Abstract
Articles and methods related to multilayered media are generally provided. Some embodiments are generally related to filter media. Some embodiments relate to multilayered media comprising an irregular structure. The irregular structure may be present on an external surface of the multilayered media, in the interior of the multilayered media, and/or throughout the multilayered media. Some aspects are generally related to multilayered media that are reversibly stretchable and/or comprising a polymeric film.
Claims25
A reversibly stretchable multilayered media, the media comprising:
- a first layer having an average surface height of greater than or equal to 0.3 mm and having an undulated configuration;
- a second layer adjacent the first layer, the second layer having the undulated configuration;
- a third layer adjacent the first layer, the third layer having the undulated configuration;
- and
- a fourth layer adjacent the third layer,
- wherein the first layer comprises:
- a first substrate;
- a second substate;
- and
- a polymeric film disposed between the first substrate and the second substrate.
A multilayered media, the media comprising:
- a first layer having an average surface height of greater than or equal to 0.3 mm and having an undulated configuration;
- a second layer adjacent the first layer;
- a third layer adjacent the first layer, the third layer having the undulated configuration;
- and
- a fourth layer adjacent the third layer,
- wherein the first layer comprises:
- a first substrate;
- a second substate;
- and
- a polymeric film disposed between the first substrate and the second substrate.
A multilayered media, comprising:
- a first layer adjacent a second elastomeric layer, the first layer comprising a first substrate, a second substrate, and a polymeric film disposed between the first substrate and the second substrate, the first layer having a plurality of peaks having a first average peak spacing and a first peak spacing standard deviation;
- and
- a third layer deposited on the first layer,
- wherein the third layer comprises a plurality of peaks having a second average peak spacing and a second peak spacing standard deviation,
- wherein the first average peak spacing and the second average peak spacing are the same or different.
