Three triggers result in two measurable outputs from polymeric sensors: multiresponsive polyampholytic graft copolymers respond to pH‐value and temperature, as well as the type and concentration of metal cations and therefore, allow the transformation of external triggers into simply measurable outputs (cloud point temperature (T_CP) and surface plasmon resonance (SPR) of encapsulated silver nanoparticles). The synthesis relies on poly(dehydroalanine) (PDha) as the reactive backbone and gives straightforward access to materials with tunable composition and output. In particular, a rather high sensitivity toward the presence of Cu²⁺, Co²⁺, and Pb²⁺ metal cations is found.

具有多种输出的三响应式多磷酸接枝共聚物作为智能传感器

三种触发条件可导致聚合物传感器产生两个可测量的输出：多响应多两性接枝共聚物可响应pH值和温度以及金属阳离子的类型和浓度，因此可将外部触发条件转换为简单可测量的输出（浊点温度）（T _CP）和包封的银纳米颗粒的表面等离子共振（SPR））。该合成依赖于聚（脱氢丙氨酸）（PDha）作为反应性主链，可以直接获得具有可调组成和产量的材料。特别地，发现对于Cu 2 ⁺，Co ²⁺和Pb ²⁺金属阳离子的存在相当高的敏感性。
