Density, water, and swelling characteristics of cellular palm kernel oil bio‐polyol modified polyurethane toward more sustainable growing media application
Abstract:Developing a bio‐based polyol polyurethane foam with the desired properties for use as growing media for green vertical walls could be beneficial in the quest to create a more sustainable urban living. In this work, palm kernel oil‐based polyol (PKOP) was mixed with petroleum‐based polyol (PP) at different ratios in synthesizing polyurethane foam. The impacts of PKOP/PP formulation on the density, cell morphology, water absorption, water retention, swelling behavior, and their chemical functional groups were e… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
