The imide oligomers were soluble in aprotic polar solvent of more than 35 wt%.
Fibers possessed bonded structures and the average fiber diameter was in the range of 5-6 [micro]m when fabricated in polar aprotic solvents, such as MEK and THF.
It has been realized that cations are solvated with polar groups on the polymer chains in polymer salt complexes whereas anions usually interact weakly with the aprotic host (7).
N] reactions proceed faster in aprotic solvents, such as DMF and DMSO, than in protic solvents, such as water and alcohol.
LiBOB meets a number of criteria required of salts for lithium-ion cells: (i) ability to form a stable solid electrolyte Interphase (SEI); (ii) good stability over a wide potential window; (iii) acceptable solubility in alkyl carbonate solvents such as ethylene carbonate (EC), propylene carbonate (PC), and so forth; (iv) high conductivity in various aprotic solvents; and (v) ability to sustain good cycling.
Usually, aromatic polyimides are prepared by the reaction of aromatic diamines and aromatic dianhydrides in polar aprotic solvents to give the polyimide precursors, polyamic acids, which are then chemically or thermally imidized to yield the corresponding polyimides [1, 5].
The general principle of molecular imprinting is as follows: (1) Specific complex formed based on (non)-covalent bonding interactions between template molecule and polymerizable functional monomer in an apolar and aprotic solvent before polymerization by assembling the functional monomers around the template molecule; (2) A rigid and porous copolymer yields in the presence of crosslinker and initiator; (3) The distinct cavities remains in the copolymer with the removal of the target template, which is tailor-made complementary to the template molecule in size, shape and functionality.
Aprotic and protic solvents interact differently with the polymer chain, the latter induce better planarity of the PAs chains which results in a bathochromic shift of the PL band maximum.
