Abstract PPMG-based composite electrolytes were fabricated via the solution method using polyvinyl alcohol and polyvinylpyrrolidone blend reinforced with various contents of sulfonated inorganic filler. Sulfuric acid was employed as sulfonating agent to functionalize external surface filler, i.e., graphene oxide. The proton conductivities newly prepared exchange membranes (PEMs) increased by increasing temperature content oxide (SGO), ranging from 0.025 S/cm 0.060 S/cm. induction optimum level SGO is determined be an excellent route enhance ionic conductivity. single-cell performance test conducted sandwiching PEMs between anode (0.2 mg/cm 2 Pt/Ru) a cathode Pt) prepare membrane electrode assemblies, followed hot pressing under pressure approximately 100 kg/cm at 60 °C for 5–10 min. highest power densities achieved PPMG 14.9 35.60 mW/cm 25 70 °C, respectively, ambient 100% relative humidity. Results showed that exhibit good electrochemical performance. results indicated 6 wt% filler can used alternative applications high-performance fuel cell.

Abstract Unmodified cellulose nanofibrils (CNFs), TEMPO (TCNFs) and lignocellulose (LCNFs) were used to reinforce a poly(vinyl alcohol) (PVA) matrix. The aim of the study was compare performance these nanofillers with respect properties PVA-based biocomposites. XRD thermal analyses showed that CNFs most crystalline thermally stable, followed by LCNFs TCNFs. All improved mechanical PVA, TCNFs providing greatest reinforcement. PVA biocomposite 6% TCNF 55% higher modulus elasticity 58% tensile strength than reference film. stable bionanocomposite among PVA-nanocellulose biocomposites 6 % CNF; degradation (Tonset) started at temperature 4 °C reference. A hydrophilic extract silver fir knotwood added PVA/nanocellulose system produce biologically active biocomposites, its effects on evaluated. shifted Tonset temperatures, content having an even greater effect. While slightly decreased biocomposite, addition 4% LCNF-reinforced increased 10% compared PVA-LCNF biocomposite.

Materials from biological origin composed by renewable carbon facilitate the transition linear carbon-intensive economy to a sustainable circular economy. Accordingly, we use solution blow spinning develop fully biobased cellulose acetate films and nanofiber mats reinforced with fungal chitin nanofibrils (ChNFs), an emerging bio-colloid lower footprint compared crustacean-derived nanochitin. This study incorporates ChNFs into processes for first time. ChNF addition reduces film surface roughness, modifies water affinity, tailors diameter of mats. The covalently bonded β-D-glucans act as binder improve interfacial properties consequently load transference enhance mechanical properties. Young's modulus increases 200 ± 18 MPa 359 99 1.5 wt% ChNFs, while elongation at break ~45 %.
