The main objective of this research proposal is to develop and characterize new high performance functional materials based on polymer composites and nanocomposites particularly used for hydrogen fuel cells, piezoelectric sensors and photovoltaic cell devices. We already developed bipolar plate and electrode prototypes for proton exchange membrane fuel cells and we will use new nanomaterials, carbon nanotubes and graphene, in order to investigate their synergetic effect as conductive fillers to decrease bipolar plate thickness and improve its mechanical properties and electrical conductivity. Our expertise in fluorescence technique will be explored to characterize (for the first time) the evolution of the electrical conductivity the nanocomposites during their processing. We will also focus on improving the compatibility between new membranes and electrodes developed in our Lab by synthesizing new compatibilizers from the same monomers used in the synthesis of these membranes. Our research will also focus on the development of new low cost/high-performance photoactive materials based on semiconductive polymers and specific nanomaterials. We recently developed simple routes to synthesize various kinds of semiconductive lead sulfide nanoparticles of controlled structures. These nanoparticles will be used to develop new nanocomposite photovoltaic flexible films of high photon capture and charge transfer toward cell electrodes. Cell prototypes will be developed and characterized for their conversion efficiency. We are presently in an early stage of a new project on the development of flexible piezoelectric cellular films using original processing techniques. We will optimize these processes to develop and stabilize the cellular structure of the films. Also, we will optimize charge storage, which allows giving the piezoelectric character de the developed films. Finally, we will evaluate the impact of film heat treatment on the piezoelectric and mechanical properties of the developed cellular films.

该研究建议的主要目的是开发和表征基于聚合物复合材料和纳米复合材料的新高性能功能材料，这些材料特别用于氢燃料电池，压电传感器和光伏电池设备。 我们已经开发了用于质子交换膜燃料电池的双极板和电极原型，我们将使用新的纳米材料，碳纳米管和石墨烯，以研究其作为导电填充剂的协同作用，以减少双极板厚度并改善其机械性能和电导率。我们将探索我们在荧光技术方面的专业知识，以表征（首次）纳米复合材料在处理过程中的电导率的演变。我们还将专注于改善实验室中新的膜和电极之间通过从合成这些膜中使用的相同单体的新兼容器开发的新膜和电极之间的兼容性。 我们的研究还将集中于基于半导体聚合物和特定纳米材料的新的低成本/高性能光活性材料的发展。我们最近开发了简单的途径，以合成受控结构的各种半导体硫化物纳米颗粒。这些纳米颗粒将用于开发高光子捕获的新纳米复合柔性膜，并向细胞电极转移。细胞原型的转化效率将开发和表征。 目前，我们正处于一个新项目的早期阶段，讲述了使用原始处理技术开发柔性压电细胞膜的发展。我们将优化这些过程以开发和稳定膜的细胞结构。另外，我们将优化电荷存储，这允许给予压电角色DE开发的膜。最后，我们将评估膜热处理对已发达细胞膜的压电和机械性能的影响。
