摘要： In accordance with some embodiments of the present invention, a composite material is prepared by blending a bio-derived filler into a polymer, wherein the filler includes a diene-modified cellulosic nanomaterial (e.g., cellulose nanocrystals (CNCs) and/or cellulose nanofibrils (CNFs) functionalized to contain a diene) and a dienophile-modified cellulosic nanomaterial (e.g., CNCs and/or CNFs functionalized to contain a dienophile). The modulus of the composite material is reversibly controllable by adjusting a degree of crosslinking between the diene-modified cellulosic nanomaterial and the dienophile-modified cellulosic nanomaterial. This degree of crosslinking is thermally reversible. On one hand, the degree of crosslinking may be increased via a Diels-Alder (DA) cycloaddition reaction at a first temperature, thereby increasing the modulus of the composite material. On the other hand, the degree of crosslinking may be decreased via a retro-DA reaction at a second temperature higher than the first temperature, thereby decreasing the modulus of the composite material.

摘要： A thermoplastic composition that is water-sensitive (e.g., water-soluble, water-dispersible, etc.) in that it loses its integrity over time in the presence of water that can also be injection molded is provided. The composition contains a cellulose derivative, a synthetic water-soluble polymer, and a plasticizer. The desired water-sensitive and moldable attributes of the composition may be achieved in the present invention by selectively controlling a variety of aspects of the composition, such as the nature of the components employed, the relative amount of each component, the manner in which the composition is formed, and so forth.

摘要： Copper salts of ion exchange materials provide copper ions at levels suitable for use as an anti-infective agent. The copper salts of ion exchange materials may be formed using ether and ester derivatives of cellulose, such as carboxymethyl cellulose (CMC), ethylcellulose (EC), methylcellulose (MC), hydroxypropyl cellulose (HPC), hydroxypropyl methyl cellulose (HPMC), hydroxyethyl methyl cellulose (HEMC), cellulose acetate, and cellulose triacetate. Wound dressings having copper salts of ion exchange materials incorporated therein are also provided, and may be used to reduce the incidence of infection in wounds. The wound dressings may also be used to prevent infections in long-term wounds, such as those formed at wound drain, catheter, and ostomy entry sites. Copper salts of ion exchange materials may be used to kill microorganisms, and may optionally be used with additional anti-infective agents.
