摘要: The invention discloses a modified polypropylene carbonate material and preparation method thereof. comprises the following components in percentage byweight: 98%-99.7% of 0.3%-2% polydopamine derivative. steps preparing derivative, then adding polydopaminederivative into matrix by solvent mixing. For provided invention, 5% weight loss temperature (T5%) at low content can be increased more than 30 DEG C comparison with pure carbonate; tensile strength reach 14 MPa or more, Young's modulus 700 which are significantly carbonate. prepared has characteristics excellent mechanical properties, thermal stability, environmental friendliness degradability, replace disposable universal plastics practical application, thereby greatly reducing white pollution.
