本發(fā)明還提供一種上述方法制備得到的載硒的介孔二氧化硅納米材料。本發(fā)明還提供一種上述方法制備得到的載硒的介孔二氧化硅納米材料的應用。本發(fā)明采用溶膠-凝膠方法制備得到介孔二氧化硅(msns)，并進一步利用化學刻蝕法處理獲得一種較大孔徑的介孔二氧化硅，然后通過超聲輔助-熔融滲透方法(ultrasonicationassisted-meltinfiltration，ua-mi)負載高量納米硒(se)，超聲條件下將抗壞血酸溶液迅速滴加入硒源和擴孔的介孔二氧化硅溶液中反應，得到混合溶液，然后將混合溶液冷凍干燥，煅燒，這樣可以使納米se充分填充在孔道內(nèi)，從而負載高量納米硒，由于納米se充分填充在孔道內(nèi)，可達到緩慢持久的釋放效果。本發(fā)明制備的擴孔的msns平均孔徑和孔容分別為，將其作為載體負載納米硒se得到的se-msns，其中含硒量比較高可達45wt.％，且負載量在5wt.％-45wt.％可精確調(diào)控，粒徑為119±4nm。本發(fā)明中se-msns功能單元結構穩(wěn)定、尺寸可控、具有良好的分散性，更重要的是可以利用更少量的msns負載更多量的se，提高了納米se的負載率和msns的利用率。有益效果本發(fā)明獲得的se-msns具有載硒量高、可調(diào)控性強，分散性好，顆粒均一，se可以充分填充在msns的孔道中。相較于純se。</p><p> 待脫脂工序完成后放入草酸溶液中進行陽極氧化處理，在制作的過程中，需要使用3％-25％的草酸溶液中，將電壓控制在40-60v內(nèi)，電流1-2a/dm2的范圍內(nèi)，操作流程的溫度為40-65攝氏度，并且整體陽極氧化處理時長為40-60分鐘。經(jīng)陽極氧化處理后的陽極氧化層的厚度為3μm以上，并且該氧化層為黃色的。待陽極氧化處理完成后，金屬單質鋁的表面部分出現(xiàn)大量微孔，利用覆膜機將流延膜貼合在含有大量微孔的金屬單質鋁表面，用于將微孔與空氣進行隔絕，包裝后即可完成出廠。運輸至所需進行深加工的工廠，后續(xù)深加工的工廠確定好印刷方案后，將陽極氧化金屬單質鋁包覆的流延膜撕離后，將陽極氧化金屬單質鋁放置在加熱至20攝氏度的平板打印機上進行印刷。待印刷過程結束后，通過沸水封閉處理方式將金屬單質鋁表面的微孔進行封閉后，得到陽極氧化金屬單質鋁印刷后的產(chǎn)品。實施例8：選取待處理的鋁合金，將鋁合金放入弱堿性脫脂溶劑(弱堿性脫脂劑，廠商：嵊州市春凱新材料有限公司)進行脫脂處理，待脫脂工序完成后放入磷酸溶液中進行陽極氧化處理，在制作的過程中，需要使用10％的磷酸溶液中，將電壓控制在10-12v內(nèi)，操作流程的溫度為23-25攝氏度，并且整體陽極氧化處理時長為20-130分鐘。封孔劑哪家性價比高，詳情可以訪問百事德。</p><div
