“…Recently, liquefaction of rigid polymers has been demonstrated by introducing different counter‐charged oligomers into rigid polymer matrices, [ 7 ] such as DNA oligonucleotides, [ 8 ] protein, [ 9 ] polyaniline derivatives, [ 10 ] and poly( p ‐phenylene terephthalamide) derivatives. [ 11 ] Such liquefied rigid polymers usually have flexible processing properties due to their low melting points.…”

The phase behavior of biomolecules containing persistent molecular entities is generally limited due to their characteristic size that exceeds the intermolecular force field. Consequently, favorable properties normally associated with the liquid phase of a substance, such as fluidity or processability, are not relevant for the processing of biomolecules, thus hindering the optimal processing of biomolecules. The implied problem that arises is how to convert folded biomolecules to display a richer phase behavior. To alleviate this dilemma, a generic approach to liquefied polysaccharides‐based polymers is proposed, resulting in a polysaccharide fluid with a tunable condensed state structure (solid‐gel‐liquid). Polysaccharide biobased fluids materials transcend the limits of the physical state of the biobased material itself and can even create completely new properties (different processing methods as well as functions) in a variety of polymeric structures. Considering the solvent incompatible high and low‐temperature applications, this method will have a great influence on the design of nanostructures of biomolecular derivatives and is expected to transform biomass materials such as polysaccharide biopolymers from traditional use to resource use, ultimately leading to the efficient use of biomass materials and their sustainability.

“…Amongst various conducting polymers, polyaniline (PANI) is known to be one of the most promising active materials owing to its easy synthesis, good environmental stability and high electrical conductivity . As shown in numerous reports, PANI has potential applications as electrode material in energy storage, electromagnetic shielding material in biosensors, anticorrosion coatings and so on . However, it is difficult to meet the requirements in all industries with PANI alone.…”

Polyaniline (PANI)/Ce 3+ and PANI/Ce 4+ composites were successfully prepared by in situ polymerization in an aqueous solution of poly(2-acrylamido-2-methylpropane sulfonic acid) and characterized by Fourier transform infrared spectroscopy, ultraviolet-visible spectroscopy, X-ray photoelectron spectroscopy, SEM, TEM and electrochemical methods. The results showed that the PANI/Ce ion composites had a high degree of sphericity, high electrical conductivity and good electrochemical performance. The conductivity of PANI/Ce(NO 3 ) 3 reaches a maximum of 46.76 S cm −1 at 20 wt% of Ce(NO 3 ) 3 . It is increased by 377% by comparison with that of pure PANI. In particular, the polarization results showed that the corrosion current density (0.47 A cm −2 ) and the inhibition efficiency (97%) of PANI/Ce(NO 3 ) 3 were better than the results for PANI and PANI/Ce(SO 4 ) 2 composite. This suggested that the PANI/Ce(NO 3 ) 3 composite has promising applications in conductive materials, anticorrosion coatings and other related fields.

“…Compared with traditional nanofluids, novel self-suspended nanomaterials at room temperature through covalent graft a soft organic corona onto the nanomaterials surface have been proved to enhance the manipulation and impart compatibility of nanoparticles (Huang et al 2016;Li et al 2015;Lei et al 2008;Zheng et al 2016;Warren et al 2006). Organic corona generally refers to a surfaceactive agent, in which one end can tether nanoparticles and the other can further bond with polymers.…”

Considering the excellent solubility of pyrrolidone ring organic compounds, the synthesized N-(trimethoxysilyl) propyl-N-methyl-2-pyrrolidone chlorides was tethered onto titanium dioxide (TiO 2 ) nanoparticles to improve dispersion of TiO 2 , and then polyethylene oxide (PEO) oligomer through ion exchange embraced the tethered TiO 2 to obtain a novel self-suspended hairy TiO 2 nanomaterials without any solvent. A variety of techniques were carried out to illustrate the structure and properties of the self-suspended hairy TiO 2 nanomaterials. It was found that TiO 2 nanoparticles embody monodispersity in the hybrid system though the ''false reunion'' phenomenon occurring due to nonpermanent weak physical cross-linking. Remarkably, self-suspended hairy TiO 2 nanomaterials exhibit lower viscosity, facilitating maneuverable and outstanding antifriction and wear resistance properties, due to the synergistic lubricating effect between spontaneously forming lubricating film and nano-lubrication of TiO 2 cores, overcoming the deficiency of both solid and liquid lubricants. This make them promising candidates for the micro-electromechanic/nano-electromechanic systems (MEMS/NEMS).
