This initial study revealed several interesting outcomes. First, low-power laser light from a 690 nm, 1.10 mW diode laser could be used to rapidly form spiked structures on the surface of Materials 1 and 2. Remarkably, the power density of the laser light on the surface of the polymer is approximately 1.4 kW/cm 2 , which is several orders of magnitude lower than typical modification of polymers with high power pulsed lasers. Because of the low power of this laser, it follows that poly(S-r-CPD) is particularly photo-sensitive to this irradiation. This is a unique response from a low-cost, readily accessible polymer. In contrast, control experiments indicated no observable modification after irradiation of a panel of common commercial polymer samples with this laser including ethylene-vinyl acetate, polysulfone, polytetrafluoroethylene, polyacetal, polypropylene, a phenoxy resin, nylon-6, polyethylene, polystyrene, and polycarbonate (S23-S24). Furthermore, the spiked structures formed on Materials 1 and 2 are persistent. This outcome may be due to the dynamic S-S bonds in polymers made by inverse vulcanization that impart vitrimer-like properties. The ability to alter polymer surface morphology and roughness has found wide ranging applications in adhesive technologies, antifouling surfaces, and substrates for cellular and tissue engineering, so the direct and rapid surface modification observed in Figure
