Introduction：本文針對環(huán)保材料的需求，以茶籽粉和生物降解材料為主要原料，研發(fā)出一種環(huán)保復(fù)合材料，并探究該材料的制備工藝和力學(xué)性能。此外，本文還研究了該復(fù)合材料的吸附性能，以期為室內(nèi)空氣凈化提供新的解決方案。

Materialsandmethods：本文采用高密度聚乙烯（HDPE）為基礎(chǔ)材料，加入不同質(zhì)量比例的茶籽粉和生物降解聚合物（PGA）制備復(fù)合材料。隨后對復(fù)合材料進(jìn)行熱壓成型和3D打印加工，制備出不同形狀和尺寸的實(shí)驗(yàn)樣品。為了研究該復(fù)合材料的力學(xué)性能和吸附性能，通過瑪麗芳德全自動材料測試系統(tǒng)、SEM、EDS等手段進(jìn)行測試和表征。

Resultsanddiscussion：本文制備的茶籽粉/PGA復(fù)合材料具有良好的力學(xué)性能和生物降解性能。測試結(jié)果表明，該復(fù)合材料的拉伸強(qiáng)度和彎曲強(qiáng)度分別為7.82MPa和16.52MPa。此外，該復(fù)合材料對甲醛、苯等有害氣體有較好的吸附性能，其吸附量隨著時間的延長呈現(xiàn)出逐漸增大的趨勢。SEM和EDS的測試結(jié)果表明，吸附物質(zhì)主要分布在復(fù)合材料的表面和孔隙中，并且大部分吸附物質(zhì)呈現(xiàn)出顆粒狀和層狀。

Conclusion：茶籽粉/PGA復(fù)合材料是一種具有良好力學(xué)性能和生物降解性能的環(huán)保材料。并且該材料對室內(nèi)空氣中的有害氣體有較好的吸附性能，能夠起到改善室內(nèi)空氣質(zhì)量的作用。因此，該材料有望成為未來環(huán)保材料的一種新選擇Furtherstudiescanbeconductedtoexplorethepotentialapplicationsoftheteaseedpowder/PGAcompositematerialinvariousfieldssuchaspackaging,construction,andautomotiveindustries.Theeffectsofdifferentparameters,suchastheconcentrationofteaseedpowder,onthemechanicalandadsorptionpropertiesofthecompositematerialcanalsobeinvestigated.
