Interferometric optical sensors based on porous silicon grafted with styrenic moieties for highly enhanced VOC detection.

ABSTRACT: The majority of volatile organic compounds (VOCs) are hazardous pollutants that pose significant risks to human health and the environment. Thus, the development of a smart sensing system for the early identification of VOCs would be in high demand, particularly those enabling rapid detection with high sensitivity and long-term stability. In this study, an interferometric optical sensor was rationally devised through the facile non-atmospheric thermolysis of polystyrene (PS) pre-loaded into a porous silicon (pSi) template prepared via electrochemical anodization. During the thermolysis, styrenic carbon fragments were covalently grafted onto the pore walls of pSi to form a PS-grafted pSi composite (pSi-PS). This composite was subsequently utilized as a scaffold for grafting poly(4-ch
