NANOMATCH is an EU research project funded through the Seventh Framework Programme. SP1-Cooperation; Collaborative project; Small or medium-scale focused research
project. Subprogramme Area: Development of advanced compatible materials and techniques and their application for the protection, conservation and restoration of cultural heritage
assets. FP7-ENV-NMP.2011.3.2.1-1 – Grant Agreement No. 283182
- EU-FP7 Supported Project: Grant Agreement No 283182
- Duration: November 2011 - October 2014
Alkaline earth and semi-metal alkoxides molecular precursors will be synthesised tuning their properties to the
characteristics of the substrate to be treated and to the
specific demands of their required function. The nanocoating deposition of these precursors in the historic materials will lead to nano-structured conservation products
compatible with the main built heritage materials: stone,
wood (including polychrome materials) and glass.

Government authorities, restoration architects and conservation scientists have been confronted for many years
with the problem of the deterioration of historic building materials, in particular stone, wood and glass. This
issue has become increasingly urgent as climate change
and atmospheric pollution are worsening the effects of
natural weathering, whilst socio-economic realities are
requiring a more sustainable management of the built
heritage. Furthermore, the current use of inappropriate
commercial treatment products, especially polymers that
were designed for purposes completely other than cultural heritage conservation, has had detrimental effects on
historic materials in recent years due to the fast deterioration of these products that impacts the treated materials.
The products will be first assessed in the laboratory and
then evaluated in the field through four different cases
studies in Cologne, Florence, Bucharest. and Oviedo.
Combining the most recent advances in the fields of
nanotechnologies and conservation science, the NANOMATCH project will address these issues by developing
a new class of innovative nano-structured materials,
tailored specifically to historic materials and adapted to
a climate change context. They will provide enhanced
sustainability, compatibility and efficiency compared to
conventional conservation products, thus offering a real
alternative and renewing the market dedicated to the
conservation of the built heritage.
The best processing parameters for industrial production
will be defined and the costs and benefits of the new
products in economic terms will be determined. An
exploitation plan, centred on SME interests, leading to a
business model will be also developed with an evaluation
of the risk during the production/dissemination and
exploitation in the market.

The metal-alkoxides showing the highest performance
and safety among the molecular precursors, also in
comparison to commercial products, will be assessed for
their introduction to the market. In the different steps of
the project, the hazard impact of the metal alkoxides on
environment and human health will be monitored during
the production and after the conservation treatments due
to the possible environmental release of nanoparticles
from the treated substrates by considering the transformation that the composts could undergo.

Overview of the New Materials
NANOMATCH will develop two conservation products: a new alkaline earth alkoxide product for stone and wood
will be created and an already existing aluminium alkoxide product for glass. (EU project Constglass) will be optimised.
Stone and Wood
Within the bilateral French-Italian Project Galileo 2009, preliminary feasibility tests performed on limestone and
wall paintings demonstrated that selected calcium alkoxides react with the atmosphere to produce calcium carbonate,
identified by XRD measurements as calcite and vaterite. Depending on the experimental conditions, the vaterite/
calcite ratio identified in the final calcium carbonate varies considerably, underlining the importance of the solventdispersion agent interactions and the role of the substrate. Moreover, impregnation of a porous substrate, simulating
a deteriorated stone, with a solution of calcium methoxide produces a crystalline nano-structured calcium carbonate
film which is deposited on the surface of the substrate grains with a good adhesion, without cracks or formation
of ungrafted particles. Unlike silica coating created by traditional consolidants like TEOS, this film homogeneously
penetrates all the substrate pores, binding its grains together, thus fulfilling the primary requirements of a consolidant.
Furthermore, non-destructive measurements showed that this coating increases the stone cohesion by 20% while,
thanks to its nano-dimensions, it affects neither its surface appearance nor its water vapour permeability.
Glass
A molecularly dispersed aluminium alkoxide complex (A18) was developed during the EU project Constglass. Its
promising properties as a glass consolidant are due to its very low viscosity that allows it to penetrate into the smallest
capillaries of the corroded glass. After the solvent evaporation, the micro porous residue consists of an aluminium
oxide precursor which subsequently hydrolyses very slowly leading to an oxide network chemically bonded tightly
to the inner walls of the cracks. This newly formed micro porous oxide network provides a guiding structure that is
gradually filled in by glass components migrating from the vicinity of the crack, creating a new glass matrix within the
crack, thus healing the corroded glass.
The NANOMATCH project aims at renewing the conservation product market by developing new, advanced, compatible and sustainable nano-structured consolidants as an alternative to conventional products, thus improving the
preservation of Europe’s valuable built heritage.
