Abstract

In this study, PLA scaffolds was manufactured by using PLA mesh fabric for tea-bags, and the effects of hot press temperature on mechanical properties, morphology, and cell viability were investigated. Research was focused on whether PLA mesh fabric for tea-bags can be used as a scaffold. PLA scaffolds were manufactured by laminating five layers of PLA mesh fabric that rotated at a 45 degree angle and the layers are hot pressed at 120, 130, 140, and 150 ℃. As the hot press temperature increased to 140 ℃, the tensile strength increased. SEM photographs showed that micro pores were formed well at 120 and 130 ℃. Non-toxicity and biocompatibility of the PLA mesh scaffold were revealed via MTT assay for cell viablity and DAPI staining experiments. We developed PLA scaffolds made of mesh fabric and showed the possibility thereof as scaffolds.
