概要	The current system of disposal of plastic materials fabricated from petroleum-based resources causes serious environmental pollution. To solve the problem, a bioplastic called “cell-plastic” is developed, in which unicellular green algal cells serve as a fundamental resource. This approach converts CO2 in the atmosphere directly into plastic products by exploiting the photosynthetic-driven proliferation of algal cells. Herein, cell-plastic films are fabricated using biodegradable and water-soluble polyvinyl alcohol (PVA) as a matrix, in which the effects of a cell-to-matrix mixing ratio and the chemical structure of the matrix on the mechanical and thermal properties are investigated. As a method of the chemical structural change, a cross-linking structure is introduced to the matrix by connecting hydroxy groups of PVA using aldehyde. The tensile tests reveal that the PVA-cell-plastic film maintains the mechanical properties of PVA film. Moreover, a cross-linked cell-plastic film exhibits high water absorption, making it suitable as a functional cell-plastic material.
