Methoxy-PEG-PU (mPEG-PU) is an AB-type amphiphilic block copolymer consisting of a hydrophilic soft segment (mPEG) and a hydrophobic/hard segment (PU). It integrates the biocompatibility of PEG with the mechanical strength and functional tunability of polyurethane, enabling pH-responsive and charge-reversible properties for intelligent drug delivery and biomedical applications

Methoxy PEG PU (mPEG PU) is a block copolymer composed of polyurethane (PU) as hydrophobic/hard segment and monomethoxypolyethylene glycol (mPEG) as hydrophilic/soft segment. It combines the biocompatibility of PEG with the mechanical properties and functional adjustability of polyurethane, making it an intelligent polymer with pH response and charge reversal characteristics.

Chinese name: pH responsive charge reversible fluorescent block polymer

English name: mPEG PU; Methoxy-PEG-PU

Core Performance and Advantages

Intelligent responsiveness: With pH responsive and charge reversible fluorescence properties, it can change its own properties according to environmental changes (such as the slightly acidic environment of tumor tissue), achieving targeted drug release.

Excellent biocompatibility: PEG segments provide good biocompatibility, low immunogenicity, and anti protein adsorption ability, which helps to prolong the circulation time of materials in vivo.

Adjustable mechanical properties: By changing the molecular weight of PEG, the composition and proportion of polyurethane hard segments, the flexibility, elasticity, and deformation recovery ability of the material can be precisely controlled.

Microphase separation structure: Hydrophilic PEG soft segments and hydrophobic PU hard segments undergo phase separation at the microscopic level, which endows the material with unique surface properties and dynamic reconstruction ability, contributing to long-term stability.

Good processability: It has good film-forming and processability, suitable for various molding processes, and provides a foundation for functional expansion.
