Abstract

Disclosed herein is a multilayered tape comprising a first layer; where the first layer comprises a first surface and second surface; the first surface of the first layer having a surface texture; a second layer; the second layer having a first surface and a second surface; where the first surface of the second layer is closer to the second surface of the first layer than the second surface of the second layer; where the second surface of the second layer contains at least one partition that is parallel to a longitudinal direction of the multilayered tape.

First claim

What is claimed is:

1. A multilayered tape comprising:
a first layer; where the first layer comprises a first surface and second surface; the first surface of the first layer having a surface texture;
a second layer; the second layer having a first surface and a second surface; where the first surface of the second layer is closer to the second surface of the first layer than the second surface of the second layer; where the second surface of the second layer contains a plurality of slits that are parallel to a longitudinal direction of the multilayered tape and are operative to expand when the tape contacts a surface to which it imparts the surface texture.

2. The multilayered tape of claim 1 , further comprising a third layer disposed between the first layer and the second layer where the third layer is operative to bond the first layer to the second layer.

3. The multilayered tape of claim 1 , where the first layer has a lower softening temperature than the second layer.

4. The multilayered tape of claim 1 , where the first layer has a softening temperature of greater than 130° C. and where the second layer has a softening temperature greater than 200° C.

5. The multilayered tape of claim 1 , where the first layer comprises a polycarbonate and where the second layer comprises a polyimide.

6. The multilayered tape of claim 1 , where the first layer comprises a polycarbonate and where the second layer comprises a metal or a ceramic.

7. The multilayered tape of claim 2 , where the third layer comprises a silicone adhesive, an acrylate, an epoxy, or a combination thereof.

8. The multilayered tape of claim 1 , where the third layer comprises a silicone adhesive.

9. The multilayered tape of claim 1 , where the surface texture comprises a plurality of patterns; each pattern being defined by a plurality of spaced apart features; the plurality of features each having at least one neighboring feature having a substantially different geometry, wherein an average spacing between adjacent spaced apart features is about 1 nanometer to about 1 millimeter in at least a portion of the surface texture, wherein the plurality of spaced apart features are represented by a periodic function.

10. The multilayered tape of claim 1 , where an end of the multilayered tape in the width direction is beveled.

11. The multilayered tape of claim 2 , where the third layer is crosslinked.

12. A method comprising:
disposing a first layer on a second layer to form a multilayered tape; where the first layer comprises a first surface and second surface; the first surface of the first layer having a surface texture; and where the second layer comprises a first surface and a second surface; where the first surface of the second layer is closer to the second surface of the first layer than the second surface of the second layer; where the second surface of the second layer contains a plurality of slits that are parallel to a longitudinal direction of the multilayered tape and are operative to expand when the tape contacts a surface to which it imparts the surface texture; and
bonding the first layer to the second layer.

13. The method of claim 12 , further comprising disposing a third layer between the first layer and the second layer.

14. A method comprising:
contacting a device with a multilayered tape, where the multilayered tape comprises:
a first layer; where the first layer comprises a first surface and second surface; the first surface of the first layer having a surface texture;
a second layer; the second layer having a first surface and a second surface; where the first surface of the second layer is closer to the second surface of the first layer than the second surface of the second layer; where the second surface of the second layer contains a plurality of slits that are parallel to a longitudinal direction of the multilayered tape and are operative to expand when the tape contacts a surface to which it imparts the surface texture;
transporting the device and a multilayered tape through a guide tube; the multilayered tape being disposed on an outer surface of a conduit, where the multilayered tape is placed between the conduit and the guide tube; where a longitudinal axis of the tape is substantially parallel to a longitudinal axis of the device; and
transferring a texture from the multilayered tape to the device as the device and the multilayer tape are transported through the guide tube.

15. The method of claim 14 where the device is a cylinder or a conduit having a circular cross-section.

16. The multilayered tape of claim 1 , where the multilayered tape comprises two surface ends that are beveled such that one surface end can slip under the other surface end to prevent any overlap.

17. The method of claim 12 , where the multilayered tape comprises two surface ends that are beveled such that one surface end can slip under the other surface end to prevent any overlap.

18. The method of claim 14 , where the multilayered tape comprises two surface ends that are beveled such that one surface end can slip under the other surface end to prevent any overlap.
