Viscoelastic behaviour of cellulose acetate/triacetin blends by rheology in the melt state

Autor: Alexandra Argoud, Xavier Dreux, Jean-Charles Majesté, Christian Carrot, Caroll Vergelati

Publikováno v: Carbohydrate Polymers
Carbohydrate Polymers, Elsevier, 2019, 222, pp.114973. ⟨10.1016/j.carbpol.2019.114973⟩

The viscoelastic behaviour of cellulose acetate with a degree of substitution (DS) of 245 plasticized by triacetin was studied at short times by dynamic oscillatory measurements. Two distinct regimes and unexpected scaling behaviour according to plas

Macromolecules, American Chemical Society, 2019, 52 (17), pp.6613-6632. ⟨10.1021/acs.macromol.9b00858⟩

We consider the microscopic mechanisms of damaging in plasticized cellulose acetate under tensile stress. We show how they appear and develop during the course of deformation until failure. By usin...

Carbohydrate Polymers, Elsevier, 2019, 204, pp.182-189. ⟨10.1016/j.carbpol.2018.10.013⟩

The mechanical properties of injection molded plasticized cellulose acetate polymers processed with two different plasticizers (Triacetine and Diethyl phthalate) and various weight fractions comprised between 15 and 30 wt % have been investigated. Pl

Conformational analysis of cellulose acetate in the dense amorphous state

Autor: Caroll Vergelati, Anthony Bocahut, Jean-Yves Delannoy, Karim Mazeau

Publikováno v: Cellulose. 21:3897-3912

Atomistic simulations of cellulose acetates (CAs) differing in their degree of substitution have been performed and analyzed in terms of conformation and interaction schemes. The stabilization of the structure of these cellulose derivatives is unders

Atomistic Simulation of the Water Influence on the Local Structure of Polyamide 6,6

Autor: Caroll Vergelati, Sylvain Goudeau, Florian Müller-Plathe, Magali Charlot

Publikováno v: Macromolecules. 37:8072-8081

To understand, at a molecular scale, the effect of water on the structure of the amorphous region of polyamide 6,6 (PA6,6), atomistic molecular dynamics simulations have been carried out. Our results concerning the very local water organization relat

Atomistic Modeling of the Adsorption of Benzophenone onto Cellulosic Surfaces

Autor: Karim Mazeau, Caroll Vergelati

Publikováno v: Langmuir. 18:1919-1927

The interaction between cellulosic material and benzophenone was studied by molecular modeling. A model of the crystalline part of a native microfibril was built from previously published coordinates of the Iβ allomorph. This model presents three fa
