Functional chitosan (CS) composite films have wide application prospects in many fields. Herein, the lanthanide inorganic-organic hybrid nanospheres with an average diameter of 252 nm (SiO2@TEuTTA) were synthesized by surface modification of silica nanospheres. And the SiO2@TEuTTA was used as luminescent materials and SiO2@TEuTTA/CS composite films were prepared by a simple solution casting method. Subsequently, the compositions and structure, fluorescence and mech. properties of the SiO2@TEuTTA/CS composite films were characterized. The results show that the SiO2@TEuTTA/CS composite films not only have the smooth surface, high fluorescence property, good flexibility and transparency, but also can emit a bright red color under a 365 nm UV lamp. These provide an important basis for the application of the SiO2@TEuTTA/CS composite films on the anti-counterfeiting packing labels. Addnl., the SiO2@TEuTTA/CS solutions have been successfully used as anti-counterfeiting inks due to its transparency and pH sensitive properties. Compared with the traditional luminescent anti-counterfeiting inks, the pH sensitive SiO2@TEuTTA/CS inks can improve the level of information security, which indicates that the SiO2@TEuTTA/CS inks hold great promise for anti-counterfeiting fields. In the experiment, the researchers used many compounds, for example, Trimesoylchloride (cas: 4422-95-1Application In Synthesis of Trimesoylchloride).
Trimesoylchloride (cas: 4422-95-1) belongs to organic chlorides. Organic chlorides can be used in production of: PVC, pesticides, chloromethane, teflon, insulators. Alkyl chlorides are versatile building blocks in organic chemistry. While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available.Application In Synthesis of Trimesoylchloride
