Abstract

original image

The inside cover shows that polymer gels composed of poly(N-isopropylacrylamide) and carbon nanotubes (CNTs) exhibit a repeatable volume phase transition between shrinkage and swelling upon ON/OFF near-IR laser-light irradiation in the presence of water. The volume changes, triggered by the photothermal effect of CNTs, are repeatable for more than 1200 cycles. In their Communication on p. 3610, Tsuyohiko Fujigaya, Naotoshi Nakaashima, and co-workers emphasize that one of the great advantages of utilizing CNTs in this system is their high durability.
