Nhựa PU; Hạt nano Cr2O3; Ngụy trang ảnh nhiệt.Tóm tắt
Nghiên cứu này trình bày quá trình chế tạo lớp phủ ngụy trang và đánh giá hiệu quả của lớp phủ ngụy trang. Lớp phủ được chế tạo trên cơ sở của hạt nano Cr2O3 và nhựa PU. Hạt nano Cr2O3 được tổng hợp bằng phương pháp đốt cháy với tiền chất là Cr(NO3)3.9H2O và glycine theo tỷ lệ glycine/NO3 là 9:1. Các hạt nano Cr2O3 tổng hợp được phân bố trong dải kích thước trong khoảng 40 - 60 nm và được phân tán đều trong lớp phủ trên bề mặt vải polyeste. Lớp phủ cho khả năng ngụy trang tốt trong thời gian dài trước camera ảnh nhiệt thế hệ thứ 3 không làm lạnh FLIR BHM-Series Bi-Ocular.
