Surface heat transfer measurement is an important aspect in many research problems. Thin film heat flux sensor (TFHFS) is mostly considered in such situations for heat flux measurement due to its quick response and high accuracy. In the present studies, multi-walled carbon nanotubes (MWCNTs) are mixed with platinum while making the TFHFSs. Such addition is noticed to increase the sensitivity and decrease the temperature coefficient of resistance (TCR) of the thin film sensors. Improved sensitivity by 151% and 119% for Macor and Quartz sensors has led to increase in strength of the temperature response of the sensors during dynamic calibration experiments. Though heat flux recovery is seen to have encouraging agreement for all the sensors, sensitivity enhancement is noticed to be more prominent and advantageous for Macor based sensors. Present studies recommend adequately finished substrate for better adhesion. Further, use of MWCNTs is advisable especially for low heat flux measurement and also for Macor substrate since either situation demands the higher sensitivity to increase the output response.

表面传热测量是许多研究问题中的重要方面。在这种情况下，薄膜热通量传感器（TFHFS）因其快速响应和高精度而被广泛考虑用于热通量测量。在本研究中，在制造TFHFS的同时，将多壁碳纳米管（MWCNT）与铂混合。注意到这种添加增加了薄膜传感器的灵敏度并降低了电阻温度系数（TCR）。Macor和Quartz传感器的灵敏度分别提高了151％和119％，从而在动态校准实验过程中提高了传感器温度响应的强度。尽管热通量恢复对于所有传感器都具有令人鼓舞的共识，但对于基于Macor的传感器，灵敏度的提高却更为突出和有利。当前的研究建议适当抛光的底材以获得更好的附着力。此外，特别是对于低热通量测量以及Macor基板，建议使用MWCNT，因为这两种情况都需要更高的灵敏度来增加输出响应。
