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

Abstract

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.

Solid state mechano‐chemical grafting copolymerization of hydroxyethyl cellulose with acrylic acid

“…The temperature of the powder mixture was measured with a DM-6902 K-type thermometer (Victor Hi-tech Co., Shenzhen, China). The temperature before milling was approximately 25 C and rose to nearly 34 C after the completion of the process.…”

“…Meanwhile, the mechanochemical effects on cellulosic materials were also studied. Endo 25 prepared a novel blend of cellulose and poly(ethylene glycol) by improving their compatibility through the formation of hydrogen bonds between the two composites. Qiu et al 26 prepared a cellulose-maleated polypropylene composite through the formation of ester bonds between them.…”

Cellulose Nanofibers and Its Applications for Resin Reinforcements

“…With the aim of widening its application possibilities, several works have been documented on mechanochemical treatments of cellulose in the dry state and in the wet states. [1-6] Endo et al [1][2][3][4] developed novel cellulose composites by ball milling mixtures of cellulose and poly(ethylene glycol) (PEG). The composites are reported to have formed by insertion of PEG molecules among the cellulose molecular chains.…”

“…The composites are reported to have formed by insertion of PEG molecules among the cellulose molecular chains. [3,4] Works of Kondo et al [5] and ours [7] appeared as patent publications. In the former case, fine cellulose powder (average powder length and width: 28 and 11 μm, respectively) was pulverized in aqueous suspension by counter collision at a pressure of 200 MPa, being done once or repeatedly up to 60 times or more, using an ultra high-pressure homogenizer, Star Burst System HJP-25005( Sugino Machine Ltd.).…”

“…In fact, our research interests were stimulated by the works of Endo et al, [1][2][3][4] and we started to research suitable methods for efficient wet mechanochemical treatment of biomass. Works were performed with the intention of determining pretreatment methods for successive efficient chemical reactions for cellulose in water.…”
