Mechanical reinforcement with enhanced electrical and heat conduction of epoxy resin by polyaniline and graphene nanoplatelets

Abstract: Abstract In this study, the effects of polyaniline (PANI) incorporation (3 wt% of PANI) and graphene nanoplatelets (GNPs) loading (0.1–0.7 wt%) on the mechanical, thermal, and electrical performance of epoxy matrix were investigated. The incorporation of 0.3 wt% GNPs optimally enhanced the bending strength, bending modulus, tensile strength, tensile modulus, and impact strength (90 MPa, 1422 MPa, 63 MPa, 602 MPa, and 8.29 kJm−2, respectively). At 0.3 wt% GNPs, the hybridization effect optimally enhanced the glass transition behaviour of the epoxy nanocomposites. The electrical and thermal conductivities of epoxy were improved upon the inclusion of PANI, and this increase was further augmented when the GNPs content increased to 0.3 wt%. However, higher GNPs contents deteriorated the mechanical performance and electrical and heat conduction. Field emission scanning electron microscopy showed good filler distribution and effective interactions among the GNPs, PANI, and epoxy components with appropriate compositions.

Design segmented slot waveguide for integrated waveguide modulator

Abstract: In this article, segmented slot waveguide structures are designed and analysed numerically. We present a theoretical investigation of overlap factors and low half voltage for different segmented slot waveguide structures to determine optimised geometrical dimensions based on slot widths. Results shows that high overlap factor, and low half voltage, occurs for 200 and 300 nm periodicities at a 100 nm slot width, while for a 400 nm periodicity this width is 125 nm. Thus, achieving a very low V π compared to conventional slot waveguides demonstrates a high sensitivity of segmented slot waveguide and unprecedented sensing in a sensor application.
