ALL-CELL: From ultra-light to ultra-strong all-cellulose composites via green processing

Finland Distinguished Professor grant awarded to Prof. Tatiana Budtova (Center for Materials Forming of MINES ParisTech, France). The goal of the 4-year project, started in 2016, is to imagine, prepare and characterize new fully biobased materials, all-cellulose composites.

In all-cellulose composites cellulose matrix is reinforced with cellulosic fibers via their partial dissolution. Chemical similarity of the components allow near perfect adhesion between the matrix and reinforcing fibers resulting in strong self-reinforced composite, which are fully bio-based, biocompatible and biodegradable.

  • Various potential applications such as packaging, bio-medical or structural composites and insulation
  • Lightweight all-cellulose aerogels and cryogels will enlarge the family of porous and strong cellulose materials

 

The main focus of the project:
