Bionic smart recycled paper endowed with amphiphobic, photochromic, and UV rewritable properties

Abstract

The single-use of large shear volume paper has become a serious issue that deteriorating our resources and environment. It is of great significance and challenging to adopt simple, reasonable and...

Achieving sandwich-like laminated composite materials for robust superhydrophobicity, rapid photochromism and photo-mask writable media

“…When heated at 120 1C for 4-10 min, the original color will be restored. Compared with previous work, 25 the color-switching rate of PDMS@TKT has been significantly improved. In short, these results show that the original idea is feasible, and the specific mechanism will be explained later.…”

“…The preparation of TT was carried out according to previous work, 25 and the procedure is given as follows. First calcium chloride solution (0.50 mol L À1 , 60 mL) and citric acid solution (0.05 mol L À1 , 20 mL) were mixed uniformly, then deionized water (160 mL) was added and magnetically stirred for 5 min.…”

“…S1b, ESI †). 25,28 KB has two characteristic diffraction peaks at 2y of 24.61 and 43.31, which correspond to the planes of ( 002) and (100) of the amorphous crystal plane of carbon materials (Fig. S1c, ESI †).…”

“…During heating, the electrons are transferred inversely and PDMS@TKT restores its original color. The reversible display/disappearance process of the PDMS@TKT surface pattern is mainly due to the charge transfer between W 5+ and W 6+ , 25,48,49 and the amount and migration rate of electrons are critical to the color switching rate of photochromic materials. 50 As shown in Fig.…”

Design of a Waste Paper‐Derived Chemically ‘Reactive’ and Durable Functional Material with Tailorable Mechanical Property Following an Ambient and Sustainable Chemical Approach

“…Furthermore, some compressible spongy materials with porous network have already been demonstrated for prospective applications as thermal insulators. [38][39][40] In general, the existing approaches for deriving functional superhydrophobic materials from waste paper primarily depends on the high temperature pyrolysis process, [32][33][34][35][39][40][41][42] which is an energy consuming, sophisticated approach that leads to secondary pollution. Hence, a facile, economic design for converting waste paper into a chemically 'reactive' sponges with the scope to tailor both the mechanical property and chemistry would provide an avenue for a) develloping eco-friendly/economic thermal insulators, b) prospective use in efficient remediation of oil spillages and c) controlled droplet manipulation.…”
