Short description of company
The Laboratory for Characterisation and Processing of Polymers – LCPP is active within the Institute of
Engineering Materials and Design at the Faculty of Mechanical Engineering, University of Maribor, and is well
known for its research work on interaction of fibre surfaces with different media.
At LCPP different analysis of polymers with the accent on oriented polymers are performed. Research targets are
the structure of natural and chemical polymers, modification of polymer materials and evaluation of the influence
of different processing parameters on structural changes, and consequently, on technological and applied
properties of fibres.
In this way our research work is focused on interactions on fibres surfaces, especially on the determination of the
character of the accessible active interfaces (solid (fibre) /liquids – specific aqueous solutions and process
chemicals) in order to judge the polymers interaction ability, their ion exchange capacity and the progress of
technological processes during the manufacturing of cellulose polymer materials.
Staff qualifications and equipment of the LCPP enables us to:
1) synthesise organic compounds (poly functional, guest-host, fluorescent, pharmacological, …) which are
applicable for fibre surface modification using covalent bonding,
2) perform surface modification of fibres (thermal, chemical, ultrasound, sol-gel surface coating),
3) evaluate fibre surface properties (surface morphology, streaming potential, surface charge, the quality and
quantity of specific dissociable and accessible polymer surface groups, their dissociation constants (pK values) in
solvents of different polarity, contact angle, quality and quantity of fibre surface free energy) and adsorption
character (adsorption kinetics of different adsorbents), and
At LCPP also all conventional analyses of textile materials in any form (fibres, yarns, and 2D textiles such as
woven and knitted fabrics), as well as polymer solutions, melts and solids are performed. These analyses include:
determination of chemical composition, physical-chemical and mechanical properties, quality and damage to
textile and total rheological characterisation.
