Superior nonlinear optical and optical limiting properties of cross-linked and thermally stable HiPCO-SWCNTs@PVA films

Preparation and characterization of CO2/O2 selective facilitated transport films by coating polyvinyl alcohol/polyethylene glycol/aminated sodium lignosulfonate on TiO2/ZnO‐modified LDPE

“…Compared with PVA/PEG coating, 1:2:2EDA/DEA‐Ls‐g‐AM coating shows a slight increase in Δ H m . The T m of the coatings after the addition of modified Ls shifted back slightly, which may be due to the plasticizing effect of aminated Ls, thereby improving the thermal stability of the coatings 46 . In conclusion, the thermal properties of the composite films do not change significantly, and a decrease in crystallinity is beneficial to improve gas permeability.…”

Conditions for the efficiency of optical limiting based on experiment and quantum chemical calculations

“…10 To protect the photosensitive matrices, it is advisable to use nonlinear optical (NLO) materials that allow increasing the maximum power of laser radiation, preventing the destruction of photosensitive elements. 11 In this case, limiting the level of energy fluxes within the specific range is achieved by passive optical limiters supplied with the NLO materials. 12 Nevertheless, despite the significant amount of work in this area, the creation of universal protection against laser radiation faces difficulties and gets stuck in an inordinate number of experiments, during which, through rather complex manipulations, it is sometimes possible to identify some primitive patterns that assist in optimizing the design of optical limiters.…”

Ограничение Мощности Лазерного Излучения Углеродными Материалами С Нелинейным Оптическим Пороговым Эффектом При Форме Импульса С Плоской Вершиной

“…При этом они охватывают большой диапазон длин волн [21,22]. Данные устройства способны увеличить максимально допустимую мощность лазерного излучения, чтобы не допустить разрушения камеры [23,24], светочувствительных детекторов и не нанести ущерб не защищенной сетчатке глаза [25,26].…”
