Self-Generation of a Nanofibrous Structure Enables Facile Preparation and Processing of a Liquid Crystalline Polymeric Composite with Intrinsic Flame Retardancy

“…For instance, poly­( p -phenylene terephthalamide) was applied to reinforce nylon or poly­(4-vinylpyridine). , Only when the LLCP was lower than its critical concentration (<5 wt %) could a homogeneous phase be obtained with increased glass transition temperatures ( T g ) from 150 to 157 °C. This investigation indicated that the concentration of LLCP reinforcement was crucial for the preparation and performance of composites . Another method to fabricate liquid crystalline polymeric composites was melt blending thermotropic liquid crystalline polymers (TLCPs) with a thermoplastic (e.g., PP, PA) or thermosetting matrix (e.g., epoxy resin). − With an increase in the amount of TLCP, the phase separation between TLCP and the matrix became serious.…”

Morphology and Structure of Rod/Coil Nanocomposite Thin Film

“…Hydrogen bonds were used by Cowie et al [5] to enhance miscibility between poly(benzimidazole) (PBI) and poly(vinyl acetate-co-vinyl alcohol). More thermally stable ionic interactions were utilized to achieve rigid rod molecular composites [6][7][8][9].…”

Physical properties of epoxy resin self‐reinforced with organic rigid‐rod compounds

“…Nanocomposites often possess a number of advantages over their related macrocomposites, including the use of smaller amounts of the nanoscale dispersion [9,10], and excellent high- [11] and slow-speed-resistance properties [12,13]. Ionic molecularly modified composites have been prepared by mixing salt-type rigid-rod molecules with a polymer matrix in a cosolvent; the mechanical properties of such composites increased upon increasing the degree of rigi-rod reinforcement [14][15][16].…”
