Fabrication of titania nanowires incorporated paper sheets and study of their optical properties

Abstract

Paper sheets were fabricated by incorporating TiO 2 nanowires (NWs) (diameters ca. 20 to 40 nm and length between 1 to 7 m) as filler by the standard Handsheet making procedure. The TiO 2 NWs were synthesized by hydrothermal method using commercial TiO 2 as precursor. It was observed that the TiO 2 NWs incorporation in the paper sheet improves the optical properties such as brightness from 55.2 to 61.9% ISO and opacity from 93.1 to 97.5% ISO. The TiO 2 NWs as well as the NWs incorporated paper sheets were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, field emission scanning electron microscopy and thermogravimetric analysis.

Incorporation of nano-metal particles with paper matrices

“…To avoid the agglomeration of TiO 2 nanowires in the paper matrix, a tri-block copolymer Pluronic 123 (P123) was used, the hydrophilic end of this copolymer interacted with the TiO 2 nanowires forming a layer on the surface of TiO 2 nanowires. Consequently, incorporation of dispersed TiO 2 nanowires (of diameter ranged from 20 to 40 nm) in paper matrices were obtained as shown in (Figure 10 c) [61,62].…”

Embracing Additive Manufacturing Technology through Fused Filament Fabrication for Antimicrobial with Enhanced Formulated Materials

“…3D Printing, also known as fused filament fabrication (FFF), continues to open new routes to the production of high-performance and complex structures with enhanced properties and dynamic shapes that are unattainable via conventional fabrication methods. Developing new material for different applications of the 3D Printing technology [ 1 ] usually involves many challenges, such as the mechanical properties [ 2 ] as well as the failure mechanism [ 3 , 4 , 5 ]. The FFF technology opened new horizons for a wide range of applications [ 1 , 2 ] but limitations still face this fast-moving sector [ 6 , 7 , 8 ].…”

“…Although the 3D Printing technology contributes to the increasing levels of wasted material of polymeric base [ 9 , 10 ], on the contrary, there are unlimited benefits that are continuously increasing day by day. Owing to its innovation-driven approach, 3D Printing has been expanding to several fields, such as analytical chemistry for chromatography [ 3 ] and fluorescence techniques [ 4 ], optic fibers for increased optical and mechanical performance [ 5 , 6 ], membrane technology for increased adsorption of chemicals [ 7 ], space technology to develop tools on-site [ 8 ], and medicine for the development of implants and medical devices [ 3 , 5 , 7 , 9 , 10 , 11 , 12 , 13 ].…”

Immobilization of titania nanoparticles on the surface of cellulose fibres by a facile single step hydrothermal method and study of their photocatalytic and antibacterial activities

“…[16][17][18] In all these reports the TiO 2 incorporation/immobilization in the paper matrices is a multistep process, where the rst step involves the synthesis of TiO 2 nanoparticles and the incorporation of these synthesized nanoparticles into the paper is executed in the second step. 16,17,23 Uniform distribution, retention and agglomeration of the nanoparticles are big challenges in these processes. 16,23 Here, we report a facile method, where the synthesis and the immobilization of the nanoparticles on the surface of the cellulose bers are carried out in a single step.…”
