“…An artificial superhydrophobic coating can be created on a hydrophilic surface by building suitable roughness and lowering surface free energy. Following decades of development, there have been many reports on the preparation of a superhydrophobic coating applied to different materials surfaces, such as wood [ 8 ], clothes [ 9 , 10 ], metal [ 11 , 12 , 13 ], filter paper [ 14 ], glass [ 15 ], and plastic [ 16 ]. Different preparation methods have also been employed, such as sol-gel [ 17 ], immersion [ 18 ], electrochemical deposition [ 19 ], spraying [ 20 , 21 ], etching [ 22 , 23 ], chemical vapor deposition (CVD) [ 24 ], and electrospinning [ 25 ].…”

It is a challenge for a superhydrophobic coating to overcome the poor robustness and the rough surface structure that is usually built using inorganic particles that are difficult to degrade. In this study, a robust superhydrophobic coating is facilely prepared by using commercial biodegradable lignin-coated cellulose nanocrystal (L-CNC) particles after hydrophobic modification to build rough surface structures, and by choosing two different adhesives (double-sided tape and quick-setting epoxy) to support adhesion between the L-CNC particles and the substrates. In addition to excellent self-cleaning and water repellence properties, the resulting coatings show outstanding mechanical strength and durability against sandpaper abrasion, finger-wipe, knife-scratch, water jet, UV radiation, high temperature, and acidic and alkali solutions, possessing a wide application prospect.

“…Only the (104) plane of calcite was found in the XRD pattern. Other characteristic peaks of calcite were missing, which may be due to the low crystallinity of calcite in the composite (Niu et al 2014;Xu et al 2017). Overall, XRD results indicated the successful in-situ precipitation of calcite into the RC film.…”

The application of cellulose hybrid biocomposites filled with calcium carbonate has attracted wide attention in packaging and other fields in recent years. In this study, regenerated cellulose (RC) films filled with calcium carbonate were successfully prepared by dissolution, regeneration, and in situ precipitation of CaCO3. The optical, mechanical, physical, and chemical properties of biocomposites were examined by UV-visible spectroscopy, tensile testing, scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and thermogravimetric analyses (TGA). The results showed that RC films with different CaCO3 contents exhibited good flexibility, optical properties, mechanical strength, and thermal stability. The RC biocomposite filled with calcium carbonate showed a tensile strength of 84.7 ± 1.5 MPa at optimum conditions. These RC biocomposites filled with CaCO3 may find application in packaging.

“…These results imply that the uncoated paper substrate contains calcium carbonate species and the coating of substrates with the resins results in the coverage of the substrate with the resins. The relatively hydrophobic nature of the uncoated paper substrate likely relates the calcium carbonate additives present in the paper (Niu et al 2014). EDX analysis further supports the presence of F and Cl in the FR coated paper and Si in the NFR coated paper substrates.…”

The ability to pattern highly conductive features on paper substrates is critically important for applications in radio frequency identification (RFID) tags, displays, sensors, printed electronics, and diagnostics. Ink-jet printing particle-free reactive silver inks is an additive, material efficient and versatile strategy for fabrication of highly conductive patterns; however, the intrinsic wetting properties of cellulose based papers are not suitable to serve as substrates for this process. This study reports one-step and practical modification of the surface of paper substrates using industrially available materials. The paper substrates were dip-coated with films of hydrocarbon and fluorocarbon based polymeric resins. Ink-jet printing particle-free reactive silver inks on the modified paper substrates followed by fast thermal annealing resulted in highly conductive patterns. The coatings improved the conductivity of the patterns and reduced the number of printing layers required to obtain conductivity. We finally demonstrated fabrication of a printed RFID tag on the coated paper substrates operating at the frequency range of 865-870 MHz.
