Herein, we report a straigthforward procedure to prepare an excellent intertwined nanosponge solid-state polymer electrolyte (INSPE) for highly bendable, rollable, and foldable lithium-ion batteries (LIBs). The mechanically reliable and electrochemically superior INSPE is conjugated with intertwined nanosponge (IN) poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-co-HFP) and ion-conducting polymer electrolyte (PE) containing poly(ethylene glycol) diacrylate (PEGDA), succinonitrile (SCN) plasticizer, and lithium bis(trifluoromethanesilfonyl)imide (LiTFSI). The conjugated INSPE has both high strength with great flexibility (tensile strength of 2.1 MPa, elongation of 36.7%), and excellent ionic conductivity (1.04 × 10 −3 S•cm −1 , similar to the values of liquid electrolytes). As a result of such special combination, the as-prepared INSPE retains almost 100% of its ionic conductivity when subjected to many types of severe mechanical deformations. Therefore, the INSPE is successfully applied to bendable, rollable, and foldable LIBs that show excellent energy storage performance despite the intense mechanical deformations.

The oil sorption capacity of nettle fibrous assembly and needle-punched nonwoven structures of 100% nettle and nettle/kapok blends 50/50 and 75/25 were investigated. The porosity of nettle fibrous assembly was varied from 91 to 99% and a maximum oil sorption capacity was 56 g/g and 23.90 g/g for high-density oil and diesel oil, respectively. Porosity of fibrous assembly significantly influenced the oil sorption capacity. It has been observed that an increase in the proportion of kapok fibers in the nettle/kapok blended nonwoven structure increased the oil sorption capacity and reduced water sorption than that of 100% nettle nonwoven. This is because of the inherent hydrophobic property of kapok. However, 100% kapok could not be made into needle-punched nonwoven and hence it has been blended with nettle; 50/50 nettle/kapok blended structure showed maximum oil sorption capacity of 28.5 g/g and 22.5 g/g for high-density oil and diesel oil, respectively, which is higher oil sorption capacity than the commercial polypropylene-based nonwoven. The presence of kapok improved the sorption capacity by 13 to 18% when compared to 100% nettle nonwoven.

Polymer Chemistry Applications of Cyrene and its Derivative Cygnet 0.0 as Safer Replacements for Polar Aprotic Solvents

This study explores a binary solvent system composed of biobased Cyrene and its derivative Cygnet 0.0 for application in membrane technology and in biocatalytic synthesis of polyesters. Cygnet‐Cyrene blends could represent viable replacements for toxic polar aprotic solvents. The use of a 50 wt % Cygnet‐Cyrene mixture makes a practical difference in the production of flat sheet membranes by nonsolvent‐induced phase separation. New polymeric membranes from cellulose acetate, polysulfone, and polyimide are manufactured by using Cyrene, Cygnet 0.0, and their blend. The resultant membranes have different morphology when the solvent/mixture and temperature of the casting solution change. Moreover, Cyrene, Cygnet 0.0, and Cygnet‐Cyrene are also explored for substituting diphenyl ether for the biocatalytic synthesis of polyesters. The results indicate that Cygnet 0.0 is a very promising candidate for the enzymatic synthesis of high molecular weight polyesters.
