Subject: Collaborative Doctoral Programme PhD studentship: '
Strengthening and deacidification of cellulosic objects of the cultural
heritage using polyaminoalkylalkoxysilanes. Application to library
collections'
Research will be carried out at CRCC (Center for Research on
Conservation, National Museum of Natural History, CNRS)
(http://crc.mnhn.fr) and LPPI (Laboratory of Physico-Chemistry of
Polymers and Interfaces, University of Cergy-Pontoise)
(https://www.u-cergy.fr/fr/laboratoires/lppi.html)
Project
Acidity is a major problem for the preservation of paper based
collections. Late 19th and early 20th century paper collections are
sometimes of mediocre quality, especially newsprint paper. Because of
their acidity and brittleness their access is often very restricted.
CRCC and LPPI have developed novel treatments based on the use of
copolymerized aminoalkylalkoxysilanes (AAAS) that allow the simultaneous
deacidification and strengthening of paper. The PhD shall pursue this
work by studying the interactions between the treatment and its
substrate using solid state NMR, SEM-EDX and nano-FTIR spectroscopy. In
order to adapt the treatment formulation to a large variety of materials
often present in library collections, the chemical and time stability of
the document-treatment system will be investigated. Adapted artificial
ageing methods will be developed to that purpose. A large range of
naturally aged previously treated papers is available as well for
evaluation. The formulation of the treatment will be optimized to adapt
to other materials present in library collections in association with
paper such as bindings, adhesives, inks and other graphic media. The use
of antioxidants will be evaluated in relation to the treatment
efficiency (mechanical testing, chemical properties). In order to test
the treatment on real documents with varied and complex composition,
items from the French National Library, our project partner, will be
treated and evaluated.
Requirements
The preferred candidate has recently finished a Master's degree in
chemistry (organic chemistry, polymer chemistry, material science,
analytical chemistry). A strong interest for cultural heritage
preservation issues will be an asset. Language skills (French and
English) are essential. Being highly motivated and the ability to work
in a team will also be important prerequisites. Work will be equally
divided in both laboratories (CRCC, LPPI) and a few trips to the French
National Library will be planned. The candidate will be enrolled in the
Doctoral School of Sciences and Engineering of the University of
Cergy-Pontoise.
