Image of FIG. 1.
FIG. 1.

Polymer nanowires created by TPP of resin, which are designed into spring shape. (a) Optical microscopic image of the nanosprings. The top spring is being stretched, and the bottom spring has been relaxed and restored to the original position. (b) The tensile strain curves of the nanosprings, from which a linear dependence is found. The insets illustrate how a spring was pulled.

FIG. 2.

Laser power dependent behaviors of nanosprings. (a) Spring constants from nanosprings of the same design as that in Fig. 1(a) but written by different laser powers. (b) Radius of the nanowires of each spring. Squares and circles show the half of lateral and vertical lengths. Triangles show averaged radius calculated from lateral and vertical lengths. (c) Shear modulus of nanosprings calculated with the value shown in (a) and (b) and the inset are SEM images of the springs.

Image of FIG. 3.
FIG. 3.

(a) Raman spectra of photopolymerized and unpolymerized resins. The peak at assigned to stretching mode from unsaturated monomer and oligomer molecules disappears after polymerization. (b) Intensity of peak in polymers solidified at different laser powers. The upper and lower dotted straight lines are the intensity from the unpolymerized resin and that fully polymerized under UV light exposure.

Image of FIG. 4.
FIG. 4.

Saturated spring constants by exposing the nanosprings with additional UV light for different durations, which were written by TPP and then immersed into ethanol.
