Special Issue Information

Dear Colleagues,

High-energy exposure has profound consequences for the structural configuration of polymer hybrids. Starting from the fragmentation of macromolecules guided by bond energies, the interaction between various classes of filler and host polymers brings about several changes in material behavior. For their extended applications, the stability of hybrids as well as changes in the thermal and mechanical properties of this class of compounds have to be emphasized. Improvement in durability is key for items to be able to operate in the long term. For analysis of the mechanistic approach of polymer/filler interaction, starting from the pristine materials—which are the reference points—is encouraged. Consequently, foreseen applications have to be identified by means of the types and magnitudes of changes whose relevance is connected to radiation processing, ecological technologies involved in the production of new materials especially those with higher energetic resistance,  recycling of polymer wastes, medical purposes of healthcare, development of education and academic knowledge, and the initiation of various studies, where radiation energy is used for attaining the improvement of hybrid behavior for opening of new ways for product characterization of durability, the identification of inner cooperation between hybrid components, and the interconnection of various ranges of expertise. High-energy exposure achieved with electron beams or gamma rays is a versatile procedure for material qualification by accelerated degradation and a pertinent route for the internal inspections to determine the contribution of hybrid components to the material sciences. The manuscripts in this issue are envisaged to become starting points for other investigations simultaneously propelled by the competing approaches of “classical” material assessments.

The formation of polyene-polyyne-based nanocomposites by dehydrohalogenation of the drop-cast-deposited polyvinylidene fluoride, assessment and ion-induced tailoring of their gas sensing properties are reported. The investigated structure was analyzed by scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy, transmission electron microscopy and Fourier-transform infrared spectroscopy, revealing the thickness-dependent incomplete dehydrofluorination of the structure and its porosity induced by KOH treatment. The polyene-polyyne structures modified by low-energy Ar+ were studied by SEM and Raman spectroscopy, which showed the morphology variation, the shortening of chains and the graphitization of samples. The resistive gas sensing properties of the samples were analyzed at room temperature, revealing selective sensing of ammonia vapor by non-irradiated sample and the enhancement of the sensing properties for ethanol and water vapor after ion irradiation. With the ion dose enlargement, the change in the sensing response from electrical conductivity increase to decrease was observed for ammonia and ethanol, allowing us to discuss the origin and tunability of the sensing mechanism of the samples.

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. Full article
