializzati trascorre fino al 90% del proprio tempo in ambienti confinati. La letteratura scientifica internazionale ha dimostrato che la qualità dell’aria interna (IAQ – Indoor Air Quality) ha riflessi importanti sulla salute e sul benessere umano. I principali contribuenti all'inquinamento dell'aria interna includono il Particolato (PM – Particulate Matter) e gli inquinanti gassosi come i composti organici volatili (COV) o gli ossidi di azoto (NOX), che rappresentano un problema considerevole sia per l'ambiente che per gli esseri umani. Di conseguenza è fondamentale agire alla radice del problema riducendo al massimo l'origine degli inquinanti dell'aria interna, in particolare quelli di origine antropica, ma anche identificando sistemi di filtraggio che migliorano il IAQ. Questa rassegna presenta una panoramica del processo di elettrofilatura e della caratterizzazione delle nanofibre, illustrando le tecnologie e i materiali impiegati per lo sviluppo di filtri innovativi. Vengono inoltre trattati i temi della gestione degli inquinanti gassosi, quali ossidi di azoto e composti organici volatili, con particolare attenzione alle tecnologie applicate e ai metodi sperimentali utilizzati per la loro analisi.

Abstract
The importance of indoor air quality issues has become increasingly important in recent years because most of the population in industrialised countries spends up to 90% of their time in confined environments. International scientific literature has shown that indoor air quality (IAQ) has important effects on human health and well-being. The main contributors to pollution to indoor air pollution include Particulate Matter (PM) and gaseous pollutants such as volatile organic compounds (VOCs) or nitrogen oxides (NOX), which represent a considerable problem both for the environment and for human beings. Consequently, it is essential to act at the root of the problem by reducing the origin of indoor air pollutants as much as possible, particularly those of anthropogenic origin, but also by identifying filtration systems that improve the IAQ. This review presents an overview of the electrospinning process and the characterisation of nanofibres, illustrating the technologies and materials used in the development of innovative filters. It also covers the topics of management of gaseous pollutants such as nitrogen oxides and volatile organic compounds, with a focus on applied technologies and experimental methods used for their analysis experimental methods used for their analysis.File | Dimensione | Formato | |
