All reagents mentioned were of analytical grade and used without further purification. Chloroauric acid hydrate (HAuCl4·4H2O), palladium chloride (PdCl2), hexamethylenetetramine (HMTA), polyvinyl alcohol (PVA), amino-propyl-trimethoxysilane (APTMS), and NaBH4 were purchased from Aladdin (Shanghai, China). Zinc nitrate hexahydrate (Zn(NO3)2·6H2O) and sodium sulfate (Na2SO4) were obtained from Sinopharm Chemical Reagent Co., Ltd. (Shanghai, China).
The size of GO was measured with atomic force microscopy (AFM, Dimension Icon, Bruker, Germany). The morphologies of the obtained samples were characterized with scanning electron microscopy (SEM, Hitachi S-3400N, Japan), field emission scanning electron microscopy (FESEM, Magellan 400, FEI Company, USA), and high-resolution transmission electron microscopy (HRTEM, Tecnai G2 F20, FEI Company, USA). UV-visible absorption spectra were measured using a UV-Vis-NIR spectrophotometer (CARY 5000 Scan, Varian, USA). The photoluminescence (PL) spectra were recorded on fluorescence spectrophotometers, viz., Hitachi F-4600 and Shimadzu RF-5301 PC with a 325 nm laser as the excitation source at room temperature.

A UV-Vis-NIR spectrophotometer (Cary 5000 Scan, Varian Inc., Palo Alto, CA, USA) was used to test the transmittance of the film with a scan rate of 600 nm/min. The wavelength of the light beam ranged from 200 nm to 800 nm. The ultraviolet protection factor (UPF), used to represent the UV-shielding performance of the films, was obtained with a YG902 UPF spectrophotometer according to the AS/NZS 4399 standard. The UV-shielding properties of the films were normalized to UPF values (UPF value per weight).
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
