Anti-UV Radiation Textiles Designed by Embracing with Nano-MIL (Ti, In)–Metal Organic Framework

Abstract

Protective textiles against harmful solar radiation are quite important materials for outdoor workers to secure their skin from several diseases. Current report focuses on production of anti-ultraviolet radiation (UVR) textiles by incorporation of nano-metal-organic frameworks (n-MOFs). Two different MIL-MOFs, namely, MIL-68(In)-NH and MIL-125(Ti)-NH, were immediately formed inside natural textiles (cotton and silk) matrix in nano size using quite simple and one-pot process. The formation of n-MIL-MOFs inside textiles were confirmed by using electron microscope and X-ray diffraction. Different size and morphology were seen depending on textile type reflecting the textiles' chemical composition role in the nature of prepared MIL-MOFs. For MIL-68(In)-NH, particles with size distribution of 70.6-44.5 nm in cotton and 81.3-52.2 nm in silk were detected, while crystalline disc of MIL-125(Ti)-NH was clearly seen inside textiles. The natural textiles exhibited full UVR blocking after modification, and the UV protection factor (UPF) was linearly proportional with MIL-MOFs and metal contents. Whatever metal type, direct incorporation of MIL-MOF contents greater than or equal to 10.4 g/kg was sufficient to attain excellent UV blocking property. Although 38.5-41.0% of MIL-MOFs was lost during five washings, the washed samples showed very good blocking rate (UPF = 26.7-36.2) supporting good laundering durability.

Ag NPs-Assisted Synthesis of Stable Cu NPs on PET Fabrics for Antibacterial and Electromagnetic Shielding Performance

“…Surface metallization endows textiles with a variety of functions, such as antibacterial, anti-ultraviolet, conductive, and electromagnetic shielding performance [1][2][3][4]. Chemical plating is a commonly adopted approach to metallize textiles, and the process of which includes desizing, roughening, sensitization, activation, and deposition [5][6][7].…”

Porphyrin‐Based Metal−Organic Framework Compounds as Promising Nanomedicines in Photodynamic Therapy

“…[23] The porous nature of the MOFs is the reason why it is invoked as a loading agent for various imaging and therapeutic preparations, [24] and its metal-ligand coordination makes the MOFs have good biodegradability. [25] Porphyrin-MOF nanomedicines have been extensively studied because MOF can effectively avoid the selfaggregation caused by porphyrin and play a crucial part in improving the effect of PDT.…”

Fabrication of Cotton Fabric with Superoleophilic/Superhydrophobic Characteristic on the Modified Surface by Using Fluoroalkylated Oligomeric Silica/Triazine Derivative Nanocomposites

“…Most textile fabrics including cotton are in general likely to absorb significant amounts of water and numerous oils [1][2][3][4][5][6][7]. From this point of view, the modified textile fabrics with surface treated water-and oil-repellent properties have been among the most intensively studied subjects in order to create additional functionalities, such as fire retardancy, antibacterial activity, and UV protection [8][9][10][11]. There has heretofore been a considerable interest in the fabrication of superhydrophobic textile fabrics from the developmental point of view of novel practical applications such as self-cleaning, anti-corrosion, friction reduction, and anti-icing characteristics [2][3][4][5][6][7].…”
