“…Among the numerous type of transparent polyesters, poly(methylmethacrylate) (PMMA) has been used to replace glassed in various applications, such as aeronautical equipment, automobile, and optical implements based on the high transparency, low birefringence and outstanding hardness . This study aims to achieve an AgNW‐based transparent conductive layer with good adhesion, transparency, flexibility, and electromagnetic shielding with a controllable wet coating deposition process on PMMA substrate.…”

In this work, an acrylate-based organic coating is developed to cover the electrically conductive silver nanowires (AgNWs) to improve the adhesion properties of AgNWs on PMMA substrates. A simple spray coating technique is performed to obtain large scale and highly uniform conductive silver nanowire films on PMMA substrates. The AgNWs covered by organic coatings are evaluated ex situ in terms of adhesion, transparency, electrical, mechanical, and electromagnetic shielding properties. Results indicated the adhesion of AgNWs covered by coatings is greatly superior to the uncovered AgNWs, which can be attributed to the strong hydrogen interfacial bond between the coating and PMMA substrate. Furthermore, the overall properties, including good transparency (!80% in the visible range), flexibility (bending more than 1000 cycles), electromagnetic shielding (larger than 30 GHz from 1 to 18 GHz), meet the requirements of transparent parts in the aeronautical industry, and other commercial fields.

“…While the FTIR spectra of TSS4 and TSS4T1 exhibit many similarities, two additional absorption peaks appear for TSS4T1, representing the Si−CH 3 stretching and bending vibrations at 845 and 760 cm −1 . 44,45 The band intensity of the free hydroxyl band and the hydrogen-bonded hydroxyl groups are significantly decreased for the TSS4T1 sample compared with the TSS4 sample. The spectra shown in Figure 4 demonstrate the successful silylation of the surface of the silica particles Water Vapor Sorption Study on TSS4 and TSS4T1.…”

“…7 Protective layers could be: (1) superhydrophobic coatings to guarantee low water adhesion, so that pollutants and microorganisms are washed away and (2) photocatalytic coatings that favor the light induced degradation of organic deposit on the surface and therefore they can generate self-cleaning properties. [8][9][10] During the last decade, nanoparticles were proposed to target the required performance of such coatings. [11][12][13][14][15][16] Silica-based resins are commercially available and they have been deeply investigated as the stone/resin interactions are crucial to define the surface properties and the efficacy of the coating layer.…”

Halloysite nanotubes-based nanocomposites for the hydrophobization of hydraulic mortar

The treatment of stone surfaces for their protection from ageing caused by natural and anthropogenic effects is an open issue in materials development for Cultural Heritage. We thought interesting to verify the suitability of a modified cellulose biofilm filled with halloysite nanotubes as wax compatibilizers to design a protecting layer. A hydraulic mortar was selected as a stone prototype. To improve the physico-chemical properties of the covering layer, wax microparticles have been incorporated to control transport, consolidation and wettability features. In particular, different application protocols have been studied, namely brushing and spraying, to assess whether the proposed procedures can be scaled up. Colorimetric analysis has been carried out to evidence the applicability in terms of color alteration after the treatment. Water adhesion was investigated by measuring the contact angle values as a function of time to obtain information on spreading and adsorption phenomena. These physico-chemical properties have been correlated to the microstructure evidenced by both electron and optical microscopies. Graphic abstract
