At low temperature the dielectric spectra are dominated by a dipolar process labelled as a β-relaxation, whereas electrode polarization and the contribution of dc-conductivity dominate the spectra at high temperatures and low frequency. The CMC concentration affects the morphological structure of cellulose and subsequently alters its physical properties. X-ray diffractometry measurements show that increasing the concentration of CMC promotes a decrease of the Iα/Iβ ratio. This structural change in BC, that involves a variation in inter- and intramolecular interactions (hydrogen-bonding interactions), affects steeply their molecular dynamics. So, an increase of CMC concentration produces a significantly decrease of the β-relaxation strength and an increase of the dc-conductivity.Fondo Nacional de Desarrollo Científico y Tecnológico - FondecytengElsevier LtdCarbohydrate Polymersinfo:eu-repo/semantics/openAccessX ray diffraction analysisCellulose-1Dielectric relaxation-1Graphene-1Hydrogen bonds-1Spectroscopy-1Temperature-1Thermodynamic stability-1Bacterial cellulose-1Broadband dielectric relaxation spectroscopy-1https://purl.org/pe-repo/ocde/ford#1.04.00-1Monitoring molecular dynamics of bacterial cellulose composites reinforced with graphene oxide by carboxymethyl cellulose additioninfo:eu-repo/semantics/articlereponame:CONCYTEC-Institucionalinstname:Consejo Nacional de Ciencia Tecnología e Innovacióninstacron:CONCYTEC20.500.12390/625oai:repositorio.concytec.gob.pe:20.500.12390/6252024-05-30 15:58:19.552http://purl.org/coar/access_right/c_14cbinfo:eu-repo/semantics/closedAccessmetadata only accesshttps://repositorio.concytec.gob.peRepositorio Institucional CONCYTECrepositorio@concytec.gob.pe#PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE#<Publication xmlns="https://www.openaire.eu/cerif-profile/1.1/" id="5d597129-149a-4af5-8afa-22e63e067933"> <Type xmlns="https://www.openaire.eu/cerif-profile/vocab/COAR_Publication_Types">http://purl.org/coar/resource_type/c_1843</Type> <Language>eng</Language> <Title>Monitoring molecular dynamics of bacterial cellulose composites reinforced with graphene oxide by carboxymethyl cellulose addition</Title> <PublishedIn> <Publication> <Title>Carbohydrate Polymers</Title> </Publication> </PublishedIn> <PublicationDate>2017</PublicationDate> <DOI>https://doi.org/10.1016/j.carbpol.2016.10.001</DOI> <SCP-Number>2-s2.0-84990852265</SCP-Number> <Authors> <Author> <DisplayName>Sanchis M.J.</DisplayName> <Person id="rp01254" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Carsí M.</DisplayName> <Person id="rp01256" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Gómez C.M.</DisplayName> <Person id="rp01255" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Culebras M.</DisplayName> <Person id="rp01253" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Gonzales K.N.</DisplayName> <Person id="rp01260" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Torres F.G.</DisplayName> <Person id="rp00532" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> </Authors> <Editors> </Editors> <Publishers> <Publisher> <DisplayName>Elsevier Ltd</DisplayName> <OrgUnit /> </Publisher> </Publishers> <Keyword>X ray diffraction analysis</Keyword> <Keyword>Cellulose</Keyword> <Keyword>Dielectric relaxation</Keyword> <Keyword>Graphene</Keyword> <Keyword>Hydrogen bonds</Keyword> <Keyword>Spectroscopy</Keyword> <Keyword>Temperature</Keyword> <Keyword>Thermodynamic stability</Keyword> <Keyword>Bacterial cellulose</Keyword> <Keyword>Broadband dielectric relaxation spectroscopy</Keyword> <Abstract>Broadband Dielectric Relaxation Spectroscopy was performed to study the molecular dynamics of dried Bacterial Cellulose/Carboxymethyl Cellulose-Graphene Oxide (BC/CMC-GO) composites as a function of the concentration of CMC in the culture media.
