Several fully green composites are prepared by taking the tea polyphenols (TP) with various percentages to blend with poly(vinyl alcohol) (PVA). The as‐prepared PVA/TP composite with only 5% TP shows superb anti‐UV properties even after water washing, the presented UV protection factor (UPF) value is still greater than that of the standard values reported by Australia and New Zealand (AS/NZS 4399‐1996). Moreover, the UPF value of those PVA/TP composites is found capable of furthermore enhancement by increasing the TP percent. This PVA/TP composite also shows good antibacterial and biodegradability while it is kept with certain mechanical properties to fit required application cases.

完全绿色的聚乙烯醇/茶多酚复合材料以及超强的紫外线和细菌特性

通过将各种百分比的茶多酚（TP）与聚乙烯醇（PVA）混合，可以制备几种完全绿色的复合材料。制备的仅含5％TP的PVA / TP复合材料即使在水洗后也显示出卓越的抗UV性能，目前的UV保护系数（UPF）值仍大于澳大利亚和新西兰报告的标准值（AS / NZS 4399-1996）。而且，发现那些PVA / TP复合材料的UPF值能够通过增加TP百分比而进一步提高。这种PVA / TP复合材料还具有良好的抗菌和生物降解性，同时具有一定的机械性能，可满足所需的应用场合。
