Abstract
The preparation of useful products based on the integration of carbon dioxide fixation and biomass utilization is important for the future development of environmentally harmonized materials technologies. Here we report the use of supercritical carbon dioxide and spin-coated cellulose/chitosan matrices to produce biopolymer films infiltrated with densely packed calcium carbonate (vaterite) particles. Composite films of high uniformity are prepared specifically in the presence of low concentrations of polyacrylic acid.Keywords
