The groups of biopolymer coatings.There are several enviable attributes of titanium and its alloys that contribute to their popularity in biomedical devices and equipment, including their rather low modulus, excellent corrosion resistance, and biocompatibility, good machinability, formability, and strength comprehensive impact and fatigue. Nevertheless, titanium and its alloys do not meet all medical requirements due to its unique properties and alloys, so surface modifications must be made to enhance mechanical, chemical, and biological characteristics. As a review of biomedical engineering, this article discusses specific polymers for coating applications as well as various polymer coatings for functionalization improvements. The versatility of biopolymer coatings makes them extremely appropriate for a broad range of biological uses. To enhance the engineering of tissue and drug delivery, this study summarized and analyzed the most recent advances in biopolymer coatings. Surface qualities of polymer coatings can be adjusted to meet specific criteria for various biomedical applications or integrated with new capabilities. Moreover, polymer coatings containing different inorganic ions can enhance the growth of tissue, proliferation of cells, healing, as well as the transfer of biomolecules, like active molecules, agents of antimicrobial, factors of growth, and medications.HighlightsSurface modification avenues of Ti materials as orthopedic replacements are critically reviewed.Basic descriptions of titanium and titanium alloys are presented.Advances in the corrosion behavior of biomedical titanium alloys are thoroughly scrutinized.Fundamental methods based on mechanical, physical, and chemical principles for biopolymer coatings are particularly presented.Main biopolymer coatings types that are used on titanium surfaces are reviewed.
