Abstract

This chapter discusses briefly the photoresponsive polymeric systems in general and the need for photoresponsive commodity polymers, followed by recent developments of photoresponsive polyolefins with suitable examples. Tremendous progress has been made in the fabrication of photoresponsive hydrogels and liquid crystalline networks (LCNs) with the development of next generation micro-devices that are capable of mimicking natural movements. Polyolefins can range from ultra-rigid thermosets to high-performance elastomers via all conceivable thermoplastic and elastoplastic materials in between. In order to make photoresponsive polyolefin-based micro-devices, researchers combined well-known responsive properties of LC materials with polyolefins. Apart from photoactuators based on polyolefins, photopattering, or surface micro-patterning of polyethylene (PE) films have wide range of applications including in optical recording, optical memory devices, sensors, biofouling, and tissue engineering. One of the major challenges to be addressed during the development of polyolefin- based photoresponsive materials is photo-oxidative degradation.
