The main objective of the proposal is development of active multi-functional surfaces with high level of self-healing ability on the basis of Layered Double Hydroxide (LDH) structures. The innovative active treatments are planned to be applied on wide range of metallic substrates relevant for transportation industry. The main targeted functionalities of the created surfaces are related primarily to enhanced fault tolerance and active protection against contamination, biofouling and corrosive damage. The active functionalities will be introduced via incorporation of functional molecules within LDH structures grown directly on the metallic surfaces in result of a conversion process (Figure 1).

The activation of the desired functionality on demand will be achieved utilising intrinsic “smart” release properties of LDHs under various external triggers (Figure 2). An additional surface “health monitoring” functionality will be introduced based on the same principles or using LDH structures as sensing nanoreactors.

The project also aims in creation of stimulating and interdisciplinary R&D and training partnership, with actors from the academia and private sector, promoting the exchange of ideas, methods, techniques as well as enabling an accelerated technology transfer from science to industrial scale and of course a continuous collaborations between the stakeholders. The topic demands strongly innovation and interdisciplinary skills, since there is a lot of pressure from the private sector to develop more sustainable solutions for light-weight transportation solutions. The developed treatments must be compliant with environmental regulations, must present reduced thickness/weight, and must promote energy saves, with longer lifetime (Figure 3). Moreover it has to be considered that the related processing and assembly steps have to be economically competitive. Thus, the actual times are very challenging for this field and new skills and trained people are needed.
