“…Furthermore, an unexpectedly hydrophobic water contact angle (WCA) of silica colloidal crystals on PDMS was found. Additional experiments demonstrated that the transportation of hydrophobic content in PDMS to the surface is responsible for changing the surface wettability, which agrees with reports in literatures of the migration of uncrosslinked molecules in PDMS [20,21]. These findings have profound implications since many polymers contain mobile species; the migration of these mobile components would influence the properties of photonic crystals formed on the surface.…”

“…PDMS is widely used to prepare elastic stamps with patterns on the surface 57 , 58 . However, stamps prepared by traditional PDMS lack the ability of reconstruction, thus recyclable PDMS stamp would be preferred from both economic and operational view 59 . Here, the PDMS elastomer prepared could be used repeatedly as a stamp material, as shown in Fig.…”

This article reports preparation of a crosslinked polydimethylsiloxane (PDMS) network via dynamic transesterification reaction between PDMS-diglycidyl ether and pripol 1017 with Zn(OAc)2 as the catalyst. The thermal dynamic nature of the network was investigated by the creep-recovery and stress-relaxation tests. The synthesized PDMS elastomer showed excellent solvent resistance even under high temperature, and could be reprocessed by hot pressing at 180 °C with the mechanical properties maintained after 10 cycles. Application of the PDMS elastomer in constructing micro-patterned stamps repeatedly has been demonstrated. The high plastic temperature and good solvent resistance distinguish the research from other reported thermoplastic PDMS elastomers and broaden the practical application areas.

Tailoring the surface properties of poly(dimethylsiloxane) (PDMS) is essential for the advancement of its applications. However, the modification process is usually complicated and limited due to the chemical inertness of the surfaces of PDMS. Here, we report for the first time, a facile and versatile method for the functional surface modification of PDMS via visible light-induced grafting polymerization at room temperature. This modification is readily achieved in two steps: (1) covalently integrating alkyl bromine into the PDMS networks using a simple mixing procedure and (2) visible light-induced surface grafting polymerization using Mn 2 (CO) 10 . We have demonstrated that the PDMS surface can be functionalized with a wide variety of polymers via covalent grafting, such as poly(trifluoroethyl methacrylate) (PTFEMA), poly(N-isopropylacrylamide) (PNIPAAm), poly(acrylic acid) (PAA) and poly(vinyl acetate) (PVAc). As an example, after the grafted PVAc was transformed into its hydrophilic analogue poly(vinyl alcohol) (PVA), anti-biofouling functionalization of PDMS was obtained. The anti-biofouling properties of the functionalized PDMS were demonstrated using cell adhesion and bacterial adhesion tests. Moreover, the grafting kinetics of PVAc showed that this process was fast and efficient.
