“…Various approaches for tuning the dissolution rate of glasses are currently being investigated, such as intrinsic composition optimization involving growth of silver particles, rare-earth introduction, and substitution of elements. − However, around 3/5 of the atoms in most oxide glasses are oxygens and the possibilities for property tuning are thus relatively limited. Many efforts are therefore also focusing on various post-treatment methods, such as cold and hot solution treatment, fire polishing, gaseous-reagent treatment, coating with polymers as grafting-from method, coating with metal, and SO 2 surface treatment . As an alternative route to enhance or tune the corrosion rate, we here investigate hot isostatic compression, which is a method that does not induce a compositional modification of the glass and could also improve other properties, such as elastic moduli and hardness. , The permanent densification of oxide glasses can be achieved by cold compression at pressures above 8–10 GPa, , but most characterization of such densified samples would be prohibited due to their typical small sample volumes.…”

The chemical durability of oxide glasses is an important property for a wide range of applications and can in some cases be tuned through composition optimization. However, these possibilities are relatively limited because around 3/5 of the atoms in most oxide glasses are oxygens. An alternative approach involves post-treatment of the glass. In this work, we focus on the effect of hot compression on dissolution kinetics because it is known to improve, for example, elastic moduli and hardness, whereas its effect on chemical durability is poorly understood. Specifically, we study the bulk glass dissolution rate of phosphate, silicophosphate, borophosphate, borosilicate, and aluminoborosilicate glasses, which have been compressed at 0.5, 1.0, and 2.0 GPa at the glass transition temperature (T). We perform weight loss and supplementary modifier leaching measurements of bulk samples immersed in acid (pH 2) and neutral (pH 7) solutions. Compression generally improves the chemical durability as measured from weight loss, but the effect is highly composition- and pressure-dependent. As such, we show that the dissolution mechanisms depend on the topological changes induced by permanent densification, which in turn are a function of the changes in the number of nonbridging oxygens and the network cross-linking. We also demonstrate a direct relationship between the chemical durability and the number of chemical topological constraints per atom (n) acting within the molecular network.

“…Chen et al fabricated Cu-coated glass fabric using electroless plating method. These fabrics possessed excellent conductivity of the composites as shielding materials with resistivity down to 2.57×10 −3 Ω.cm [43]. During deposition, initially there exists a low adherence between Cu lms and PET substrate, which causes a low mobility and a low surface conductivity, due to active contribution of the grain boundaries in charge carrier scattering [44].…”

Copper (Cu) thin films are deposited on polyethyleneterephthalate (PET) substrate using ion-beam-sputtering technique. The formation of Cu thin films is successful confirmed as investigated by X-ray diffraction (XRD). Surface morphology of Cu/PET is studied by atomic force microscopy (AFM). The AFM results show that Cu film dewets PET surface and the surface roughness increased from 22.6 nm for PET to 45.3 nm after 40min of deposited Cu/PET. The sheet resistance decreases from 5.16x104Ω to 1.3x104Ω and resistivity decreases from 2.3x10-2Ω.cm to 1.77x10-2Ω.cm, as the Cu deposition time increases from 20min to 60min. The Young’s modulus increases from 2.82GPa to 2.96GPa and the adhesion force enhanced from 14.7nN to 29.90nN after 40min of Cu deposition. The DC electrical conductivity at 300V is improved from 1.75x10-8 S.cm-1 to 3.57x10-8 S.cm-1 after 60min of Cu deposition. The results show that ion beam deposition of Cu on flexible PET platform clearly exhibits improvement over pristine PET in the mechanical and electrical properties which renders it useful for electronics applications.

The purpose of effective electromagnetic interference (EMI) shielding is to prevent EMI from smartphone, wireless, and utilization of other electronic devices. The electrical conductivity of materials strongly influences on the EMI shielding properties. In this work, mainly focus to predict the EMI shielding effectiveness on the ultralight weight fibrous materials by artificial neural network (ANN). Prior to the ANN modelling, the ultra-lightweight fibrous materials were electroplated with different concentration of Ni/Cu and then coated with different silanes. This work utilizes the algorithm to provide accurate quantitative values of EMI shielding effectiveness (EM SE). To compare its performance, the experimental and the predicted EM SE values were validated by root-mean-square error (RMSE), mean absolute percentage error (MAPE) values and correlation coefficient ‘r’. The proposed ANN results accurately predict the experimental data with correlation coefficients of 0.991 and 0.997. Further due to its simplicity, reliability as well as its efficient computational capability the proposed ANN model permits relatively fast, cost effective and objective estimates to be made of serving in this industry.
