摘要：
An article comprising a double-switching heater that comprises a double-switching PTC ink deposited on a flexible substrate to form one or more resistors. The double-switching PTC ink comprises a first resin and a second resin; the first resin provides a first PTC effect within a first temperature range (T1, T2); the second resin provides a second PTC effect within a second temperature range (T3, T4), where T3≥T2; the first resin has an NTC effect above the first temperature range; the second PTC effect is greater than the first PTC effect; and the second PTC effect overlaps with, and is greater than, the NTC effect of the first resin. The substrate can be either thermal polyurethane, nylon or a polyester blend.
