Research activities

(Co)polymers prepared by ring-opening polymerization

  • Synthesis of polymers based on polyamides, polyesters, polyesteramides (mainly from lactones and lactams
  • Depolymerization to cyclic monomers

Microspheres, (nano)fibres, textiles

  • Preparation of microspheres for adjustable drug delivery application
  • (Nano)fibres prepared by electrospinning, melt-blowing (in cooperation with Technical University Liberec) – synthesis of materials, degradation tests
  • Degradation of cellulose fabrics prepared using ionic liquids (in cooperation with industrial partners)
  • Degradation in both model and real environments – abiotic hydrolysis, Xenon testing chambre, compost, cow manure

(Nano)composites

  • Using different techniques for preparation of (nano)composites - polymerization with in situ intercalation, melt mixing, from dispersion/polymer solution, unconvential methods
  • Exploration of the influence of the additives - graphene(oxide), siloxene, silica, magnetic particles - on properties of the product

3D printing

  • 3D printing of composites, polyamides
  • Post-3D printing improvement of anisotropic mechanical properties
