“…These polymers require hundreds of years to degrade in the natural environment. Hence, the transfer and disposal of electronic devices in the case of traditional petroleum-based polymers had a severe impact on environmental problems. , Therefore, biodegradable plastics have been considered one of the possible alternatives to reduce the pollution caused by e-waste since they are degraded by the use of microorganisms and decomposed into carbon dioxide and water . Poly(lactic acid) (PLA), a compostable polymer, can be produced by the fermentation of agricultural plants such as corn, potato, sugarcane, and cassava.…”

In this work, poly(lactic acid) (PLA) and nano-silver-coated porous clay heterostructure (PCH) hybrid films were successfully fabricated by a twin-screw extruder. Because of the low dielectric constant of PLA, nano-silver and PCH were employed to enhance the dielectric properties of PLA, and nano-silver-coated porous clay heterostructures (Ag/PCH) with different concentrations of Ag were synthesized by the green process using ascorbic acid as a reducing agent. The results revealed that 1 wt % of Ag-coated PCH (Ag/PCH1) exhibited the highest dielectric constant of up to 40. The physical, chemical, thermal, mechanical, and dielectric properties of pristine PLA and hybrid films were studied. The results indicated that adding Ag/PCH fillers could enhance the dielectric properties of hybrid films, increasing the dielectric constant almost 10 times higher than that of PLA. In addition, Ag/PCH could reinforce the mechanical properties of PLA. Furthermore, we prepared biaxially oriented poly(lactic acid) (BOPLA) films with 4 μm of thickness. The dissipation factor of BOPLA-Ag/PCH was improved, while the dielectric constant was only slightly decreased. However, the BOPLA-Ag/PCH showed better dielectric properties than those of traditional BOPP films. As a result, PLA-Ag/PCH and BOPLA-Ag/PCH hybrid films derived from poly(lactic acid) as biodegradable polymers with superior properties can be applied as dielectric films in capacitors.

“…It might seem that more than two decades of intensive research on noble metal nanoparticles (NPs), mainly gold (Au NPs), have answered almost all the questions about their chemistry and physicochemical properties. [1][2][3] Many of these findings resulted in applications of Au NPs in electronics, [4][5][6][7] optics, [8][9][10] drug delivery, [11][12][13][14] analytical devices, [15][16][17] etc. Behind these achievements, there is a deep understanding of the physicochemical phenomena characteristic of Au NPs and the wide availability of synthetic tools.…”

Ultrasmall gold nanoparticles (NPs) have revolutionized nanotechnology as they are an excellent starting substrate for the synthesis of organic‐inorganic hybrid materials with photonic or energy conversion applications, often with a responsive nature. However, ultrasmall NPs do not sustain plasmonic resonances, preventing their use in plasmon‐related applications. In the presented work, we show a method of chemical modification of ultrasmall gold nanoparticles in order to fabricate dynamically controlled plasmonic thin films. For this purpose, we used the Anti‐Galvanic Reduction process (AGR) to modify the surface of small gold nanoparticles, inducing plasmonic properties without notable size increases. Au@Ag NPs are then modified with liquid crystal‐like organic ligands. The obtained NPs can assemble into densely packed films with long‐range order and temperature‐dependent structural properties. Namely, we detect two, fully reversible phase transitions between the hexagonal and cubic symmetries. The combination of AGR and organic surface modifications enabled us to demonstrate the possibility of managing plasmonic properties in the thin film of ~2 nm diameter metallic NPs.

“…The discussion of radiation effects on polymer composites as the precursors of hybrids, the innovative materials, has opened a large door for the extended applications in several areas of the following activities: modeling [1,2], medicine [3,4], transport [5,6], energy [7,8], electronic devices [9,10], sensors [11,12], food packaging [13,14], building composite materials [15], water desalinization [16] and many others. The inclusion of hybrids through the composite category depends undoubtedly on the deep interpenetration and the specific association of the constituent phases [17]; an explanatory example for the capacity of ionizing radiation for the adjustment of polymer blends into hybrid structuration is the irradiation of chitosan/poly(vinyl alcohol) systems [18].…”

In this paper several aspects of profound modifications caused by high energy exposures are presented as possible candidates for the efficient adjusting processing of polymer materials. The class of hybrid composites receives special attention due to the large spectrum of formulations, where the interphase interaction decisively influences the material properties. They represent potential start points for the intimate uniformity of hybrid morphologies. Their radiation processing turns composites onto hybrid morphology with expected features, because the transferred energy is spent for the modification of components and for their compatibility. The essential changes achieved in radiation processed composites explain the new material behavior and durability based on the peculiar restructuring of polymer molecules that occurred in the polymer phase. During high energy irradiation, the interaction between intermediates born in the constitutive phases may convert the primary composites into hybrids, integrating them into large applicability spheres. During the radiation exposure, the resulting hybrids gain a continuous dispersion by means of new chemical bonds. This type of compounds achieves some specific structural modifications in the polymer phase, becoming stable hybrid composites. The functional properties of hybrids definitely influence the material behavior due to the molecular changes based on the structural reasons. The radiolysis of the vulnerable component becomes an appropriate opportunity for the creation of new material with improved stability. The radiation treatment is a proper conversion procedure by which common mixtures may become continuously reorganized. This review presents several examples for the radiation modifications induced by radiation exposure that allow the compatibilization and binding of components as well as the creation of new structures with improved properties. This approach provides the reference patterns for the extension of radiation processing over the well-conducted adjustments of polymer composites, when certain material features are compulsorily required. From this review, several solutions for the adjustment of regular polymer composites into hybrid systems may become conceivable by the extended radiation processing.
