From the perspective of sustainable development and practical applications, there has been a great need for the design of multifunctional transparent cellulose-based composite films. We herein propose a novel concept of improving the mechanical, fire-resistant and ultraviolet (UV)-blue light shielding properties of cellulose-based composite bioplastic films though in situ embedding nano-metal organic framework (MIL-125(Ti)-NH2) into regenerated cellulose gel. Regenerated cellulose hydrogel (CH) with a porous structure acts as a nanoreactor and stabilizer to facilitate the growth and anchorage of MIL-125(Ti)-NH2 nanoparticles (MNPs). Subsequently, hot-pressing induces the formation of transparent MIL-125(Ti)-NH2@cellulose bioplastics (MNP@CBPs). As expected, the MNP@CBPs exhibit exceptional UV-blue light shielding capability, while retaining satisfactory optical transmittance. Meanwhile, with the incorporation of MNPs, the mechanical strength of MNP@CBPs is increased by 6.5∼25.9%. In addition, MNPs enhance the flame retardant effect of the MNP@CBPs. The limited oxygen index (LOI) of the MNP@CBPs increased from 21.95 to 27.01%. The hot-pressing process improves the resistance of the MNP@CBPs to the penetration of water/non-aqueous liquids. This simple strategy would direct sustainable multifunctional MNP@CBPs toward diversified applications: food containers or packaging materials that can reduce or eliminate food spoilage, screen protectors for blocking harmful light, and promising candidates for protective plastic products, among others.

The carbon fibers / rubber composite films were fabricated by compression molding method with butyl rubber (IIR) as matrix and carbon fiber as reinforced material. The mechanical properties and electromagnetic shielding effect of the thin films at different conditions were measured by the WDW electronic universal testing machine according the national standard GB13022-91 and the far-field EMC shielding effectiveness test fixture (DN1015 type) respectively. The results show that the good mechanical properties of composite films with mess ratio of IIR and carbon black of 1:6 and vulcanizing time of 1.5h were obtained at the same other condition that the tensile strength reached 534.65MPa, the elongation rate reached 87.26% and the yield point stress up to124.85MPa. Meanwhile, it is also found that the electromagnetic shielding effect of the thin films shows negative growth at low frequency area ranging from 1MHz to 300MHz. Whereas, the shielding effect increases with frequency at 300MHz ~ 1.5GHz, and the SE value is up to -25dB ~-35dB.
