A urinary system catheter is covered by an ethanol extract of propolis on a surface of the urinary system catheter. The EEP is used as a coating material of the urinary system catheter to prepare an antimicrobial urinary system catheter. The EEP serving as a surface coating can enhance surface hydrophilicity of the urinary system catheter, and clinical operation of the urinary system catheter is facilitated. Meanwhile, the EEP serving as the surface coating can prevent a bacterial biofilm from being formed on the surface of the urinary system catheter, thereby possessing antimicrobial and anti-infective effects, and a high anti-scab capacity. In addition, propolis is a natural substance, has the advantages of good biocompatibility and low cost, and is suitable for mass production. The urinary system catheter prepared by using the EEP as the coating has a good application prospect.

The invention relates to a biocomposite comprising beeswax and a method of producing the biocomposite with the use of beeswax. The use of beeswax made it possible to eliminate/replace synthetic (petroleum-derived) waxes used as a processing additive and reduce the carbon footprint of the composite.
