    • An in situ process for preparing a phase change magnetic ink including combining a phase change ink composition with a reducing agent; wherein the phase change ink composition comprises a carrier, an optional colorant, and an optional dispersant, and wherein the reducing agent has at least one alcohol functionality; heating the combined phase ink composition and reducing agent to a first temperature sufficient to provide a melt composition; adding a metal salt to the melt composition under an inert atmosphere to provide a metal salt-melt composition; heating the metal salt-melt composition to a second temperature sufficient to effect a metal reduction reaction to reduce the metal salt to metal nanoparticles thus forming in situ a phase change magnetic ink including the metal nanoparticles; optionally, filtering the phase change magnetic ink while in a liquid state; cooling the phase change magnetic ink to a solid state.
    • 一种用于制备相变磁性油墨的原位方法,包括将相变油墨组合物与还原剂组合; 其中所述相变油墨组合物包含载体,任选的着色剂和任选的分散剂,并且其中所述还原剂具有至少一种醇官能团; 将组合相油墨组合物和还原剂加热到足以提供熔体组合物的第一温度; 在惰性气氛下向熔融组合物中加入金属盐以提供金属盐 - 熔融组合物; 将金属盐熔体组合物加热到足以进行金属还原反应的第二温度以将金属盐还原成金属纳米颗粒,从而原位形成包括金属纳米颗粒的相变磁性油墨; 可选地,在液态的情况下过滤相变磁性墨; 将相变磁性墨水冷却至固态。
