Study on the effect of CMC/HNTs/MSN coatings on the performance of thermal transfer paper

With the continuous growth of the inkjet printing market, it has become particulary important to endow dye thermal transfer paper with fast-drying performance and fine transfer effect. In order to achieve this goal, the nanohybrid materials of HNTs/MSN (halloysite nanotubes/mesoporous silica) were prepared by Stöber method and in situ growth method, and then, the thermal sublimation transfer papers coated with CMC/MSN, CMC/HNTs, and CMC/HNTs/MSN were prepared, respectively. Characterizations of MSN, HNTs, and HNTs/MSN were conducted using TEM, FTIR, XRD, XPS, and BET techniques, followed by testing the properties of the coated papers. The results showed that the HNTs/MSN nanohybrid materials were formed by deposited MSN on HNTs with the Stöber method and in situ growth method. Among the three types of papers, CMC/HNTs/MSN paper exhibited the best comprehensive performance with fast-drying performance and fine transfer effect. Therefore, CMC/HNTs/MSN can be used as a novel type of thermal transfer paper coating with fast ink drying speed and fine transfer effect.
