N‐doped C‐dot embedded fluorescent and thermo‐responsive p(NIPAAm) microgel composites

Abstract

In this study, the synthesis of N-doped C-dot embedding poly(N-isopropylacrylamide) (p(NIPAAm)) particle composites via surfactant-free emulsion polymerization technique was reported. The fluorescent property of N-doped C-dot combined with thermo-responsive properties of p(NIPAAm) particles (p(NIPAAm)/C-dot) render smart materials with intriguing properties. The particle size and volume phase transition temperature (VPTT) values of p(NIPAAm) based particles was altered in accord with the amount of embedded N-doped C-dot within p(NIPAAm) particles between 1,000-750 nm and 35.4-37.2 C, respectively. On the other hand, N-doped C-dot within p(NIPAAm) particles was afforded fluorescent properties with emission peak at around 460 nm. The effect of the amount of N-doped C-dot within p(NIPAAm) particles, temperature and pH were investigated on the fluorescent properties of N-doped C-dot embedded p(NIPAAm) particle composite. POLYM.

Enhanced mechanical and thermal properties of carbon fiber‐reinforced thermoplastic copoly(phthalazinone ether sulfone ketone) composites

“…After SiC NWs were introduced, SiC NWs act as secondary reinforcements to reinforce the resin matrix (see Figure 6A), which greatly enhanced the resin matrix's toughness and improved the transfer of stress to the resin matrix. [ 28 ]…”

“…After SiC NWs were introduced, SiC NWs act as secondary reinforcements to reinforce the resin matrix (see Figure 6A), which greatly enhanced the resin matrix's toughness and improved the transfer of stress to the resin matrix. [28] On the other hand, SiC NWs migrated to the CF surface during hot-pressing (as shown in Figure 6B), which improved the stress transfer effect and interfacial properties between CF and PPBESK. In addition, as shown in Figure 6C, many pores and the pull-out of SiC NWs could be observed, which meant that it could absorb more energy during the fracture process, resulting in improved the composite interlaminar properties.…”

Effects of temperature distribution caused by energy accumulation on the bonding properties of carbon fiber composite components

“…For CFRP parts, if damage such as cracks is detected, the damaged parts should be replaced or repaired. [ 3 ] Maintenance takes precedence for cost reasons and to reduce maintenance delays. [ 4 ] However, CFRP laminates are not compatible with the conventional welding which is suitable for metals.…”
