“…Crystallinity of PLA fiber without CB pigments was 7.67%, which were increased to 12.16 and 31.18% when original CB pigment and PLA‐ g ‐CB (I) pigment were added, respectively, into PLA fiber. The obviously improvement in crystallinity of black PLA fiber containing PLA‐ g ‐CB (I) pigment should be the combination of CB's complementary reinforcement and the excellent compatibility of PLA‐ g ‐CB (I) pigment with PLA matrix . The obviously improvement of crystallinity would be one of the important roles for the improvement of black PLA fiber in breaking strength …”

“…Notably, K/S value of black PLA fiber prepared by PLA ‐g ‐CB pigments was a trace lower than comparative samples containing original CB because of PLA shell around CB pigment . Meanwhile, the color difference ΔE of black PLA fiber prepared by PLA‐ g ‐CB pigments was much better than black PLA fiber containing original CB, revealed the PLA ‐g ‐CB pigments could be deposited on black PLA fiber more uniformly compared to original CB due to the excellent compatibility of PLA‐ g ‐CB pigments with PLA matrix …”

“…However, additional colorant particles will significantly influence fiber properties, which was more serious in PLA fiber due to its semicrystalline property. Most research studies were focused on functionalization particle surface via physical or chemical methods, in order to improve the compatibility of particle in polymer matrices and lower the impact of particle on ordering of polymer molecules . Besides that, the properties such as viscosity, heat, and mechanical properties of composites material depended strongly on the interfacial structure, particle size, dispersibility, and other factors …”

Dope dyeing is a clean method to produce a color polylactic acid (PLA) fiber. In order to investigate the influence factors of dope dyed PLA fiber, three kinds of PLA modified carbon black (PLA‐g‐CB) pigments with different particle size were prepared by open‐ring polymerization method, which were further used for dope dyed black PLA fiber. The resultant black fiber was characterized by TEM, SEM, and DSC. The effect of particle size and concentration of PLA‐g‐CB pigments on color, mechanical property, and crystallization behavior of dope dyed PLA fiber were studied. Dope dyed black PLA fiber reached its good color property including K/S and leveling property when PLA‐g‐CB (I) pigment was the colorant with a concentration of 1.5%. Moreover, the dope dyed black PLA fiber containing PLA‐g‐CB (I) pigment had high breaking strength, crystallinity, fastness, and migration resistance to water and ethanol. © 2019 Wiley Periodicals, Inc.

Bio‐based plastics have received much attraction because they are an alternative to petroleum‐based plastics in recent years. Among them, aliphatic polyesters have garnered the most attention due to their excellent properties. Polyester is primarily synthesized through ring opening polymerization of monomer, and the catalysts used are mostly synthesized through “click” reaction in the laboratory, which exhibits inferior activity and little commercial value. Herein, a facile approach was developed for the synthesis of high molecular‐weight cyclic aliphatic polyesters, specifically poly(valerolactone‐co‐caprolactone) with varying compositions. This involved the ring‐opening copolymerization of ε‐caprolactone (ε‐CL) and δ‐valerolactone (δ‐VL) in the absence of an initiator with commercial hydrogen bond donor triclorocarban and an organic base. The structure and properties of the prepared cyclic polyester were investigated using GPC, 13C NMR, 1H NMR, MALDI‐TOF mass spectrometry, TOF‐SIMS mass spectrometry, differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and X‐ray diffraction (XRD) techniques. The results show that the molecular weight of cyclic polyester can rapidly exceed 40 kDa, with a PDI of approximately 1.10. In comparison to linear polyester, it has a higher melting point and superior thermodynamic properties, thus presenting greater application potential. Finally, based on nuclear magnetic resonance titration, the potential catalytic processes and mechanisms of bimolecular systems on monomers in different environments were discussed. This study not only offers new insights into the structure and properties of cyclic polyesters, but also presents novel bimolecular catalytic systems using commercial urea hydrogen bond donors for the synthesis of cyclic polymer polyesters.

Carbon blacks are important fillers to reinforce, functionalize rubber materials and reduce their prices. However, environment-friendly surface modification of carbon blacks is not trivial to conduct, yet challenging to effectively sever broad rubber galleries. Inspired by wet adhesion of mussel, tea polyphenols (TPs) are coated on carbon blacks by vacuum absorption method (i.e., TP@C) and then they are mixed into nitrile butadiene rubber with ZnCl 2 . Specially, Zn 2+ /TP@C coordination interfaces are formed together with crosslinking structures of Zn 2+ -CN of NBR after hot pressing. As a sequence, the rubber composites achieve superior strength and modulus reinforcement owing to strong interface interactions and good dispersion of TP@Cs. Reversible coordination crosslinking network and TP@C network topology can be rearranged at elevated temperatures, endowing the composite good plasticity and reprocessablity. Furthermore, the composites possess stable shape memory properties for five cycles and good plasticity based shape memory ability, showing great advantages in application potential of smart material fields.
