Mechano-chemical Preparation of Novel Cellulose-Poly(ethylene glycol) Composite

A new type of cellulose composite was mechano-chemically prepared by ball-milling mixtures of cellulose and poly(ethylene glycol) (PEG). The composites are probably formed by insertion of PEG molecules among cellulose crystalline molecular-chains, and accordingly the compatibilization of cellulose and PEG through the formation of hydrogen-bonds, exhibiting a different mode of orientation of cellulose from that of similar blends from solution systems.
