Project Overview
 
 

MUST - MULTI-LEVEL PROTECTION OF MATERIALS FOR VEHICLES BY “SMART” NANOCONTAINERS


FP7 Project and Grant agreement no.: NMP3-LA-2008-214261

 

The project MUST aims at providing new technologies based on active multi-level protective systems for future vehicle materials. "Smart" release nanocontainers will be developed and incorporated in commercial paints, lacquers and adhesive systems to prepare new products exhibiting self-healing properties.

A multi-level self-healing approach combines - in a same system - several damage prevention and reparation mechanisms, which will be activated in response to environmental conditions.

The main objective of MUST is to design, develop, test and apply coated materials and adhesives used as novel multi-level protection systems for future vehicles. The new active protection systems will be based on different types of "smart" nanocontainers incorporated in polymer matrixes and adapted to the level of protection. These systems will result in a radical improvement of the long-term performance of metallic or polymer substrates.

Introduction to MUST
 
 

Why the Concern?

The huge economic impact of environment aggressiveness and corrosion of metallic structures is a very important issue for Europe, which has lost more than €200 billion every year due to corrosion degradation of investments. Transportation is one of the most important industries for corrosion resistance. To meet this demand, application of organic coatings is a cost effective method of improving the corrosion protection and, therefore, the durability of metallic structures.Since 2008, the EU project ”MUST,” established with high European concerns to advance the protection against corrosion and similar defects, has been involved in the design, development, upscaling and application of novel multi-level protection systems like coatings and adhesives. The strategy is to respond to destructive conditions with self-healing reactions. This ability is expected to be most effective if it is reacting at certain stages of degradation with different healing processes. A significant improvement of the durability of protective coatings is evident if early stage degradation phenomena are recovered and, for example, decrease of the barrier properties of the coating is postponed to longer exposure times.
 
   
 
 
The Goal of MUST
 
 

Advanced material protection

“MUST” is an extended multi-level protection approach combined within one system. The protective system reacts adequately to external impacts, and also responds to changes in their internal structure. Different damage prevention and reparation mechanisms are combined within the same system, which are used depending on the nature and the degree of impact from external environment. The multi-level self-healing concept is based on 4 levels of gradual active feedback to the environmental conditions:

  • Incorporation of nanotraps and nanocontainers to absorb aggressive/corrosive species
  • Use of water displacing compounds to be released from nanocontainers as soon as the first micro-defect appear in the coating polymer matrix.
  • Release of polymerizing precursors entrapped in nanocapsules in order to form a new thin polymer film covering the damaged area and repair the layer by preventing crack propagation.
  • Encapsulation of organic and inorganic corrosion inhibitors acting on demand, suppressing corrosion and delaminating processes occurring in open defects.
 
   
 
 
MUST & Future
 
 
Who is the end-user?

The main target groups for the proposed solution are automotive, aerospace and maritime industries. A high industrial interest is demonstrated by the participation of main European industrial end-users and suppliers of coatings and adhesives for vehicles. “MUST” will considerably increase the life cycle of materials and therefore boost the competitive strength of the European transport industry.

The Multi-level protection approach will also open new opportunities for the application of modern light materials (magnesium and aluminum alloys) in transport industries.
