Foams consist of a liquid or solid through which a [[gas]] has been dispersed to form cavities.  This structure imparts a large [[surface-area-to-volume ratio]] on the system.<ref name=":10" /><ref name=":12">{{Cite journal |last1=Jin |first1=Fan-Long |last2=Zhao |first2=Miao |last3=Park |first3=Mira |last4=Park |first4=Soo-Jin |date=2019 |title=Recent Trends of Foaming in Polymer Processing: A Review |journal=Polymers |language=en |volume=11 |issue=6 |pages=953 |doi=10.3390/polym11060953 |issn=2073-4360 |pmc=6631771 |pmid=31159423|doi-access=free }}</ref> Foams have found applications in [[Thermal insulation|insulation]] and [[Textile|textiles]],<ref name=":12" /> and are undergoing active research in the biomedical field of drug delivery and [[tissue engineering]].<ref name=":11" />  Foams are also used in automotive for water and dust sealing and noise reduction.
