Synopsis: Conventional syntheses of porous carbon fibers (PCFs) rely on blending PAN with sacrificial additives, which macrophase-separate and produce poorly-controlled pores. Herein we have utilized block copolymers for synthesizing PCFs with well-controlled bimodal mesopores and micropores, revolutionizing the synthesis of PCFs.

Synopsis: After attaching quadruple hydrogen-bonding UPy end groups, polyetherimides (PEI) with a Mw as low as 8 kDa exhibited outstanding mechanical strength (GPa level) comparable to high-molecular-weight state-of-the-art commercial PEIs. The UPy end group was thermally stable up to 240 °C.

Synopsis: Surprisingly, we found that the pore size and center-to-center spacing of mesoporous carbon thin films from PAN-b-PMMA increased significantly with annealing temperature, which is different from most block copolymers. The work provides a simple strategy to control the pore size of mesoporous carbon thin films by tuning the processing conditions instead of synthesizing block copolymers of various molecular weights and compositions.

Synopsis: After measuring and analyzing the sensitivities of >74 types of nanoparticles, we found that the aspect ratio (R) is the key parameter that controls the nanoparticle sensitivity (S) following an empirical equation, S = 46.87 R + 109.37. Other parameters including shape, size, composition, and cross-sectional area have little effect on sensitivity.
