《Facile Fabrication of Conductive Paper-based Materials from Tunicate Cellulose Nanocrystals and Polydopamine-decorated Graphene Oxide》
Benefiting from the multiple hydrogen bonds formed between PDA-GO and OTCNC and among OTCNCs,the cast conductive paper showed good mechanical strength.However,as a result of the rigidity of OTCNC,the extensibility of the paper was low.Table 1shows that with an increase in the content of PDA-GO,the Young’s modulus of the film first increased from3.48 GPa to 6.78 GPa,and then decreased to 4.70 GPa.This was mainly because with an increase in the PDA-GO content,the catechol group on the PDA-GO surface interacted strongly with the carboxyl and hydroxyl groups on the OTCNC surface to form hydrogen bonds.This hybrid network made the paper more flexible and rigid;however,a further increase in the PDA-GO content led to self-assembling of PDA on the PDA-GO surface,causing the PDA-GO to aggregate.Aggregation led to an uneven dispersion of PDA-GO in the OTCNC matrix.Meanwhile,the continuous network of PDA-GO partially broke the OTCNC network and decreased the rigidity of the paper.It is worth noting that the interaction between OTCNC and PDA-GO was not specific.The OTCNC network could slide on the PDA-GO surface under an external force applied to the paper,thus decreasing the rigidity and extensibility of the paper.
