Electric Properties of Carboxymethyl Cellulose

Carboxymethyl cellulose [C6H7O(OH)3x(OCH2COOH)x]n is a derivative of the regenerated cellulose [C6H10O5]n with hydroxy-acetic acid (hydroxy ethanoic acid) CH2(OH)COOH or sodium monochloroacetate ClCH2COONa. The CMC backbone consist of D-glucose residues linked by -1,4-linkage. The molecular mass of one glucose unit in CMC chain is mCMC = 146.14 + 75.04x, where x  3 is the degree of substitu...

Composite Hydrogels of Bacterial Cellulose - carboxymethyl Cellulose for Drug Release

Bacterial cellulose (BC) is a suitable material for biomedical applications due to its remarkable proprieties, such us: biodegradability, biocompatibility and ready availability. In this paper the swelling and drug release profiles from bacterial cellulosecarboxymethyl cellulose (BC-CMC) composite hydrogels were investigated, in the aim to use such systems in controlled drug delivery field. Ibu...

Fractionation of cornstalk into cellulose and lignin for the production of sodium carboxymethyl cellulose

This thesis project aimed to fractionate cornstalk into cellulose and lignin, and utilize the crude cornstalk-derived cellulose for the production of sodium carboxymethyl cellulose and the lignin for the sybthesis of bio-based phenol-formaldehyde resole resins as wood adhesives. In this thesis work, cornstalk was efficiently fractionated into crude cellulose and crude lignin in mixed solvents o...

Cellulose fibers and nanofibrils for adhesive reinforcement

Introduction In wood industry, adhesive bonding is one of the key process steps. To ensure continuing technological progress in wood industry it is necessary to explore new possibilities of improvement in adhesive bonding. The potential routes for performance improvements suggested by a state of the art report issued by COST Action E13 Wood Adhesion and Glued Products (Dunky et al. 2002) focus ...
