4. Conclusion
In summary, reinforced CS@MWCNTs/PLLA photothermal membranes obtained by
solvent-induced recrystallization are reported in this work. The
photothermal membrane exhibits a nanowrinkled structure with a high
specific surface area, which provides more light absorption and enhances
the photothermal effectiveness of the membrane. The photothermal film
can heat up instantaneously and maintain between 60~75˚C
at 800Wm-2 sun irradiation, which provides excellent
photothermal performance. The innovative solvent-induced
recrystallization procedure can greatly improve the mechanical
properties and micro-morphology of the electrospun membrane without
sacrificing the wearing comfort of the flexible membrane and is
potentially applicable to other electrospun membranes.
