One of stretchable electronic devices is known as the compliant electrode which can retain good electrical conductivity under deformation. Compliant electrodes from MWCNTs and DPNR were prepared by using a UV-curing process and Triton X-100 as a dispersing agent. The effect of Triton X-100/MWCNTs volume ratio was investigated by transmission electron microscopy indicating the highest dispersion was obtained at the volume ratio of 15.6. The mechanical and electrical properties were investigated by a melt rheometer in a tension mode. The 3%v/v MWCNTs composite possessed an excellent mechanical behavior (Young's modulus 5 1.27 3 10 6 Pa) and a high electrical conductivity (1.03 S/cm) relative to previous works. Under the same experimental conditions, a commercial compliant electrode named Danfoss exhibited the Young's modulus and electrical conducivity values of 7.56 3 10 6 Pa and 2.54 3 10 22 S/cm, respectively, which were inferior to the 3%v/v MWCNTs/DPNR. Moreover, the composite film still retained good electrical behaviors under 100% strain, high extentional strain rate of 1 s 21 , high flexed angle, and repeated stretching cycles (40% strain, 50 times) due to the intimate compatibility between the MWCNTs and the elastomer matrix.

“…For improvement in performance, the inclusion of nanosized fillers as nanoreinforcements is being accomplished. In this context, the world of alkyds has also witnessed greater modifications such as switching to high solids, hyperbranched, waterborne and UV curable alkyds ( Figure 1) [22,23,[25][26][27][28][29]. In our recent review articles, we have described alkyds and their modifications in terms of both in property enhancements and environment-friendly approaches, occurring in the last decade [22,23].…”

Alkyd nanocomposites have attracted great attention in the field of heavy duty coating materials. This is due to the synergistic action of both alkyds (flexibility, biodegradability, compatibility, good gloss retention, durability, weathering resistance) and nanofillers (large surface area to volume ratio). Alkyd nanocomposites show good physicomechanical, physico-chemical, anticorrosive, and antimicrobial performances and thermal stability, with application as anticorrosive, anti-fog, self-cleaning, self-healing, and antimicrobial coatings. In view of present drives and legislations towards environment-friendly coatings, alkyds have undergone modifications as waterborne, high solids, hyperbranched "greener" nanocomposites. The present chapter deals with a brief overview of alkyds, recent advances in environment-friendly alkyd nanocomposite coatings, and the effects of nanofillers on the performance (physico-mechanical, chemical/ corrosion resistance, thermal stability, and others) of "greener" alkyd nanocomposite coatings.

“…For fixing pigments to the surface, the conventional method based on thermal heating is generally used to cure the binder. However, this method is energy and time consuming, and a relatively high curing temperature is needed [2][3][4]. Thermal heating leads to hardening of the coating by evaporation of solvents or water, and crosslinking is provided by a thermal treatment, while UV curing involves hardening of the coating by UV-light-induced polymerisation of the oligomeric binder, and no solvent evaporation or thermal crosslinking is employed [5,6].…”

“…Additionally, the start-up period is faster and the clean-up is less time consuming. It is reported that the UV curing process consumes less electrical energy than the hot air or IR ovens used for drying conventional inks [2,4,8].…”

“…In addition to hardness, the flexibility and elasticity of urethane acrylate cured materials can be adjusted according to various chemical structures. The high crosslink density from the acrylate group that is achieved during curing of UV-curable inks or coatings results in high durability, high abrasion, and chemical resistance [2,4,10]. Because of their low energy consumption and rapid curing features, UV-curable water-borne polyurethane acrylate inks are expected to replace solventbased ones and to become the most favoured industrial coatings [11,12].…”

In this paper, titanium-dioxide-pigmented printing pastes of water-borne, UV-curable polyurethane acrylate binder with two different UV-curing photoinitiator combinations were prepared and screen printed on a black t-shirt fabric. The effects of mercury and gallium radiation sources employed either singly or in combination for UV curing and the total energy level on the printing performance were investigated. The cured textile samples were subjected to colour measurements before and after five cycles of washing, and hiding power and changes in chromacity, hue, and colour were determined. Single-lamp applications of mercury and gallium were not satisfactory, and opaque pigment hindered deep curing, especially at thicker coating levels. It was found that employment of a mercury-gallium lamp system applying an irradiation at medium level can provide pigment printing of opaque white inks with excellent coverage, washing resistance, and medium hardness.
