Lớp phủ Titanium Dioxide được chuẩn bị bằng phương pháp phun plasma từ dung dịch huyền phù
Tóm tắt
Lớp phủ Titanium dioxide được chuẩn bị từ dung dịch titanium isopropoxide chứa các hạt nano TiO2 bằng cách sử dụng quy trình phun plasma. Các ảnh hưởng của khoảng cách phun đến thành phần và vi cấu trúc của lớp phủ đã được nghiên cứu và so sánh với các dung dịch tiên tố nguyên chất và huyền phù TiO2 dựa trên nước. Kết quả cho thấy rằng hàm lượng anatase của lớp phủ tăng lên khi khoảng cách phun tăng và tỷ lệ lắng đọng giảm khi khoảng cách phun tăng. Các hạt nano anatase trong dung dịch đã được đưa vào lớp phủ mà không có sự biến đổi pha trong khi phần lớn TiO2 trong dung dịch tiên tố đã chuyển đổi thành rutile. Vi cấu trúc của các hạt anatase được bảo tồn được gắn kết bởi rutile đã cải thiện hiệu suất lắng đọng của lớp phủ. Lượng pha anatase có thể được điều chỉnh bằng cách thay đổi tỷ lệ giữa dung dịch với hạt nano anatase TiO2 được thêm vào.
