Soft matter at LCMCP

History to present
      The historical activity of LCMCP is focused on sol-gel science and technology. However, with the development of hybrid materials, including covalent or non-covalent interactions between inorganic and organic scaffolds, more and more soft systems became a topic of research. From mid/late 90’s, a number of competences on soft molecular systems such as polymers, biopolymers and surfactants integrated the research activity of LCMCP, initially in relationship with inorganic systems, and along the years more and more as inorganic-free, stand-alone, scaffold materials.
The development of soft materials constitute an important well of knowledge at LCMCP, as soft systems are nowadays among the major research axes of at least three Teams, to which one could consider minor side activities of other teams within LCMCP. In this regard, LCMCP has developed a broad instrumental panel, but also a set of scientific competences, able to study and understand soft matter. Both university and CNRS researchers represent today the research activity of LCMCP across a wide range of scientific communities, spanning from biology, biomimetism, polymer science, colloid and interface science, physics.

Topics of research
Research involving soft matter can be found across several teams within LCMCP, although none of them has a full activity in this domain.

SMiLES Team. The team is expert in understanding the complex self-assembly processes of soft matter (hydrogels, polymers, lipids, etc.). The activity in the past years has focused on two themes: 1/ understanding the self-assembly process of microbial amphiphiles and the development of soft materials such as hydrogels, complex coacervates, emulsions. 2/ The study of the relationships between the structure, local dynamics and macroscopic rheological behavior of polymers, may them be neutral or charged.

MatBio Team. The team develops a wide diversity of materials and processes to address very diverse areas of application. Most relate to the use of biopolymers in the biomedical field and concern engineering or development approaches for biomaterials (mainly for connective tissues). The integration of new skills has made it possible to develop other fields of research, particularly through the exploitation of the physics of bio-interfaces. Furthemore, based on its experience in handling dense collagen solutions and their extrusion, the Team has developed the 3D collagen bioprinting.

MHP Team. MHP is formed to bring together members with strong expertise in the synthesis, characterization and shaping processes of materials. Among others, the team gathers up experts, in 1/ nanocomposite polymer materials, with an interest in the development of eco-responsible nanocomposite polymers for the reduction of environmental impacts through the creation of dynamic organic-inorganic hybrid networks; 2/ biology, tissue engineering and biomineralization, with the desire to explore and better understand at the fundamental level the “structure-property” relationship (optical and mechanical) of collagenous materials and couple them with suitable shaping processes, in order to obtain integrated solutions for non-toxic and minimally invasive tissue repair. 3/ Printing functional soft matter across multiple scales, with the focus on controlling the composition and structure at the molecular and nanoscale via chemical synthesis and at the microscale and macroscale via 3D printing, enabling the creation of devices with diverse functionalities, including energy devices, printed electronics, sensors, and soft robots.
