Abstract
An adhesive composite is provided that may include a substrate and an adhesive layer overlying the substrate. The adhesive layer may include at least a first region of a high Tg adhesive material and a second region of a low Tg adhesive material. The first region of the adhesive layer may be co-planar with the second region of the adhesive layer. The high Tg adhesive material may include a first glass transition temperature Tg1 and the low Tg adhesive material may include a second glass transition temperature Tg2, where Tg1 is greater than Tg2.
