chemical modification of cellulose nanofibers and its impact on their hydrophobicity and dispersibility
cellulose nanofibers (cnf) which isolated from wood and non woody plants have attractive advantages comparing with the synthetic fibers, some of the most relevant being the following: low density, renewable sources, biodegradability, availability, and high specific mechanical properties. recently, the use of cnf in green materials, especially as reinforcement in different polymers has been incr...
متن کاملRPMDrate: Bimolecular chemical reaction rates from ring polymer molecular dynamics
We present RPMDrate, a computer program for the calculation of gas phase bimolecular reaction rate coefficients using the ring polymer molecular dynamics (RPMD) method. The RPMD rate coefficient is calculated using the Bennett-Chandler method as a product of a static (centroid density quantum transition state theory (QTST) rate) and a dynamic (ring polymer transmission coefficient) factor. The ...
متن کاملStrategies for Cellulose Fiber Modification
This thesis describes strategies for and examples of cellulose fiber modification. The ability of an engineered biocatalyst, a cellulose-binding module fused to the Candida antarctica lipase B, to catalyze ring-opening polymerization of εcaprolactone in close proximity to cellulose fiber surfaces was explored. The water content in the system was found to regulate the polymer molecular weight, w...
