Uv Shielding 紫外线屏蔽 - Materials with multifunctional surface, such as UV shielding, self-cleaning or antimicrobial properties have been highly desirable. [1] These green technologies have brought the world with innovative dimensions of success with their major use in textiles, unique materials, and biomass in textiles such as highly tensile, distinctive superficial structure, dye capability, self-cleansing stuff, fire-resistant materials, UV shielding, antimicrobial, crease confrontation, stain proof, water-repulsive nature, permanency, etc. [2] Benefitting from a suitable band gap, ceria is an excellent material for UV shielding. [3] Recently, the development of polydopamine (PDA) has demonstrated numerous excellent performances in free radical scavenging, UV shielding, photothermal conversion, and biocompatibility. [4] In addition, this hydrogel film has a series of excellent properties such as UV shielding, antiswelling ability, and good biocompatibility. [5] , UV shielding or antioxidative properties. [6] These properties include chemical reactivity, UV shielding, antibacterial, bio-degradability, anti-oxidation, etc. [7] The enhanced characteristics contributed to the UV shielding and water absorption properties implies the potential of the gw-CNCs to be used as potential nanofiller for packaging application. [8] Further, PANI/poly(C-ddm) coated cotton fabric was studied for its UV shielding and surface properties. [9] This material has potential in applications where biodegradability, UV shielding, and antioxidant properties of hydrogels or thin films are needed, for example in medical, pharmaceutical, food, and feed applications, but also as a functional barrier coating in packaging materials as the hydrogel properties are transferred to the casted and dried films. [10] In summary, the CsxWO3-coated fabrics can achieve multi-functions of UV shielding, heat insulation and self-cleaning by means of a single functional nanomaterial and promise of huge applications in functional textiles. [11] The morphology, structural characteristics, photodegradation ability for organic pollutants, UV shielding, and self-cleaning of the treated fabric were studied. [12] Pathways towards complex molecules and the impact of aerosols (UV shielding, atomic and molecular hydrogen budget, nitriles heterogeneous chemistry and condensation) are evaluated in the model, along with lifetimes and solar cycle variations. [13] In summary, the immobilization of ZnO onto HNT is a viable approach for increasing the thermal stability and improving the UV shielding of HNT. [14] The treated cotton gauze demonstrated remarkable antimicrobial, antioxidant, UV shielding, and wound healing properties. [15] The produced nanocomposites have different applications in many fields such as: gas sensors, solar cells, diodes, UV shielding, lasers, optoelectronics, medical application, dental filling…etc. [16] Various functions such as full-spectra active long wavelength light-induced photocatalyst, full-time active photocatalyst system, UV shielding, oxygen storage capacity (OSC), and hydrophilicity of oxide ceramics based on the precise design of components, particle size, and morphology are introduced also. [17] The UV protective behaviors of prepared polymer composite thin films, make them as promising candidates for UV shielding and sunscreen applications. [18] Then the mechanical strength, especially the retention of wet strength (RWS), optical property, UV shielding, wettability and thermal stability of CNF and ANF nanopapers were further investigated. [19] The results revealed that a considerable improvement in both weathering (42% reduction in ΔE) and corrosion resistance was achieved which was mainly attributed to the considerable enhancement in UV shielding, radical scavenging as well as better dispersion of graphene oxide modified with polyaniline.

[1] In addition, the composite films also displayed excellent UV shielding property. [2] Meanwhile the PHBV/PC/CNC-Cc-7 nanocomposite showed excellent UV shielding, antioxidant, and antibacterial abilities, due to dynamic competition effect of amorphous PC and rigid CNC-Cc on the PHBV microstructure and interaction. [3] Although many preparation methods have been reported so far, it is still a great challenge for Ultraviolet (UV) protection films that simultaneously have extremely high transparency and excellent UV shielding properties. [4] Moreover, due to the UV-absorbing and the photo-thermal conversion ability of PDA, the modified fabrics exhibited excellent UV shielding and solar-induced self-healing properties.

The all-biobased TW showed good thermal stability up to 315 °C and excellent UV shielding property for UV-B and UV-C. [1] In addition, the composite films also displayed excellent UV shielding property. [2] The UV shielding property of the UVPNCs impregnated modified cellulose was compared and a maximum of two folds higher UPF value was found in bio-templated cellulose substrate (UPF range = 223 to 459) than metal treated cellulose substrates (UPF range = 163 to 175). [3] The semiconducting nature and high refractive index of TiO2 conferred UV shielding properties, allowing it to absorb or reflect UV rays. [4] The addition of AgNP not only affected the color of the film surface but also significantly improved the UV shielding properties of nanocomposite films. [5] The UV shielding properties of them were improved after the supporting and were further enhanced by pre-treatment using cationizing agent for both the substrates. [6] UV shielding property of the pigment prints was systematically investigated. [7] Although many preparation methods have been reported so far, it is still a great challenge for Ultraviolet (UV) protection films that simultaneously have extremely high transparency and excellent UV shielding properties. [8] The films have shown excellent antioxidant, antimicrobial, and UV shielding properties and have exhibited exceptional mechanical strength. [9] To contribute to this, the assessment of the incorporation of bio-oil into biodegradable PVA films was proposed in this work in order to obtain coating films with UV shielding properties. [10] Nanoparticles (NPs) have increasingly been applied in consumer and industrial products because of their magnetic, optical, electronic, sensitive, antibacterial, disinfection, and UV shielding properties. [11] With the introduction of Phenylenediamine (PDA), the increasing visible-light transmittance for thermosetting PUs was observed and outstanding UV shielding properties were confirmed by TiO2 photocatalytic degradation of Rhodamine B.
