Security printing is of the utmost importance in the information era. However, the excessive use of inks and paper still faces many economic and environmental issues. Thus, developing erasable inkless security printing materials is a remarkable strategy to save resources, protect the environment, and improve information security. To this endeavor, a photoresponsive lanthanide-polyoxometalate-doped gelatin film with high transparency was developed through the solution casting method. Attenuated total reflection Fourier-transform infrared spectroscopy confirmed the electrostatic and hydrogen bond interactions between gelatin and lanthanide-polyoxometalate. Absorption spectra, luminescent spectra, and digital images indicated that the film displayed reversible photochromism behavior and was accompanied by luminescent switching property upon exposure to UV irradiation and oxygen (in the dark) alternately, which allowed its potential application as a reprintable medium for inkless security printing. The printed information can be erased upon exposure to oxygen in the dark, and the film can be reused for printing again. The film exhibited excellent erasability, reprintability, renewability, and low toxicity. In addition, multiple encryption strategies were designed to improve information security. This work offers an attractive alternative strategy for constructing a reprintable film for inkless security printing in terms of simplifying the preparation process, saving resources, and protecting the environment.

“…However, because of the weak coordination between AP and the organic raw material after hydrolysis of phosphate ester, the materials obtained in the literature are basically AP inorganic materials without organic compounds. Yang used citrate as a regulator to prepare AP microspheres containing organic acids [14], and Shu et al used 2, 3-pyridine carboxylic acid as raw material to synthesize functional materials with photochromic function [15], which proved that carboxylic acid could coordinate with inorganic phase in AP. Therefore, Yang and Zhan of our group used natural rosin as raw material to obtain dehydroabietyl phosphate triester (DDPT) and dehydroabietyl phosphate diester (DDPD), which contained organic acid after hydrolysis to synthesized hybrid AP materials by hydrothermal method [16,17].…”

Due to the combination of organic and inorganic advantages, organic@inorganic hybrid materials have important applications in drug-loading, water-treatment and other fields. Rosin@apatite (AP) hybrid materials with various morphologies were designed and obtained by in-situ reaction using two novel rosin-based phosphoester surfactants as organic phosphorus sources. The hybrid materials combined multi-ring, multi-electron groups of natural rosin diterpene and strong physical adsorption properties of apatite. Block and sheet rosin@AP hybrid materials were prepared by sol-gel method with mild reaction conditions. The materials have excellent adsorption capacity of phenol (9.2 mg/g) and loading capacity (492 mg/g) of adriamycin (DOX) induced by π–π stacking interaction with rosin bases. The content of rosin based organic materials in hybrid materials is as high as 47.5% by thermogravimetric analysis. The formation mechanism of hybrid materials was speculated in detail.
