Tổng hợp hạt bạc kiểm soát hình dạng thông qua tự lắp ráp của chất hoạt động bề mặt dưới bức xạ siêu âm
Tóm tắt
Nhiều phương pháp đã được đưa ra cho việc sản xuất hạt nano bạc. Một phương pháp mới đã được phát triển bao gồm tổng hợp hạt nano bạc kiểm soát hình dạng ở các hình dạng khác nhau. Các cấu trúc nhánh cây, lập phương, cầu và xốp được hình thành nhờ sự tự sắp xếp của chất hoạt động bề mặt như một khuôn dưới bức xạ siêu âm. Để sản xuất các hạt bạc, axit ascorbic đã được sử dụng để khử dung dịch nước của bạc nitrat trong sự hiện diện của muối natri dodecylbenzenesulfonic, poly(vinyl pyrrolidinone) và hỗn hợp các dung dịch hữu cơ và nước. Phân tích quang học điện tử quét và quang học điện tử truyền cho thấy hình dáng và kích thước của các hạt được sản xuất bị ảnh hưởng bởi loại tác nhân bao phủ, sự hiện diện của bức xạ siêu âm và thời gian tinh thể hóa. Để đo độ sần sùi của các hạt nhánh cây và xốp, một thiết bị phản xạ quang học đã được sử dụng. Các phân tử chất hoạt động bề mặt trong dung dịch nước có thể tập hợp thành các hình dạng khác nhau tùy thuộc vào nhiệt độ, tính chất ion của dung dịch, thời gian và hàm lượng dung môi không chứa proton.
