Articles having conformal layers and methods of making same

A method of making an article, the method comprising:

• obtaining a tool comprising protruding features;
• disposing a first polymer on the protruding features;
• disposing a second polymer on the first polymer;
• applying compression to the tool, the first polymer, and the second polymer at an elevated temperature to form the article, wherein the second polymer forms a first polymeric layer of the article and the first polymer forms a second polymeric layer of the article;
• disposing a third layer on the second polymeric layer, the first major surface being in contact with the second polymeric layer;
• applying compression to the second polymeric layer at an elevated temperature to bond the second polymeric layer to the third layer;
• wherein the article comprises:
• a first polymeric layer having a first major surface that is substantially planar and an opposing second major surface;
• a second polymeric layer bonded to the first polymeric layer, the second polymeric layer having a first major surface and a second major surface, wherein the first major surface of the second polymeric layer is conformal to the second major surface of the first polymeric layer, wherein the second major surface of the second polymeric layer defines a cavity comprising at least one wall, and
• a channel having an inlet at the cavity and an outlet on an edge of the second polymeric layer at a location remote from the cavity or on the first major surface of the first polymeric layer,
• wherein the second polymeric layer has a Vicat softening temperature (Tg) of 100 degrees Celsius (° C.) or less,
• and wherein a surface of the cavity exhibits an advancing contact angle with water of less than 90 degrees;
• and
• a third layer bonded to the second polymeric layer, wherein a surface of the third layer and the cavity of the second polymeric layer together define a chamber.
