Abstract:

Futuristic technologies are currently envisioning production of flexible electronics devices involving circuits that can bend and stretch, affording outstanding adaptability to applications like consumer electronics. Following the prospect of low-cost and low-time consuming fabrication processes, the project goal is to develop new flexible electronics supports based on novel high-performance supramolecular polyimide systems attained via a simple and innovative approach, leading to concomitant thermal stability, high flexibility and resistance, adequate morphological features, good adhesion to metals and inks, resistance to solvents, good photochromic behaviour, improved dielectric and piezoelectric properties. A significant contribution of the project relies on elaboration of single-step patterning procedures, associated in an authentic manner. Fundamental insights are given on the mechanism of hierarchical patterns formation upon careful combination of either manageable laser irradiation/diffuse coplanar surface barrier discharge plasma exposure/directional pre-strain, to induce surface anisotropy and implicitly enhanced piezo-response. Tests are performed to check the products efficiency. Such fundamental studies will advance the knowledge in material science and engineering by using different synthesis routes and fast and facile morphology texturing approaches, enabling their applicability in flexible/stretchable electronic devices and sensors.

Innovative strategies of enhancing energy storage of dielectrics via reinforcement of green polymers with natural fillers for eco-compatible devices Call name: P 1 - SP 1.1 - Proiecte de cercetare pentru stimularea tinerelor echipe independente - TE-2021

Abstract:

Energy storage evolved to connect intermittent renewable power and globally aimed full time net-zero carbon scenario, forcing this sector to adopt technologies aligned with affordable clean energy via alternative storage solutions. The project brings original contributions in enhancing the energy storage capacity of current the dielectric capacitors by rendering to the new proposed materials not only good balance between dielectric, thermal and mechanical properties, but also an eco-compatible character. The novel strategy relies on development of high dielectric constant (k) composites based on green polymers and natural fillers mixed or not with amounts of other high-k fillers. The efficiency of energy storage of such multiphase polymer systems is controlled by natural fillers nature and processing and through the composition. By study of vaguely reported phenomena (e.g. tricritrical point) that afford increase of k parameter and breakdown strength (Eb), the results expand comprehensive data on research level of high energy-storage materials. Project proposes two original routes to enhance Eb and k that involve concepts of wet film rubbing or lyotropic phase shearing, followed by uni/multidirectional stretching. Dielectric/electrode adhesion is improved via a new procedure that intermingle the aspects of micro-abrasion and plasma discharge. Such eco-compatible dielectrics for storage devices might advance the electrical products towards miniaturization, and integration.

Abstract:

Photovoltaic (PV) technologies have emerged as an alternative to fossil fuels for clean energy production, solving the issue of environmental safety. The efficiency of energy conversion is closely related to the properties of PV components. The project is focused on improving light management in thin film PVs by adapting the refraction at each interface for trapping more photons at the junction. This is essential since sudden variations in the refractive index of each layer covering the active region causes light reflection at the interfaces. The key to this problem lies in synthesis of new transparent PV shielding layers with adaptable refraction features, which is the main concern of the project. Novel thermostable polymer materials are prepared by classic and innovative techniques that lead to transparent coatings with good adhesion to the adjacent conductive oxide. The surface of the shielding layers is subjected to original procedures that generate a combined random-ordered texture for achieving a greater efficiency of the PV by light scattering into the active layer, while diminishing the reflection losses at the entrance facet. The ingenious proposed methods rely on multi-directional rubbing with soft or hard materials or unshearing/shearing liquid crystal embedded in polymer, both procedures followed by laser or plasma exposure. Structural, thermal, morphological and optoelectronic characterizations will be performed to study the performance of synthesized polymer materials and their impact PV efficiency to attain a competitive product. The results of this research plan will bring insightful fundamental knowledge with scientific breakthrough in materials and processing methods for future PVs. If approved, the project will provide the support for young scientists to consolidate this freshly approached research topic of worldwide relevance, giving independence in terms of resources and creative thinking.

Abstract:

The project is focused on obtaining and processing of some transparent polyimide films, with new structures, obtained by novel techniques in order to obtain scaffolds with controlled structure of the morphology for liquid crystal alignment layers and target growth cells. The project brings new contributions in the polyimide surface structure. The novelty is reflected by (1) new polyimide structures synthesize biocompatible nature; (2) investigating issues related unstudied processing techniques that can contribute significantly to improvements in surface structure. This could explain the mechanism of anisotropic structure of the polymer surface with positive impact on CL alignment and performance LCD displays; (3) structure by laser irradiation of photosensitive polymers with strong anisotropy obtain an optimal conformation; (4) analyze the correlation between the mechanical properties of polymers and surface structure generated by AFM nanolithography. Texturing methods will lead to materials with advanced morphological properties as required technologies and applications in tissue engineering.
