“…Although, many EM shielding methods [2][3][4][5][6][7][8][9][10] are available for electronic plastic packaging, not many methods are available for optical-electronic plastic packaging. Low cost, high EM shielding optical laser modules made with the modified thermosets using compression molding technology were reported [5,11].…”

“…Low cost, high EM shielding optical laser modules made with the modified thermosets using compression molding technology were reported [5,11]. Instead of using compressing molding, a systematic investigation on the EM shielding effectiveness (SE) of nylon66 or LCP composites using injection molded thermoplastic packaging was conducted in the author's previous work [2][3][4].…”

“…It is well known that metallic package provides excellent shielding effectiveness (SE). However, owing to its low cost nature and ease of manufacture, plastic composite package technology has been considered to be one of the major choices for reducing the costs of fabricating optical transceiver modules for use in the fiber to the home (FTTH) applications [3]- [7]. Plastics alone are inherently transparent to electromagnetic (EM) radiation and provide no shielding against radiation emissions.…”

“…Recently, several types of plastic composite package for the optical transceiver modules have been demonstrated with effective EM shielding ability. These plastic composites are the nylon and liquid crystal polymer (LCP) reinforced with carbon fibers [10]-[1 1], and the woven continuation fiber (WCCF) [3], [7], and [12].…”

Electromagnetic (EM) shielding performance for a plastic composite by employing polyimide-based dispersive multiwall carbon nanotubes (MWCNTs) is presented. A well-dispersed MWCNT composite offers a higher electrical conductivity with a lower weight percentage of MWCNTs. The dispersive MWCNT composites with their high shielding effectiveness (SE) are suitable for packaging low-cost optical transceiver modules used in fiber to the home (FTTH) lightwave transmission systems.

Novel foam composites comprising functionalized graphene (f‐G) and polyvinylidene fluoride (PVDF) were prepared and electrical conductivity and electromagnetic interference (EMI) shielding efficiency of the composites with different mass fractions of f‐G have been investigated. The electrical conductivity increases with the increase in concentration of f‐G in insulating PVDF matrix. A dramatic change in the conductivity is observed from 10−16 S · m−1 for insulating PVDF to 10−4 S · m−1 for 0.5 wt.% f‐G reinforced PVDF composite, which can be attributed to high‐aspect‐ratio and highly conducting nature of f‐G nanofiller, which forms a conductive network in the polymer. An EMI shielding effectiveness of ≈20 dB is obtained in X‐band (8–12 GHz) region and 18 dB in broadband (1–8 GHz) region for 5 wt.% of f‐G in foam composite. The application of conductive graphene foam composites as lightweight EMI shielding materials for X‐band and broadband shielding has been demonstrated and the mechanism of EMI shielding in f‐G/PVDF foam composites has been discussed.
