Natural Rubber Latex Membranes (NRL) extracted from the Hevea brasiliensis, has been of great importance in areas such as medicine and bioengineering, due to latex ability to stimulate angiogenesis, cell adhesion and the formation of extracellular matrix, besides acting as a physical barrier to infectious agents, characteristics which makes it interesting for applications such as prostheses and medical grafts. The biodegradability of biomaterials is a major factor for its users do not require medical intervention to remove them. However, the biodegradability of latex is not significant when compared to other polymers used for the development of materials with biomedical applications. This project aims to improve the biodegradability and subsequent bioabsorption latex membranes associating them with the polylactic acid, a polymer which has properties such as bioresorbability and biocompatibility, in addition to biodegradability, low toxicity and low cost is the most studied in biomedical, pharmaceutical and environmental fields. The membranes will be characterized by tests of Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR), mechanical strength, mass loss, permeability and biological characterization by indirect cytotoxicity (MTT), which cover the biological, chemical and physical fields.
