“一種含銅抗菌高分子復合材料及其制備方法和應用” 發明專利獲得授權
近日,廈門福(fu)納(na)新材(cai)料科技有限公司(si)申報的發(fa)明專利 “一種含銅抗菌高(gao)分子(zi)復合材(cai)料及其制備(bei)方法(fa)和應(ying)用” 獲(huo)國家知識產權(quan)局(ju)授權(quan)(專利號:ZL 2021 1 1434287.5),開啟富勒烯在抗菌材(cai)料方面的應(ying)用。
亞(ya)銅(tong)(tong)具有(you)良好(hao)的抗(kang)菌(jun)(jun)、抑(yi)菌(jun)(jun)和(he)殺(sha)菌(jun)(jun)活(huo)性(xing)(xing),被(bei)廣泛(fan)應(ying)用于各大消毒殺(sha)菌(jun)(jun)場景領(ling)域(yu)。然而,亞(ya)銅(tong)(tong)不穩(wen)(wen)定(ding)(ding),氧(yang)化(hua)(hua)(hua)(hua)亞(ya)銅(tong)(tong)在(zai)參與化(hua)(hua)(hua)(hua)學(xue)反(fan)應(ying)過(guo)程中(zhong)不能穩(wen)(wen)定(ding)(ding)存在(zai),易被(bei)氧(yang)化(hua)(hua)(hua)(hua)為(wei)二價(jia)銅(tong)(tong)離(li)子(zi)(zi)或者還原為(wei)銅(tong)(tong)單質(zhi),從而導致其失活(huo)。這極大地限制了亞(ya)銅(tong)(tong)類(lei)材(cai)料(liao)(liao)在(zai)抗(kang)菌(jun)(jun)殺(sha)菌(jun)(jun)領(ling)域(yu)的應(ying)用。本(ben)發明(ming)提供(gong)一(yi)種(zhong)在(zai)含銅(tong)(tong)抗(kang)菌(jun)(jun)高分子(zi)(zi)復合(he)材(cai)料(liao)(liao)添加(jia)富(fu)勒烯(xi)的制備方法,發揮(hui)富(fu)勒烯(xi)“電子(zi)(zi)緩沖(chong)”機制,穩(wen)(wen)定(ding)(ding)了化(hua)(hua)(hua)(hua)學(xue)反(fan)應(ying)過(guo)程中(zhong)活(huo)性(xing)(xing)物種(zhong)氧(yang)化(hua)(hua)(hua)(hua)亞(ya)銅(tong)(tong)的存在(zai),有(you)效(xiao)保證銅(tong)(tong)離(li)子(zi)(zi)抗(kang)菌(jun)(jun)功能材(cai)料(liao)(liao)的抗(kang)菌(jun)(jun)抑(yi)菌(jun)(jun)活(huo)性(xing)(xing)。另一(yi)方面,本(ben)發明(ming)將(jiang)穩(wen)(wen)定(ding)(ding)亞(ya)銅(tong)(tong)含量的銅(tong)(tong)離(li)子(zi)(zi)抗(kang)菌(jun)(jun)功能材(cai)料(liao)(liao)分散于樹脂中(zhong),由(you)于銅(tong)(tong)離(li)子(zi)(zi)的緩釋(shi)效(xiao)果和(he)富(fu)勒烯(xi)的細胞安全保護作用,抗(kang)菌(jun)(jun)性(xing)(xing)成(cheng)分從母粒(li)逐步釋(shi)放到介質(zhi)中(zhong),能夠實現長效(xiao)穩(wen)(wen)定(ding)(ding)抑(yi)菌(jun)(jun),并(bing)且含有(you)富(fu)勒烯(xi)的銅(tong)(tong)離(li)子(zi)(zi)抗(kang)菌(jun)(jun)功能材(cai)料(liao)(liao)包埋在(zai)復合(he)材(cai)料(liao)(liao)母粒(li)中(zhong),能夠使其不受外界環境因(yin)素的干擾,從而保持(chi)穩(wen)(wen)定(ding)(ding)的抗(kang)菌(jun)(jun)抑(yi)菌(jun)(jun)活(huo)性(xing)(xing)。
本發明進一步拓展(zhan)了富勒烯在(zai)抗菌技術中(zhong)的應(ying)用領(ling)域,相對于傳統(tong)的直(zhi)接(jie)利用銅管或者銅片對水體進行殺菌消毒(du),具有應(ying)用場景(jing)更(geng)(geng)廣泛,投料更(geng)(geng)簡(jian)便(bian),使用更(geng)(geng)靈(ling)活等優勢。
