Engineering PVDF/Graphene Hybrid Membrane for Non-Linear Optical Limiting Applications
Abstract
Optical power limiting, a nonlinear optical effect, can be exploited to protect the eyes and optical sensor from high power laser pulses. Due to its broadband absorption properties, graphene has been considered by many as an excellent optical limiting (OL) material. However it is difficult to fabricate graphene membrane with the required flexibility, transparency and stability needed for practical OL applications, especially when solution-processed graphene flakes are used as the OL material. In order to hold the graphene flakes together as a structurally stable film, one way is to synthesize a composite film consisting of graphene flakes and a transparent polymer which serves as the binder. Taking advantage of the excellent film forming properties of polyvinylidene fluoride (PVDF) and the strong non-linear optical (NLO) properties of its ferroelectric phase, the aim of this proposal is to fabricate and study the non-linear optical studies of PVDF/graphene membranes.
