Laboratory 7. Electroactive Polymers and Plasmochemistry
Head of laboratory: Dr.Mircea GRIGORAȘ
Description Research Groups Publications Projects Infrastructure
Project: Mimicking living matter mechanisms by five-dimensional chemistry approaches

Project: PN-III-P4-ID PCCF-2016-0050
Acronym: 5D-nanoP
Responsible partner (P2): Dr. Ioan Cianga
Duration: 2018-2022
Buget: 945,000 lei

The 5D-nanoP project aims to interface the fundamental scientific field of constitutional dynamic chemistry with the practical approaches of medical chemistry and biomedical applications. In the spirit of the metaphor launched by Jean-Marie Lehn (Nobel Prize for Chemistry, 1987), the project proposes to materialize the concept of 5D chemistry by designing, synthesizing, characterizing and using molecules with conditioned affinity, for the development of supramolecular nanoplatforms, useful as pharmacological and genetic vectors implicated in physiological or pathological processes at the cellular and tissue level.


Project: Novel conjugated structures for high efficiency all-organic solar cell

Project: PN-II-ID-PCE-2011-3-0274, Contract no. 148/2011

Project manager: Dr. Mircea GRIGORAȘ

Duration: 2012-2016

Conjugated polymers with arylaminic structural units (carbazole, triphenylamine) are highly studied in recent years because there are good hole transporting, have photoconductivity, photorefractivity, fluorescence, redox and nonlinear optical properties, being interesting for applications in xerography, electroluminescence diodes field, solar cells, etc. From this point of view, the use of these polymers for heterojunction solar cells (BHJ-bulk heterojunction configuration), where an arylaminic polymer is intimately mixed with an acceptor and deposited sandwiched between a transparent anode ITO, modified with a PEDOT film/PSS and a cathode having low ionization potential (Ca, Al, Zn) is the most economical way to replace silicon-based solar cells.  Within this project, according to the initial proposal, the diversification and optimization of these photoactive organic materials and their use as active layers in photovoltaic devices were addressed. The obtained results were published in 28 scientific papers, participation in 33 national and international scientific events with 14 oral communications and 19 posters.


Project: Polymer materials with smart properties

Project: PN-II-ID-PCE-2011-3-0199, Contract no. 300/05.10.2011

Project manager: Dr. Maria BERCEA

Duration: 2011-2016

By combining new concepts concerning the formation of supramolecular structures under well defined conditions, new polymeric materials with intelligent properties have been developed and characterized. Multicomponent polymer materials obtained by different physical, chemical or combined processes have been reported. Some materials are able to respond to the action of external stimuli in a predictable manner by sharp changes of the physico-chemical properties (viscoelastic or conformational characteristics, hydrophilic-hydrophobic balance, refractive index, permeability, etc.). The obtained results were published in 38 scientific papers, 1 book, one book chapter, and they were presented at 12 national and international scientific events with 11 oral communications and 22 posters.


Project: Organic and hybrid nanostructured conductor materials for multifunctional applications

Project: IDEA PNCDI, ID_993, Contract no. 649/2009

Project manager: Dr. Mircea GRIGORAS

Duration: 2009-2011

The main objective of this project was the synthesis of conductive polymers with improved solubility and processability that allow to carry out in depth studies of molecular and supramolecular structure to establish correlations between structure and properties and to widen the range of possible applications.  The topic of the proposal was mainly focused on two polymeric structures: polyarylenevinylene and polyaniline.


Project: Polymer gels based on clay

Project: PNCDI, ID_980, Contract no. 516/ 22.01.2009

Project manager: Dr. Simona MORARIU

Duration: 2009-2011

The project aimed to develop and characterize hybrid polymer/clay materials with morphologies and structures controlled on a nanometric scale. A series of new gel nanocomposites based on clay and synthetic or natural polymer have been prepared and characterized, following the understanding of some scientific aspects regarding the complex phenomena occuring in these systems. Some materials exhibiting electrostrictive behavior under an electrical impulse were reported. The obtained results were published in 15 scientific papers, 2 book chapters and presented at 19 national and international scientific events.


Project: Textile composites for electromagnetic interference shielding (SIR)

Project: PNCDI II-P4, Contract no. 81050/18.09.2007

PPIMC Project manager: Dr. Ioan CIANGA

Duration: 2007-2010

The overall objective of this project was to obtain and characterize textile composites based on micro metallic wires or conducting polymers, with shielding properties of non-ionizing (radio-frequency) electromagnetic radiation. The novelty brought by this project consisted in combined exploitation of peculiar properties of both micro-ferromagnetic wires and conducting polymers by interfacing them with conventional textile materials.  Complex structures of type metallic yarn-conjugated polymer coated cotton yarn were obtained by „in situ” photochemically induced polymerization technique.

Project: Basics establishment of the directed synergy of integrated micro/nano components in textile composites, aimed for endowing with smart functions the safety equipments designed for aggressive environments (EPINTEL)

National Program of Excellence Research, CEEX, Contract no. 105/19.09.2006

PPIMC Project mananger: Dr. Luminita Cianga

Duration: 2006-2008

Involving two scientific branches, namely the fundamental sciences (chemistry, physics, biology) and the technical sciences (textile engineering, microelectronics, mechanical engineering), the project aimed to create and develop a Romanian network of excellence for fundamental and applied research focusing on the design and production of smart individual safety equipment, integrated within a European themathic. The PPMIC team synthesized a series of 3D porous composites, based on conjugated polymers and cotton textile supports, hierarchically structured at both macro and nanoscopic levels. The obtained materials showed flexibility and conformability, remarkable photophysical, electrochemical and antibacterial properties, with application perspective in both portable bioelectronic devices (useful in telemedicine) as well as as biotextiles.
