The self-consistent field theory was employed to numerically study the interaction and interpenetration between two opposing weak polybase brushes. The grafted chains in the gap between the two grafting substrates retract and tilt in order to reduce the unfavorable electrostatic and steric repulsions between the two opposing brushes.

Nonconventional luminescent polymers exhibit remarkably high luminescence efficiency, reaching up to 9.2% in dilute solutions (0.1 mg/mL), and their optical properties are highly responsive to a range of variables, including pH, excitation wavelength, concentration, temperature and metal ions. Due to these unique optical properties and their good biocompatibility, these materials have emerged as a promising class of materials for cell imaging applications.

In this work, a cross-electrospinning with heat treatment strategy to obtain a composite separator (PI/oPAN) randomly interwoven by PI and pre-oxidized PAN (oPAN) nanofibers was proposed. PI/oPAN separator reconcile high porosity with superior mechanical strength because of the formation of a PI fibrous network adhered by the oPAN component. Moreover, obtained PI/oPAN separator presented high ionic conductivity and Li⁺ transference number, resulting in a desirable and stable cell cycling performance.

Using molecular dynamics simulation, we investigate the nonlinear rheological behavior of semi-flexible entangled polymer melts. Our findings show a notable stress overshoot phenomenon at specific shear rates, along with the observation of rare metastable states, indicated by a dual-plateau pattern in the shear stress-strain curve.

Comparative analysis of the influence of intrachain and interchain cross-linking structures on the dielectric of PI. Remarkably, PI films with an intrachain cross-linking structure exhibit a lower dielectric constant and dielectric loss compared to PI films with an interchain cross-linking structure.

The NR/SBR sample was lightly crosslinked with CB and cut apart, then, healed at 80°C and 0.6 MPa. Finally, free-chain interdiffusion facilitates self-healing within an hour. The maximum self-healing performance was 40% for 25/75 phr of NR/SBR. Additionally, wet grip at 0ºC and rolling resistance at 60ºC result in optimal energy savings.
