Fig. 3: Dependence of PBA-CTA degree of polymerization (Xn) and PBA-CTA loading (wt%) on the surface morphologies of 3D printed materials.

From: Nano- to macro-scale control of 3D printed materials via polymerization induced microphase separation

Fig. 3

a–e 16.5 wt% PBA-CTA with PBA-CTA Xn = a 24, b 48, c 94, d 180, and e 360; f–j 28.2 wt% PBA-CTA with PBA-CTA Xn = f 24, g 48, h 94, i 180, and j 360; k–o 43.9 wt% PBA-CTA with PBA-CTA Xn = k 24, l 48, m 94, n 180, and o 360. PBA and net-P(AA-stat-PEGDA) domains are shown in dark brown and light brown, respectively. Materials were 3D printed using a molar ratio of [AA]/[PEGDA] = 4/1 at a fixed wt% of PBA-CTA and subsequently analyzed by AFM to obtain PeakForce QNM modulus map images. Scale bars are 60 nm. Note: Higher magnification of a, f, and k are shown in Supplementary Fig. 9.
