Hydrothermal method was used to convert graphene oxide in water. Polyvinylpyrrolidone added improve dispersion of and form a stable solution with high concentration. This mix waterborne polyurethane (WPU) prepare WPU/graphene composites. The electrical conductivity WPU greatly improved incorporation graphene, when the filling amount is 4.0 wt%, composite reaches 8.30 × 10 −4 S cm −1 , which little higher than that prepared by situ method.
Abstract In order to compare the effect of monophenyl ring terephthalic acid (TPA) and biphenyl rings 4,4′‐oxybisbenzoic (OBBA) with ether bond on poly(butylene adipate) (PBA)‐based copolyesters properties, two copolyester series adipate‐ co ‐butylene terephthalate)s (PBATs) oxybisbenzoate)s (PBAOs) were synthesized, comparatively investigated. All synthesized had satisfactory number‐average molecular weights in range 26,500–73,000 g/mol. For PBATs copolyesters, crystalline structure...
Abstract Long‐chain branched polylactides (PLA‐LCB) with high melt strength were prepared through a melting reaction using Trigonox301 or dicumyl peroxide (DCP). During this reaction, random chain scissions, branching reactions, and cross‐linking reactions took place, as confirmed by the torque‐time rheograms gel permeation chromatography profiles. It is evident that scissions are more prominent in PLA‐LCB D compared to T . The rheological characterization further elucidated formation of LCB...
