“…The TGA curves in Figure b show the change of thermal stability. It can be seen that the thermal decomposition of the pristine paper is a multistage process, − mainly including the loss of physically absorbed water at 100 °C, pyrolysis of hemicellulose and cellulose between 250 and 400 °C, and decomposition of the inorganic filler between 650 and 770 °C. The differential thermogravimetric (DTG) curves in the inset of Figure b show that the peak temperature of the paper’s weight loss is about 372.2 °C.…”

Technology advances in flexible and wearable electronics have promoted the booming development for high-performance flexible electrodes. In this work, we fabricated a highly conducive paper-based electrode by coating silver nanoparticles (AgNPs) on common cellulose paper using a polymer-assisted metal deposition strategy, where the mussel-inspired polydopamine (PDA) layer was applied as an interface to facilitate the bonding between paper substrates and AgNPs. Dense AgNPs can directly grow on the surface of PDA-coated paper at mild conditions, forming a highly conductive layer. The as-fabricated flexible paper electrode displays a high electrical conductivity of 4058.1 S/m and low sheet resistance of 6.5 Ω/sq, which outperforms many reported counterparts. Moreover, with the strong interfacial reinforcement by PDA, the AgNPs adhere to the paper tightly and the electrode presents a notable stability under sonication and mechanical bending. The used paper is low cost and environmentally friendly, and the preparation process is simple and green without the need of extreme conditions or strong solvents, which can be scaled up to large-scale fabrication.

RESUMOO estudo avaliou a eficiência do processo de eletrofloculação (EC) para o tratamento de efluentes de uma indústria de papel reciclado em comparação com o método físicoquímico aplicado atualmente pela empresa. O desempenho da EC foi analisado, variando os materiais dos eletrodos (Al e Fe), ainda foi utilizada outra rota de tratamento com eletrodo de Al com adição de polímero aniônico. A validação dos resultados se deu através da medição dos índices de pH, DQO, cor, turbidez, fósforo, óleos e graxas, FDS, TDS e TSS com posterior realização de Anova e teste Tukey dos resultados obtidos. A remoção máxima de DQO foi obtida na condição T3, com redução de 13,75% em comparação com o tratamento físico-químico, já para a remoção cor foi mais eficiente com Al, a turbidez obteve redução de até 73,68% com Fe, já os índices de fósforo reduziram em 87,77% na condição T1. Os resultados de pH, óleos e graxas, FDS, TDS e TSS foram similares as literaturas e atendem as legislações vigentes. Portanto o processo de eletrofloculação se mostra promissor no tratamento de águas residuais da indústria de papel reciclado, obtendo resultados superiores ao método físico-químico.
