英文摘要:
Highly soluble polyacrylonitrile(PAN)-covalently grafted MoS2 nanosheets (MoS2-PAN) were synthesized in situ through reversible addition fragmentation chain transfer (RAFT) polymerization. In comparison with MoS2 and the MoS2/PAN blends, whether in solution or in a PMMA matrix, the MoS2-PAN-based samples show superior optical Limiting response in the visible and near-infrared ranges. After annealing at 200 degrees C in N-2 for 4 hours, the annealed MoS2-PAN/PMMA film exhibits significantly enhanced nonlinear opticaL and opticaL Limiting responses when compared to the non-annealed MoS2-PAN/PMMA film. The observed nonlinear coefficients of the MoS2-PAN/PMMA film are changed from 1015 cm GW(-1) at 532 nm and 534 cm GW(-1) at 1064 nm before annealing to 1151 cm GW(-1) at 532 nm and 699 cm GW-1 at 1064 nm after annealing. The Limiting thresholds were also decreased from 1.98 J cm(-1) at 532 nm and 3.60 J cm(-1) at 1064 nm before anneaLing to 1.56 J cm(-1) at 532 nm and 2.67 J cm(-1) at 1064 nm after annealing.
